"Cherry blossom" - symbol for Japan -

Daigo Cherry Blossoms

Japan extends north and south from Hokkaido to Okinawa. Cherry Blossom Front lands on Okinawa Prefecture in late January, moves northward, and finally reaches Hokkaido in early May. In many parts of Japan, cherry blossoms are at their best from late March to early April.

Cherry trees have a wide distribution in north temperate regions. Flowering cherry trees are widely distributed in Asia, such as China, Korea and Japan, whereas cherry trees bearing edible fruits are widespread in Europe.

Since ancient times in Japan, it has been believed that deities of harvest dwell in the cherry trees and the trees have been considered important. In the eighth century, cherry trees were not so popular as plum trees from the effects of Chinese culture in which plum trees were more valuable than them. After the sending of envoys to Tang China was abolished in 894, the indigenous Japanese culture was developed and cherry trees became the mainstream of flower viewing. It is said that Emperor Saga's cherry blossom viewing party held in 812 is the first viewing event of cherry blossoms on record and later it came to be held as a court function hosted by the successive emperors. In 1598, the Daigo Flower Viewing, the most gorgeous cherry blossom party which became history, was held at Daigo Temple in Kyoto. Hideyoshi Toyotomi, who unified the country as the leader of the territorial lords and the chief adviser to the emperor in the period of Warring States after more than a hundred years of civil disorder, reconstructed the devastated temple, and had 700 of cherry trees brought in to be transplanted. In company with 1,300 guests, including his son, wife and mistresses, he celebrated the beauty of spring through the flower viewing. In the early 18th century, cherry blossom viewing became widespread among town people in Edo, or current Tokyo, by a policy of the eighth Tokugawa Shogun, who had cherry trees planted in Asukayama, Mukojima and other places to make recreational areas for them.

There are ten original cherry species in Japan. Cherry trees mutate and crossbreed easily, so now more than a hundred of varieties grow wild in Japan and more than two hundred of the garden plants have been developed from them. Taiwan cherry trees grow naturally in the area from southern China to Okinawa Prefecture. The typical variety in Okinawa Prefecture has drooping scarlet red flowers and blossoms in January and February. The Yoshino cherry is well known as the most popular cherry blossom in Japan and makes up 80 percent of cherry trees growing in Japan.

The Yoshino with good appearance grows very fast and is easy to grow, but it is said to have a short life span of sixty years if it is not much cared for, compared with Yama-zakura having a life span of hundreds of years. It is supposed to be a crossbreed of Oshima-zakura and Edo Higan-zakura. However, it is incapable of reproducing trees with the same characteristics as the original by crossbreeding because every Yoshino generates from the same genes and it has the property of self-incompatibility, which refers to inability to self-fertilize or fertilize the other plants that are genetically the same to reproduce the same ones. Every Yoshino is a clone from the original. It is reproduced by grafting a scion on a stock or planting a cutting. The first Yoshino tree was sold at Edo Somei Village, a cluster of gardeners, around the middle of the 19th century. Before that, the Yama-zakura, a tall-growing and long-lived species of wild cherry, had been typical of the cherry since long ago. The cherry trees on Mt. Yoshino in Nara Prefecture, one of the most popular cherry blossom viewing spots, are Yama-zakura. The flowers of the Yoshino open before their leaves come out.

The cherry is a shallow-rooted plant, so treading down the earth around the roots causes difficulty in breathing of the roots, and then hinder the growth and causes destructive rot of them. Cherry blossoms must be seen at a distance.

The Japan Weather Association and several private weather information companies announce the forecasts of the opening dates when five or six flowers bloom on the sample Yoshino trees and the peak bloom dates on which more than 80 percent of the blossoms are open in the season. During the season, the places famous for cherry blossom viewing across Japan are alive with people having a picnic under blooming trees and taking pictures of the delicate blossoms.

The biggest cherry tree in Okayama Prefecture would be Daigo Cherry Tree with the height of 18 meters and the branch extension of 20 meters. Judging from a lot of documents, the lone tree is estimated to be 700 years old. On the other hand, the local people believe it to be 1,000 years old. It is standing on a hill in a peaceful countryside in Maniwa City, located in the north of the prefecture. Daigo Cherry Tree was named after Emperor Godaigo, who stopped by the tree when exiled to the Oki Islands in 1,332. Kakuzan Park, or Tsuyama Castle, in downtown Tsuyama is chosen as one of Japan's Top 100 Cherry Blossom Viewing Sites. About 1,000 cherry trees in the castle site come into bloom around the beginning of April. Tsuyama Cherry Blossom Festival is held in and around it from April 1 to April 15 every year.

"First picked tea leaves" - with plenty of flavor -

Tea Picking

Most tea produced in Japan is green tea. Tea leaves are easily oxidized. Freshly-picked tea leaves are heat-treated to inhibit oxidizing fermentation in Japan. Green tea refers to the unfermented one. It is characterized by having the aroma of its fresh leaves and containing sweet and bitter tastes and astringency. Green tea includes a lot of vitamins whereas black tea contains little vitamins. Normal sencha tea, a typical Japanese tea, accounts for two third of the tea produced in Japan. The first picked tea of the year has little astringency and bitterness, and plenty of flavor with the aroma of the fresh leaves. It is harvested from late April to early May. The eighty-eigth day after the first day of spring in the Japanese traditional calendar, May 1 or May 2, has been considered the best time for harvesting tea. Generally, tea leaf plucking machines are used to reap the leaves except high-grade tea and tea in pocket-size tea gardens.

After the opening of Japan to the world in the middle of the 19th century, tea supported the Japanese economy as an important export item to the Western countries, mainly to the USA, along with raw silk. At the market's peak in 1917, about 31,000 tons of tea was exported. However, the increase in export of low-cost tea from India and Ceylon caused the decline in the one from Japan early in the 20th century. With the shift to growth led by domestic demand, tea is deeply rooted in the life of the Japanese.

Hard water with high content of calcium and magnesium is not suitable for green tea because it lightens the taste in response to catechin and caffeine contained in it whereas soft water is suitable.

Catechin as an astringent component leaches out in water at a high temperature of more than 80 degrees Celsius or 176 degrees Fahrenheit. Sencha tea that is made from finely processed burgeons of tea plants grown without blocking out sunlight contains a lot of catechin and less theanine. Theanine as a flavorful component is dissolved in water at a low temperature of more than 50 degrees Celsius or 122 degrees Fahrenheit. It is a major amino acid component which is further contained in earlier picked burgeons, notably first-picked ones. It inhibits excitatory action of caffeine. Gyokuro, a refined green tea made from tea leaves grown shielded from the sunlight before harvested, richly contains theanine as a flavorful component. Konacha tea is the powdery fragments collected in the finishing process of sencha and gyokuro. Basically, sushi restaurants use it.

Matcha tea was brought from Southern Song China about 800 years ago as a medicine by Eisai, a Zen priest born in Okayama. In contrast to Sencha tea, whose drinkable ingredients are extracted in hot water, matcha tea is made by powdering dried tea leaves without kneading. Tea, along with the manners on how to drink it, spread among Zen Buddhist temples and later among the samurai class. The tea style of refined simplicity was established by Juko Murata in the late 15th century and completed by Sen no Rikyu in the late 16th century. The three Senke schools of tea ceremony, Omote-Senke, Ura-Senke and Mushanokoji-Senke, originate from Sen no Rikyu. Omote-Senke and Mushanokoji-Senke schools feature making a thin cover of bubbles on tea in a cup with a bamboo tea whisk, while Ura-Senke school is characterized by producing a generous foam like cappuccino. It is said more than half of tea ceremony students belong to Ura-Senke school now. In 1738, a method of making sencha tea was developed by Soen Nagatani and the reasonably priced tea spread among common people.

Nikkan Bancha tea of Mimasaka City, called Mimasaka Bancha or Sakushu Bancha, is nationally known and it is one of the local specialties of Okayama Prefecture. Unlike sencha tea and other high-grade teas, the tea leaves are picked between the middle of July and the middle of August. In its unique method for production, the tea leaves are dried in the sun, with the tea juice poured over them. Having less bitterness, it is easy to drink for many people without distinction of age, including babies.

"Koi-nobori" - carp-shaped streamers -


May 5 falls on Children's Day, which is a public holiday set aside in Japan to respect children's personalities, celebrate their happiness, and appreciate their mothers. Japan has a custom of celebrating the day with carp-shaped streamers and windsocks called koi-nobori flown outside from April through early May. Koi means carps and nobori refers to streamers. The carp is a fish which can survive not only in clear streams but also in marshes and ponds with very strong vitality. Parents wish their sons to follow the strong vitality. The decreasing number of families with children hoists koi-nobori in their garden because of a drop in detached houses with a large garden and increased collective housing such as apartments. Now, however, a large number of koi-nobori are decorating the landscape of Japan with the aim of regional revitalization and the attraction of tourists. Koi-nobori sets suspended from a ceiling or a decorative base and those for veranda can be easily installed without the need for a wide-open space. Today they penetrate general households.

The origin of koi-nobori is derived from a Chinese legend. It says that there was a waterfall called the Dragon's Gate which was too rapid for most carps to leap over in a stream of the Yellow River and that carps which could climb it would turn into dragons. The carp which had tried to overcome the great difficulty became a symbol of strength and success in life. In the middle of Edo Period (1603-1867) when town people had more economic power, they began to fly streamers representing carps against samurai families that hoisted streamers with their family crest on May 5, one of the five seasonal festivals in the lunar calendar.

Originally, only a black koi-nobori representing the first son was hung to celebrate the growth of the eldest son. The scene was depicted in ukiyo-e paintings such as that depicting a black koi-nobori large enough to cover the full-screen with a view of Suido-bashi Bridge across the Kanda River of Surugadai, a samurai district, in the background by Hiroshige Utagawa. A red carp began to be added after the Meiji Restoration when colorful living carps which were derived from black carps appeared in the market. The black koi-nobori started representing the father, followed by a smaller, red koi-nobori representing his eldest son because patriarchal values in the family became significant. After the Second World War, the red carp came to represent the mother of a family and an additional blue koi-nobori symbolized their child. These days koi-nobori in various colors, including green, orange and gold color, are added to the set in order to represent all the family's children.

A typical koinobori set consists of a pair of arrow-spoked wheels with a ball-shaped spinning vane on the top of a pole, a top tubular streamer in five colors coming from five natural elements and three carp-shaped streamers. It is said that the arrow-spoked wheels with a ball-shaped spinning vane acts as a landmark to refer the gods to the families with a boy or boys. The tubular streamer is believed to protect children from evil.

A local koi-nobori maker in Wake Town, located in eastern Okayama Prefecture, has the largest market share in Japan. Carp streamers, installed by the company, are put on display in the international terminal of Okayama Momotaro Airport during the season. By the way, the entrance of the Prime Minister's official residence is decorated with their koi-noboris. In the Yoshii area of Ibara City, 50 koi-noboris span the Oda River from mid-April to mid-May. Koi-noboris are also flying in the breeze at Enyo-tei House in Okayama Korakuen Garden and Children's Day is celebrated with several activities.

Families with little boys also celebrate Children's Day by displaying Japanese armour, helmets or Warrior dolls called Musha ningyo in the houses.

Children's Day is part of the Golden Week holiday composed of some consecutive holidays, starting with Showa Day on April 29 followed by Constitution Memorial Day on May 3, Greenery Day on May 4 and Children's Day, with well placed weekends.

"Hay fever" - popular allergy in Japan -

Cedar Pollen

It is said that one out of four people in Japan is suffering from pollen allergies. According to a 2019 survey of Weathernews, more than half of the population of Japan except Hokkaido and Okinawa Prefectures, where there are few cedar trees known as Sugi in Japanese and cypress trees known as Hinoki, have pollinosis.

It is inferred that 70% of hay fever is caused by cedar pollen scattering between February and April. Japanese cedar trees, the Cryptomeria japonica, were planted for wooden building materials and flood control after World War Two. The trees grow exceedingly rapidly and are straight and tall. Peak pollen collection from mountains occurs in cedar trees of 30 years or older. The hay fever was first reported in 1964 and the number of people suffering from it increased drastically in the 1970s when 30 years had passed since numerous Sugis were planted.

After the season of cedar pollen, that of cypress pollen comes in March and the peak continues for some two months. In the Kansai region, artificial forests of cypress trees have a total area as large as that of cedar trees. But counts of airborne cypress pollen are generally much less than counts of cedar pollen because many of the trees in the area are still very young.

Anti-hay fever masks reduce exposure to airborne pollen by 60 percent to 80 percent. So many hay fever sufferers wear masks in spring. Cedar trees producing a large amount of pollen are cut down and varieties developed to produce much less pollen have been planted in order to reduce the damage of pollinosis attributable to the pollen.

"Hydrangea" - flower native to Japan -

The hydrangea

The hydrangea is the sign of the rainy season in Japan. It starts to bloom in late May and is best viewed in late June in the central region of Japan including Tokyo and Okayama Prefecture. The flower color ranges between red and blue through purple. The soil chemistry is a main factor that determines the bloom color. Japan is made up of volcanic islands. The Japanese archipelago is covered with volcanic ash, weakly acidic soil. Acidic soil usually produces a bloom color closer to blue. A kind of anthocyan dye contained in hydrangeas responds to the aluminum ions dissolved in the acidic soil and absorbed through the roots. It results in bluing of the petals. In Europe, the flowers thrive in dry alkaline soil having a low solubility of aluminum ions. It turns them pink or red.

The name hydrangea comes from the Greek "hydor," referring to water, and "angeion" meaning vessel, derived from the shape of its capsular fruit. The plant needs plenty of water to make up for moisture loss due to evaporation from stomas of leaves. The part generally called flower is not a flower, but a calyx, or an ornamental flower to attract insects. The petaloid part is sepals, and the flower is a tiny part with five petals in the center.

Garden hydrangeas originate from lacecap hydrangeas which grow wild by the Pacific coast south of Kanto region in Japan. In 1789, an English botanist donated hydrangeas growing wild in the east of the Yangtze River in China to the Royal Botanic Gardens. They were originally brought from Japan to China and went wild there. Hydrangeas brought from Japan by plant hunters gained popularity in Europe. In the early 20th century, improvement was made repeatedly in European countries such as France, the Netherlands, Belgium and Germany. And then improved mophead hydrangeas with ball-shaped clusters of decorative flowers were re-imported to Japan.

For a long time, the hydrangea had not been popular among the Japanese due to its negative images, such as volatility and infidelity. However, there are a lot of hydrangeas in gardens of temples located in areas where plagues spread in the past. Many died from sudden temperature changes in the rainy season until modern breakthroughs in medical technologies. The hydrangeas, which bloom in the rainy season, were offered to dead persons at the temples. After the Second World War, they started to be used as valuable tourist attractions. Many temples began to plant mophead hydrangeas, varieties from Europe, in their gardens.

In Okayama Prefecture, Daishoji Temple in Mimasaka City, Chohoji Temple in Tsuyama City and Ohtakisan Seihoin Temple in Bizen City are also called Hydrangea Temple and a lot of tourists invade the temples during the blossom season.

"Wagasa" - Japanese-type umbrellas -


The rainy season in Japan sets in around the middle of June, lasting more than one month. Umbrellas are indispensable when we go out this season. Traditional Japanese umbrellas called wagasa are made with bamboo-strip ribs covered with washi paper waterproofed with plant oil. There are four main types of wagasa: bangasa, janomegasa, wahigasa and maigasa.

Bangasa is simple and sturdy. By contrast, janomegasa with snake-eye pattern of concentric circles on paper features its fashionable and cool design as well as its slender shape. The pattern resembles the eye of a snake that is considered to be a messenger of a deity, and the eye is believed to have the effect of charming against evil spirits. Its basic color such as red or dark blue contrasts with the white doughnut-shaped pattern. The relatively lightweight umbrella is generally used for women. It is also one of the typical props of Kabuki, a traditional Japanese performance art. Wahigasa is a Japanese-type parasol. High-priced maigasa is made of silk and has beautiful transparency which makes performers look glamorous. It is used mainly for Japanese traditional dance performance and Kabuki. The design is simple enough not to obstruct the pattern of the kimino which a performer is wearing. Wahigasa and maigasa are made without coating the surface with oil. They play an important role to serve as a foil to a bride in a Japanese-style wedding party.

Wagasa originates from a canopy used for sunshade or charm for Chinese nobilities. At first, it spread as an installed canopy or a larger parasol held over the head of a court noble by a servant in Japan. It began to be used from the medieval period as waterproof and openable rain gear in an unassisted state. Meanwhile, the common people used a sedge hat and a straw rain cape as rain gear. Around the beginning of the 19th century, wagasa was favored by the general masses as well.

Peter F. Drucker, known as the Father of Modern Management, mentioned in one of his books that the concept of marketing was started by the Mitsui family, the founder of the Mitsui Group, who began to run a dry-goods store in Edo, current Tokyo, more than 300 years ago. In the time when it was common for merchants to sell goods on credit, they started business for cash to minimize a bad debt loss and mark down goods, adopting a fixed price policy. One of their epoch-making strategies for promotion is that they lent their wagasas printed with a number and the store's name written with large-sized characters to customers and passersby when raining. The streets were filled with the wagasas with the store's name on. Bangasa literally means a numbered umbrella. For this reason, the umbrellas came to be called bangasa. Thus the store's name spread throughout the town.

Kabuki triggered a janomegasa boom among the town people in Edo. In a kabuki play called Sukeroku: Flower of Edo, the audience was attracted by a cool-looking hero who appeared with a janomegasa in his hand on the stage.

After folded into a compact shape, a wagasa is kept close and folded if you hold the top, not the handle. It stands with the handle touching the ground when put in a stand. In addition, it prevents rainwater from entering the inside of a wagasa, the unoiled part. A longer drying time is necessary in drying it.

Japanese-style umbrellas are much less popular than western-style umbrellas now. They are used mainly as interior decoration like lamp shades. At some events, including tea ceremonies and festivals, they play a role to add more opulence to them.

Some shops such as kimono shops and umbrella shops rent wagasas as well as sell them. The Japanese Weather Association has lent out to visitors from other countries as part of the Heatstroke Zero Project in summer at several gardens in cooperation with Tokyo Metropolitan Park Association since the summer of 2016. Wagasa Denho Kan, or Folklore Umbrella Museum, located in Yonago City of Tottori Prefecture on the northeast of Okayama Prefecture, provides an observation tour of the manufacturing processes of wagasas. The base for making wagasas, located in Yodoe, offers a workshop where applicants with reservation can experience affixing paper over a frame of bamboo-strip ribs.

Wagasa lovers can enjoy themselves in Okayama Prefecture. Some events held in the prefecture features a wagasa exhibit. Among them are "Kurashiki Spring Light Festival" in Kurashiki Bikan Historical Quarter, and "Special Late-Night Garden" at Okayama Korakuen Garden.

"Yukata" - casual summer kimono -

Girls in yukata

In summer Japanese people enjoy summer dance festivals and fireworks festivals. Many families, couples and friends in yukatas add to the festive mood. Yukata is one of the seasonal charms of summer.

Yukata is an abbreviation of "yukatabira", which means an unlined kimono that was made from hemp and worn during taking a steam bath in the Heian period before the first samurai government was born. The nobles wore it to protect their skin from hot water vapor, get rid of sweat and hide his or her naked body. In the middle of the 19th century, yukatas made of cotton were widely worn by common people as garments worn after bathing. In the late 19th century, they obtained popularity as informal summer clothes because they were cool and comfortable.

Typical traditional female yukata has indigo blue design on white ground or its reverse. People used to wear a white yukata on which the pattern was dyed in indigo blue in the daytime and indigo blue one with white patterns in the evening because the ground color of white looks cool in the hot and humid daytime in summer and the indigo blue dye has an effect of keeping insects off in the evening when they are activated. Now, yukatas in pastels and bright colors are in fashion, especially among young women.

Black and dark blue yukatas without patterns or with simple patterns such as thin striped patterns and splashed patterns are popular among men.

Yukata is suitable for being used in the hot and humid summer of Japan. It is made of breathable fabrics such as mesh cloth. There are several yukata rental shops around Kurashiki Bikan Historical Quarter. Some tourists rent a yukata to walk about the historical townscape, wearing it.

"Cool touch fabric products" - fabrics that keep you cool in the heat -

Cool Touch Fabric Products

A wide variety of cool touch fabric products go on the Japanese market in summer. Cool touch textiles are cool to the touch. The fabric materials are used for bedding which includes pillows and bed pads, clothes such as underwear and pants, and small articles like towels and socks. These products are getting more and more popular among Japanese people year after year.

Why do cool touch fabrics create a cooling touch? They help lower skin temperature by heat conductance. Heat flows from higher temperature to lower temperature. Accordingly, heat is transferred from skin to textiles. Textiles with fabric contact coldness are characterized by being higher in thermal conductivity and thermal diffusivity, having structure that can contain more quantity of water which is twenty times higher in thermal conductivity than air, and being slightly hard to the touch. Polyethylene has a higher contact cold sense value than other textile fibers, whereas it has low water and moisture absorption properties. On the other hand, linen, rayon, ramie and cupra are high in both of them.

Japanese traditional clothes for summer season, yukatas, make use of high technology in recent years. Cool touch fabric yukatas keep us cool in the heat.

"Peach" - specialty food of Okayama Prefecture


Peaches were brought to Japan from China in the Yayoi Period when an agrarian society based on food production by rice-paddy cultivation had been established in Japan. Many stone seeds of peaches were found from remains in the period. Peaches had been considered to expel evil spirits and bring longevity. They were much smaller and less juicy than the present ones. The varieties which are widely distributed to Japan today were developed based on varieties from China and Europe about 150 years ago. More than 30 varieties have been developed since then.

With sunny climate and few rainy days, Hakuto, or White Peach, which is a specialty food of Okayama Prefecture, was discovered accidentally in 1899. The fruit with translucent white rind and flesh melts in the mouth. Shimizu Hakuto, a variety of Hakuto, is said to be the best of all the varieties, called "Queen of Peach". Peaches of Okayama Prefecture are grown with protective bags around the fruits after becoming the same size as ping pong balls. The bags protect them from rain, wind and garden pests. And then, they eventually become the same size as softballs and are harvested. Yellow peaches popular in Western countries are produced mainly for processing use in Japan.

The outside of the peach around a stem remains green when unripe. Peaches which have symmetric shapes taste great. The very best season for eating peaches is from mid-July to August.

Cooling peaches in a refrigerator for a couple hours before eating is a key to deliciously eat them. Keeping them in a fridge for a long time spoils the flavor and the sweetness. Therefore, it is important to store them at a normal temperature unless you eat soon.

Okayama Prefecture is the largest producer of white peach varieties whereas it is the sixth largest of all the peaches in Japan. Processed food of peaches is welcomed by tourists as souvenirs. Many kinds of peach products such as steamed peach-jam bun, peach vinegar, peach sake are sold at main stations and famous tourist spots.

Some tourist farms offer experiences of harvesting the high-quality peaches with your own hands and tasting them on the spot.

"Amazake" - nourishing drink called "drinkable IV drip" -


"Malted rice amazake" is a traditional sweet beverage made from fermented rice. It is made by keeping steamed rice, rice malt and water at a temperature of 55 to 60 degrees C. The milky drink is called a drinkable IV drip because it is high in glucose, amino acids, vitamin B complex, and minerals. The other kind of amazake, which is made from sake lees and sugar, contains alcohol content of less than one percent with higher calories than malted rice one. This amazake is not referred to as a drinkable IV drip because it contains far less glucose compared with the other, but it is rich in resistantprotein which lowers bad cholesterol and raises good cholesterol, and s-adenosylmethionine which has inhibitory effects on liver function failure, depression and arthritis. The mixture of it and refined water can be used as a face pack.

Amazake was drunk cold on a hot summer's day during the Edo period. More people died in summer because summer heat deprived them of their physical strength in no time. People drank nourishing amazake to preserve their strength. Today, amazake is enjoyed as a warm beverage during winter. However, amazake is regarded as a drink in hot weather again these days. Amazake has been used as a summer season word in haiku, Japanese seventeen-syllable poem.

Malted rice amazake can be eaten by spreading on bread as well. It can be substituted for sugar in cooking. Amazake which is a fermented food goes well with yogurt and cream cheese.

Many amazake products are made by soy source companies, miso companies and sake breweries. Marumi Koji Honten located near Minagi Station on JR Hakubi Line produces malted rice amazake made from natural farming rice without any use of pesticides, chemical fertilizers and organic fertilizers. It is a miso company which won the Minister of Health, Labour and Welfare Award given to excellent workplaces, organizations and persons for their contributions to the fields of health and safety in 2016.

"Haunted House" - Why are haunted houses so popular in summer? -

Haunted House

Many people in Japan flock to haunted houses in summer. They participate in the event with a storyline and a mission as one of the characters. For example, at one haunted house, a doll which looked like a baby was handed at the entrance and participants had to deliver the baby to the mother waiting at the exit while guarding it from demons lurking in darkness. Stories stimulate their imagination.

Why are haunted houses so popular in summer? Summer is the season when Japanese people welcome the souls of the dead since long ago. It was said that ghosts that held a grudge also came back to the world of the living. In the Edo Period, a lot of plays to repose the departed souls were staged at kabuki theaters in summer. During the season, top grade actors took a vacation and young actors appeared on the stage instead of the popular actors. They played novel programs for attracting audiences. When people feel fear, noradrenalin raises body temperature to prepare for any distress. However, that makes the body feel cold because the temperature on the surface of their skin does not rise yet. In other words, blood runs to major organs like the heart and major muscles such as limb ones when people get scared. That worsens the flows of the blood to the tips of the arms and legs, and the surface of their skin. As a result, they feel chilly. In the Edo Period, it was common for town people to go to a kabuki theater in order to enjoy the cool in summer.

The history of haunted houses in Japan can go back to 1830, when the nation was unsettled owing to frequent famines, natural disasters, and other calamities. It is said that it originated with a hut which a doctor built in his private garden in a suburb of the city of Edo. However, it was demolished at the behest of the local governor three months later. In 1839, a temple in Edo put on various shows in the precincts. One of them is the model of today's haunted houses. A boom of haunted houses started in the 1910s. Haunted house exhibitions and temporary haunted attractions at shrines and temples entertained many people by stimulating the five senses through light, sound, odor and other factors. After World War II, a lot of department stores and amusement parks began to operate horror-themed events.

A typical traditional Japanese ghost has no legs and feet, wearing a plain white kimono with dishevelled hair. In most cases, a female ghost is the main character in a ghost story. A woman treated cruelly by a man becomes a vengeful spirit and curses him. She often appears near water such as a stream, mostly under a willow tree, and a well.

These days in Japan, most haunted house attractions are created by haunted house producers. Hirofumi Gomi, the leading producer, devised a new type of haunted house attractions having a story line and a mission more than a quarter of a century ago. A variety of haunted attractions, including haunted trains and buses, can be enjoyed as well.

Statics show annual per capita consumption of tomatoes in Japan is only nine kilograms whereas the global average is 20 kilograms. The main reason would be that cooked, concentrated tomatoes that occupy a large share of consumption rates in other countries are not so popular as much as fresh tomatoes among Japanese people. The Japanese prefer eating raw tomatoes, usually used in salads, to cooked ones, while people around the world generally eat the vegetable by heating. But red tomatoes are being recognized for their rich lycopene in Japan.

Tomatoes are roughly categorized into two types, depending on the color of their skin in Japan: red and pale pink. Red tomates characterized by its relatively strong acid taste and rich flavor, thick, yellow skin are often cooked in a sauce or a soup. Pale pink tomatoes featured by its sweet taste, light flavor, thin, transparent skin, and soft flesh are mainly eaten fresh as salads and garnishes.

The tomato was originally introduced to Japan in the middle of the 17th century. It was used for ornamental purposes at the time. Red tomatoes were brought again from the United States as food in the second half of the 19th century. But the tomato was not so popular because the vegetable with an unfamiliar smell and color were kept at a distance by Japanese people. After the Second World War, it became popular by the introduction of pink tomatoes, along with the trend of westernization of the foods.

The most popular variety of tomatoes in Japan is Momotaro. The pink tomato started being developed by Takii Seed, a Japanese nursery company, in the late 1960s. At that time, pink tomatoes were picked green because ripe tomatoes bruised easily in transit and at stores. Red tomatoes are harder to damage than pink tomatoes. But Japanese people had a storng image that they were used for processing. To clear this problem, Takii undertook a project to develop a variety of hard pink tomatoes. After trial and error, the invention was achieved in 1983 and then the product was put on the market in 1985. Now 31 varieties of Momotaro have been developed as a result of a series of breeding works and 22 varieties are sold throughout the nation.

It is said that the best season for tomatoes is summer. But summer in Japan is so hot and humid that it is hard to harvest tomatoes that have good taste. The real best seasons to eat them are the period between spring and early summer, and autumn.

Okayama Prefecture is suitable for producing tomatoes because the prefecture has little rain and the vegetable does not like rain. Tomatoes in Okayama Prefecture are grown mainly on highlands located in the north of the prefecture. "Ripe Tomato Jelly", a skinned ripe tomato in jelly, is very popular as a specialty product of Okayama.

"Grape" - Okayama is a large producer of premium grapes. -


Okayama Prefecture characterized by little precipitation and a mild climate is famous as a large producer of premium grapes such as the Muscat Of Alexandria with rich aroma and flavor, the Pione with deep flavor and large and juicy pulp, and the Shine Muscat with high sugar contents and juicy pulp in Japan. According to the National Federation of Agricultural Cooperative Associations Okayama Office, the production amount of the Muscat Of Alexandria accounts for 95 percent of the nation's total amount. It originated from the glasshouse grapes that two horticulturists succeeded in growing 130 years ago. Since that time, grapes have been made by using greenhouses to control humidity and temperature and to avoid raindrops. The Pione was developed in Izu City, Shizuoka Prefecture, 60 years ago. Grape farmers of Okayama began to work on it 50 years ago. Today, Okayama makes up 40 percent of the production and it is the highest in the nation. The Shine Muscat is a new variety developed by the National Agriculture and Food Research Organization and registered in 2006.

According to OKAYAMA FRUITS Information Site, a unique feature of the grapes produced in Okayama is that they are commonly oval-shaped like rugby balls while others are formed into the shape of an inverted triangle. The cultivation techniques of grapes for eating raw remains at the world-class level. They are widely sold in stores from August to October.

"Red rice harvest" - red carpet of ancient rice -

Red rice paddies

Red rice, a variety of ancient rice, is native to Southeast Asia. Japonica-type red rice was brought to Japan before brown rice 3,000 years ago and cultivated all over the country in the seventh and eighth centuries. The seed coats and the pericarps of the unpolished rice contain red pigments, kinds of polyphenol such as catechin and tannin. Today, it draws attention as a health food because it contains more protein, vitamins and minerals, compared with brown rice.

It was believed that red color had power to remove wickedness in ancient times. Shinto rituals such as the Red Rice Planting Festival have passed down up to now in three regions, Tanegashima Island of Kagoshima Prefecture, Tsushima Island of Nagasaki Prefecture and Soja City of Okayama Prefecture. In Soja City, red rice is cultivated to make an offering to the deities in the rice paddies specializing in the red rice used for religious services of two divided shrines and rice paddies of followers on duty, located in Shimpon district, and then it is offered at the beginning of the year and a ritual held in the eleventh month of the lunar calendar.

Indica-type red rice was brought to Japan from China in the 14th and 15th centuries and widely cultivated in the area except northern Japan. It is highly resistant to bad environments, plant disease and insect pests, and grows faster.

Most of red rice disappeared from Japan in the late 19th century. However, Japonica-type red rice started to attract attention as a health food and a resource for tourism in recent years. It is preferable to cook by adding 15 percent of red rice into white rice. There are red rice paddies located across Bitchu Kokubunji Temple in Soja City. Red Rice Festa, a live concert by J-pop singers with the red rice paddies in the background, is held at the temple in the middle of September.

"University festival" - a big part of Japanese university life -

Culture Festival

University festivals are a big part of Japanese university life, organised and run by executive committees of students. Universities give advice to them through the student support office and festival-related staff. Many of them are annually held in autumn while some are conducted in spring. Not only students but also local residents are looking forward to the festivals. A large variety of food booths running by students offer culturally-based foods. Basically, members of student seminars and extracurricular activity groups arrange concerts, exhibitions and other events to present their research and activities. A considerable number of universities provide walking campus tours and trial lectures for prospective students during the festivals. At some large university festivals, performances by famous singers, comedians, or other celebrities, and beauty contests spice up them, each with the total number of visitors ranging from 100,000 to 200,000.

The origin of the festivals dates back to the year 1900, when Tokyo University of Foreign Studies started to give presentations, such as readings and speeches in foreign languages, in front of over 1,000 people. The current form of the festivals was created after the establishment of the present national university system in 1949.

There are some unique university festivals, especially in Tokyo. Aoyama Gakuin University in Shibuya plans and executes an annual high quality fashion show at a chapel and its students model dresses. "Harvest Festival" held at Tokyo Agriculture University features distribution and sales of vegetables grown by students and sales of local food and international food at refreshment stalls.

Seasonal Words, "Matsutake mushroom"

Matsutake mushrooms

There is a well-known saying in Japan that matsutake mushrooms have the best aroma and shimeji mushrooms have the best taste. The unique and a bit strong flavor of matsutake mushrooms has been preferred by Japanese people for over 1,000 years. The fall delicacy is regarded as an exclusive product like a truffle now. But, up to the mid-20th century, the brown mushrooms were very available for ordinary people while shiitakes were rare and expensive. The forest product is mainly eaten grilled, mixed into rice, boiled or steam-boiled in an earthenware teapot to enjoy the flavor in Japan. It is important to have a matsutake whose cap is not yet completely open, otherwise the aroma has faded away.

Matsutake mushrooms grow on roots of more than 20-year-old Japanese red pine trees, which live in nutritionally poor and dry soil. Domestic production of matsutake in Japan has been sharply reduced to around 100 tons due to massive deforestation of the trees for wooden pulp after the Second World War, devastation of the forests that spark production of soil rich in nutrients, pine wilt disease, after reaching a peak of 12,000 tons in 1941. It is also said that effects of global warming has exacerbated a shorp drop in yield for the autumn appetite. Today 95 percent of matsutake in the Japanese market comes from overseas countries. The largest supplier is China, followed by Turkey, the U.S. and Canada.

The International Union for the Conservation of Nature and Natural Resources (IUCN) announced on July 9, 2020 that matsutake was designated as an endangered species. It was categorized as “vulnerable,” the third, classified as critical the same as bluefin tuna in the Pacific Ocean. But, no restriction regarding the international trade in the species has been imposed. Matsutake has difficulty in carrying out artificial culture. Various research institutes, including Kindai University, are tackling to force matsutake. However, the techniques have not been established yet.

Okayama Prefecture ranks third in the nation in the annual yield for matsutake, after Iwate and Nagano prefectures. The mushrooms are harvested in October in the prefecture. They are at their peak from mid-October to late October. This year, a good harvest throughout Japan is bringing down the price of matsutake.

"Sake brewing" - featured by multiple parallel fermentation -

Steaming of Japanese Sake Rice

Japanese sake is mainly made from polished rice, water and rice malt. Rice is harvested between September and October. The rice grain for sake brewing is bigger and softer than that for cooking. Sake brewing is carried out from October to March, especially from December to February during the cold season, except the major sake manufacturers which have automatic temperature control devices. Sake brewing starts after harvest. The season is the best time to facilitate temperature control in vats in fermentation and to prevent unnecessary bacteria from developing in them.

Rice is milled to remove the outer portion of the grain which contains protein and oil, a cause of unfavorable taste of sake. Super high-quality sake with fruity aroma is brewed from rice grain polished to 50 percent weight or less. After the rice is steamed, Aspergillus oryzae is inoculated into the steamed rice for producing rice malt. Then, yeast mash, which mass-produces yeast, is made from the steamed rice, the rice malt, water, and sake yeast. The rice malt helps starch in the yeast mash and unrefined sake change into glucose. Sake brewing is characterized by a complex fermentation and saccharification process occurring in a vat in parallel, called multiple parallel fermentation. The raw unrefined sake is pressed to separate the sake from the lees. Lastly, it is pasteurized twice, or once, except the liquid which becomes raw sake called namazake.

Hiyaoroshi is seasonal and limited edition sake available in autumn. It is fresher than normal sake because it is heated only once, in spring, during the brewing process. Shiboritate is winter sake. It is fresh sake made from rice harvested in the year, without the final heating process.

With more than 150 years of history, “Omachi”, which have been developed and produced at Omachi located in Okayama City, is well known as the oldest sake rice. It is difficult to grow because it has little resistance to lodging and disease. Having faced the threat of extinction, the amount of production is gradually increasing through the effort of sake makers of Okayama Prefecture and for responding to the demand as a material of sakes with specific class names around the nation in recent years. Its enthusiastic fans are called “Omachist”. They join various sake events held all over the nation, notably the Omachi Summit in Tokyo.

Some breweries offer tours of the sake brewery to visitors with a reservation.

"Yuzu" - citrus fruit deeply rooted in Japanese culture -

Yuzu & Yuzu Products

Yuzu is a yellow-golden colored citrus fruit. It is tarter and more acidic than other citrus fruits and rarely eaten as fresh fruit. The peel with a rough, and uneven surface is highly fragrant and mainly used as flavoring for cooking and making sweets. The flesh tastes like a cross between grapefruit, lemon and lime with a little bit of bitter taste.

Yuzu ripens from November through January. Most areas that produce yuzu are situated in well-drained mountainous regions slightly inland than the temperate coastal regions because the temperature difference between day and night is large enough to put the scent of the citrus in the areas. The fruit is mainly cultivated in Shikoku Island. Kochi Prefecture, located to the south of Okayama Prefecture, accounts for over 50 percent of the production. In Okayama Prefecture, Kumenan Town, located northeast of Okayama City, produces the most yuzu now.

Yuzu has been widely used as an ingredient for Japanese confectionery. Yubeshi is one of the popular yuzu sweets. There are many kinds of yubeshi over the country, including yubeshi without yuzu. A long time ago, it was a portable ration during wartime or for a trip. Maru-yubeshi, or round yubeshi, is a luxurious cake often served at a tea ceremony. It is made from yuzu, powdered glutinous rice, miso, walnuts and other ingredients, varying among every region and producer. After the mixture of all the ingredients stuffed into a yuzu cup and then steamed, it is dried by hanging it on a string outside for weeks or months. A local brand of yubeshi called Bitchu-yubeshi is made in Takahashi City and Yakage Town of Okayama Prefecture. These areas have been known as yuzu production areas. Sheet-like yubeshi of Takahashi City is made by boiling down the mixture of ground yuzu peel, steamed glutinous rice flour, and malt syrup, letting it dry, and being coated with sugar or glutinous rice flour. The production was promoted to support the finance of the Bitchu Matsuyama Domain in the 19th century and then achieved significant results in financial reconstruction through sales of yubeshi as well as other local products in Edo, current Tokyo, and Osaka. The other, called bo-yubeshi, is made by steaming the mixture of powdered glutinous rice, miso, and minced yuzu and being packed in a bamboo-sheath.

Yuzu kosho is a popular Japanese condiment that is made by mixing yuzu and chili paste with salt. There are two kinds of yuzu kosho, green one and red one. The former is made from young green yuzu and green chilies, and the latter is made from ripe yellow yuzu and red chilies. Additive-free red yuzu kosho named Beni-Daruma, which won the Jury's Special Award at Seasoning Championship 2017 hosted by the Japan Vegetable Sommelier Association, is a specialty of the Fukiya area of Takahashi City. Yuzu kosho goes well with various dishes. Among them are buckwheat noodles, grilled chicken and sashimi.

In Japan, there is a legend that taking yuzu-bath on the winter solstice around December 22 prevents catching cold all year round. It is said a public bath originated when they soaked some yuzus in the bath water to attract new users in the Edo Period. The peel is rich in an essential oil component called limonene that helps improve blood circulation through the whole body and affords beautiful skin. The flavor enhances relaxing effects.

Yuzu is deeply rooted in Japanese culture. Food and beverages with the elegant and rich flavor have attracted a number of Japanese people. It has been indispensable for Japanese cuisine. The fragrance component is used in various aromatizing products such as bathing agents and aroma oil. The citrus fruit can last over three months by being put into a plastic bag, hermetically sealed, and then stored at a temperature between 0 degrees Celsius and 2 degrees Celsius.

"Kotatsu" - Japanese heating device -


In winter, kotatsu, a table with a built-in heater to keep our legs and feet warm, had been at the center of the Japanese family before air conditioners became major heating apparatus. The scene of family members getting together around a kotatsu and eating mandarin oranges on the table was a typical image of a family happily spending time together during the winter.

There are devices similar to kotatsu in the world: Spanish brasero , Iranian korsi, and Afghan sandali.

Kotatsu originated from a combination of "irori", a Japanese fireplace that is set in the middle of a room, and a short-legged square-frame covered by clothes, later by a heavy blanket or a thick quilt, dating back to the 14th century. The fire was damped down by covering it with ashes. People kept themselves warm with their legs on the frame. It was especially favored by people living in urban areas abundant in fuels. Later, irori was placed below the floor surface, and it made it easier for users to sit on the floor. Portable kotatsu, a combination of "hibachi", a Japanese brazier, and a long-legged square-frame, replaced the old type kotatsu in the 17th century when tatami mats became popular.

Sunken kotatsu became popular among general people in the early 20th century. Bernard Leach, who is known as a prominent British studio potter, had great interest in Japanese culture, including kotatsu. But he had difficulty moving his legs underneath kotatsu. Sunken kotatsu for housing was first built in his residence. Naoya Shiga, a Japanese novelist called "the god of novels", largely contributed to the spread of it to the public. He gave it a rave in his essay.

The primitive form of the kotatsu that we currently use traces back to the electric kotatsu which Toshiba Corp. launched in the 1950's. Nichrome wire was used in the device heater fixed on the lower face of the top. The product sold explosively. That made the appliance penetrate common households. The spread of it reduced the risk of fires and accidental carbon monoxide poisoning significantly.

As mentioned earlier, kotatsu has lost its popularity since air conditioners became much more popular. Moreover, the number of tatami-mat rooms in which kotatsu is generally used in Japan has decreased sharply. However, it is gradually recovering in popularity in recent years. There is a strong demand for the products for individual use among elderly adults and young people who live alone. Higher-legged kotatsu matching chairs was developed and is spreading through the market.

Kotatsu boat service and kotatsu train service running through an epic scenery offer passengers special experience in Japan. They are vehicles equipped with the comfort of kotatsu heaters. Mogami River Boat Ride running through Yamagata Prefecture is one of well-known cruises with kotatsu. Kotatsu Train on Sanriku Railway Company's Kita Riasu Line, running along the Pacific coast of Iwate Prefecture, is one of the winter attractions in the northern region.

There are some events that use kotatsu in Okayama Prefecture: the Christmas Tree Lighting Ceremony at Kibi International University and a live concert in Soja City Hall's parking lot.

"Oden" - Japanese typical comfort food in winter -


Oden is a typical comfort food in winter for the Japanese. In cold weather, the Japanese hotchpotch is often served on the table for dinner. Oden has been the most popular pot cooking in Japan for a long time. Kibun, a company which mainly makes and sells fishery paste products for oden, reported in their survey that oden had ranked first in all hot pot dishes for 20 years from 2000 to 2019.

Among various theories on the origin, the most widely accepted is that the predecessor of oden is dengaku, a small rectangular tofu skewered, pasted with miso sauce and grilled. There are records about the dish around the 14th century. The skewer resembles dengaku dancers having white hakama trousers and a tall clog like a short stilt on. Its name originated from the performers dancing during rice-planting. Later on, dengaku came to be called oden consisting of "o," a prefix used in the language of court ladies during former times, and "den," an abbreviation of dengaku. In the Edo Period, boiled tofu with miso sauce was also called oden. While various food shops such as udon noodle, eel, and dumpling shops appeared across Edo, current Tokyo, at that time, not only tofu but also eggplants, taro plants, konjak and fish began to be used as ingredients. With the population of single men from outside Edo growing, food stands spread all over the town and became popular. Peddlers also sold oden carried on a pole. Common people enjoyed eating the fast food at a reasonable price. Oden hotchpotch became popular in the late 19th century when soy sauce began to be commonly used. Once having died out in Tokyo, it revived after the Great Kanto Earthquake in 1923. That made with Japanese radish, boiled eggs and fishery paste products, the current style of oden, appeared after the earthquake.

In Osaka, konjak, instead of tofu, was skewered. The stewed dish spread to Osaka and Kyoto around the 1910s. It was called Kanto-daki and improvement was made several times. The improved hotchpotch was offered by cooks from the Kansai region, including Osaka and Kyoto, at the evacuation shelters after the Great Kanto Earthquake.

The hotchpotch was sold at food stands, oden shops and mom-and-pop candy stores from the mid-1920s to the mid-1950s. Later on, powder of oden soup stock capable of easily and simply being cooked became available on the market. As a result, the pot dish came to be typically home-style cooking. A variety of different styles of the hotchpotch have been developed during the last few decades. It varies from high class cuisine all arranged attractively at oden restaurants to that as a fast food simmered in electrothermal oden pots at convenience stores. Around 2005, a boom in cold food, such as cold curry, started and the cold oden boom was created.

Tamashima, a port town located in Kurashiki City, has abounded in marine products for a long time. Since the Meiji Period ( 1868 - 1912 ), plenty of fish landed at Tamashima Port have been processed into pasty marine products mainly in southern Tamashima. After World War Ⅱ, the increase of the production of the pasty products as a primary source of protein contributed to the relief of sufferers from food insecurity. In Northern Tamashima, the production of Japanese radishes was prosperous. There were a lot of factories to produce soy sauce, miso, and sake used as seasoning for oden in Tamashima region. Many poultry farms were in business in the area. These are why Tamashima Oden was created there. Tamashima area has promoted the oden since 2008. The dish features the fishery paste product containing plenty of chicken eggs, called Kasutera.

"Marathon" - one of popular sports in Japan -


The first Japanese Olympic athlete is a marathon runner, named Shiso Kanakuri, who participated in the fifth International Olympic Games held in Stockholm, Sweden in 1912. He could not finish the race due to sunstroke, but reached the finish line at a ceremony in commemoration of the 55th anniversary of the Stockholm Games in 1967.

In the Tokyo Olympic Games in 1964, a Japanese runner got the bronze medal. Another athlete received the silver medal in the next Olympic Games. After those, many Japanese runners began to play an active part in the marathon world. Women's marathon runners boosted their presence in the 1990s and the 2000s. In the 2000 Sydney Olympic Games, Naoko Takahashi won Japan's first ever track gold medal. Mizuki Noguchi got a gold medal in the Athens Olympic Games in 2004. Japanese marathon runners were supported by frontier research. However, the athletes have been engaged in a fierce struggle since the late 2000s by the emergence of marathon powerhouses such as Ethiopia and Kenya. High-speed races in recent years are attributed to those Afriacan runners.

The first Tokyo Marathon in 2007 triggered the nationwide citizen's marathon boom in Japan. Now more than 1,500 races per year are held in the country. There are applications exceeding the capacities at most of them. On the back of marathon booms in China and Taiwan, many runners from overseas countries joined the marathon events. Research says the number of runners and joggers habitually running more than once a week reaches over 5 million people in Japan.

In Okayama Prefecture, Okayama Marathon, which started in 2015, takes place at Okayama City in November. The course starts from the front of the Okayama Prefectural Multipurpose Grounds near Okayama Station, certified by the Japan Association of Athletics Federations. It also has a 4.5 km fun run course. Soja Kibiji Marathon and Tsuyama Kamogo Full Marathon have a few decades of history.

An Okayama-based long-established department store, Tenmaya, established a women's track-and-field club in 1992, when a women's marathon runner from Okayama Prefecture, Yuko Arimori, won the silver medal in the Sydney Olympics. The team has produced many Olympic athletes, including Honami Maeda chosen as one of the marathon runners who represent Japan at the Tokyo Olympics.
