ASIAGAP is a GAP certification program approved by the Global Food Safety Initiative (GFSI).
ASIAGAP includes elements of food safety, environmental protection, occupational safety, human rights, welfare and farm operations as JGAP does.
Because the standards are to be created in line with GFSI Benchmarking Requirements, the food safety element includes an approach based on HACCP, food defense, and the prevention of food fraud.

Izumo Kocha

Izumo, the City of Matchmaking and Mythology

Izumo is a city located in the middle east of Shimane Prefecture. It is known throughout Japan as a “mythical country” and is blessed with a rich history and cultural heritage, including Izumo Taisha Shrine, which has the benefits of matchmaking.
Shimane has the characteristic that there are many cloudy days and has been selected as the No.1 Bihada (beautiful skin) prefecture several times. In the same principle as the general cultivation of matcha and gyokuro, the tea leaves try to receive more sunlight in the cloudy weather, so they increase chlorophyll during photosynthesis.
Many other tea producing areas have relatively long daylight hours, so the tea leaves of Shimane have a brighter green color than the tea leaves of those producing areas.
It is believed that the most important point to manufacturing is how to retain the vividness of leaves. At Tousuien, the vivid green color is retained by instantaneous treatment with a small amount of steam and high-temperature hot air during “Sessai”(process that suppresses oxidation).

Izumo Brand Producers

All producers were born and raised in Shimane Prefecture.
“Making delicious matcha to make people satisfied”
That is the only thing they wish for, and they go to check the tea plantations every day regardless of rainy days or snowy days. Please enjoy their proud matcha made with great effort.

Tousuien’s Tea Master

A tea master Yuta Oka was born on September 15, 1987 in Hikawa-cho, Izumo City, Shimane Prefecture. He attended local elementary, junior high and high schools and after graduating from college he worked in the TV industry in Tokyo.
Having a unique background of working in the TV industry, Yuta has the creativity to see things from various perspectives, which is very useful for examining and discriminating tea.
He won the “SAN’IN* TEA TASTING CONTEST” at an unusual speed of just one year after getting a job in the tea industry. At a national competition he also had an excellent result, and achieved the brilliant feat of acquiring the 5th dan-i at the age of 28.
All Tousuien’s Izumo matcha is carefully examined by Yuta Oka.

The First Matcha in Izumo, Shimane

Even though the per capita consumption of matcha in Izumo area is at the top level in Japan, no matcha has ever been made in Shimane. Therefore, Tousuien embarked producing Shimane’s first matcha. They started the project by planting 433,700 tea trees all by hand in a vast tea plantation.

Tea trees suitable for the environment in the Izumo area will not grow with the way of cultivation in the textbooks. Tousuien has the own schedule management and thorough quality control, keeping in mind the environment for tea trees to grow vigorously.

Furthermore, they have changed the long-established method of “using lots of fertilizer”. They have designed fertilizers suitable for tea plant varieties, and soils in each field, and are focusing not only on nutrients but trace elements as well, and they are cultivating tea leaves in consideration of their color.

The Climate of Izumo Area

The Japan Sea side(Western coast) where Izumo City is located, has less rainfall and longer sunshine hours. Although it is a harsh environment where the temperature is high in the summer and deep in the snow in the winter, the tea trees have grown vigorously.

Processing of Izumo Matcha

This is a dedicated fire pit that is indispensable for making tencha, the raw material for Matcha. It is made of bricks and the temperature inside is raised up to 200℃ to process tea. The far-infrared rays emitted by bricks create a unique flavor of tea that cannot be obtained with other fire pits.

Various Certificates

It costs money to issue the certificates and documents following (exept the Tousuien’s original authentication document of being 100% Izumo Matcha).
If you would like the certificate and documents, please contact the person in charge.

Learn more about ASIAGAP

It complies with international standards and can be used for export. The number of control points is about twice that of JGAP, and the international standard for human rights and hygiene, “Hazard Analysis Critical Control Point (HACCP)”, etc. will be added.
GFSI (Global Food Safety Initiative) is an organization established in 2000 by major food companies operating globally, and is equivalent to a wide variety of food safety certification programs in the world. We are operating a program for planning. For food retailers and manufacturers, mainly in Europe and the United States, it is becoming a trading condition whether or not they have obtained this GFSI-approved certification.

Mythical land Izumo -“Legend of Yamata no Orochi”-

The exiled Takaamanohara (The heavenly sanctuary where the Japanese gods are enshrined.), Susanoo-no-Mikoto, descended to Torikami, upstream of the Hikawa River in Izumo.
When Susanoo-no-Mikoto visits the upper reaches of the river, there is an old man and an old woman, and a girl is crying between them.
The old man is Ashinazuchi, the old woman is his wife, and the girl is their daughter, Kushinadahime.
When Susanoo-no-Mikoto asked them why they were crying, the old man replied.
“There were eight of our daughters. However, Yamata no Orochi came every year and ate our daughter. That time has come again this year. That’s why we’re crying.”
Susanoo-no-Mikoto asked what the Yamata no Orochi looked like.
The old man said, “The eyes are red like a hozuki, and one body has eight heads and eight tails. The body has lycopodium clavatum, cypress, and cedar.
Its length is about eight valleys and eight peaks, and blood is always dripping on the belly. “
So Susanoo-no-Mikoto said to the old man. “I want to marry your daughter. I am the younger brother of Amaterasu Omikami, and for that reason I came down from Takaamanohara.”
The old couple said, “I am afraid of such a person. I will marry my daughter to you.”
Then, Susanoo-no-Mikoto magically turned the girl into a comb, stabbed her in his hair, and ordered the old couple to make strong sake, turn the fence, set up shelves, and put a sake tub for each shelf. And he made them pour the Sake.
When Susanoo-no-Mikoto was waiting, Yamata no Orochi came.
Yamata no Orochi thrust his head into each of the sake tubs, drank sake, and fell asleep with much drunkenness.
So, Susanoo-no-Mikoto unleashed a sword called Totsuka no tsurugi on his waist.
When Yamata no Orochi was torn apart, the Hikawa River flowed as a river of blood.
The blade of the sword spilled when he slashed the middle of the tail of Yamata no Orochi. He wondered, stabbed it with the tip of his sword, and a Tsumuha sword came out of his tail.
Susanoo-no-Mikoto thought that this sword was unusual and presented it to Amaterasu Omikami. This is Kusanagi sword.
After subduing Yamata no Orochi, Susanoo-no-Mikoto searched in Izumo for a place to build a palace. He came to a place called Suga and he was told, “I am here and my heart is refreshing,” and he built a palace there and lived there.
When Susanoo-no-Mikoto first built the Suga Palace, clouds rose from that area.
There he wrote a poem.

八雲立つ 出雲八重垣 妻籠みに 八重垣作る その八重垣を
(Translation of poetry: The clouds of Izumo that rise up like a magnificent fence. I will make a magnificent fence to protect my wife, that beautiful magnificent fence.)

When the palace around the fence was completed, the couple (Ashinazuchi and Tenazuchi) were invited.
Ashinazuchi was appointed as the secretary of the palace and named “Inada no miiyanushi suga no yatsumimi no Kami”.
