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).

Low-pesticide Cultivation

A major factor in the start of low-pesticide-cultivated matcha was that before Tousuien’s foundation(March 2006) they believed that overseas demand of matcha would increase and then low-pesticide cultivation should be essential for making Izumo Matcha’s debut to the world.
Low-pesticide cultivation has the disadvantage of increasing the probability of outbreaking of pests, but their tea leaves are cultivated in a near‐natural environment to minimize the strain on the tea plant as possible, for maximizing its bright green color. As a result, they are confident that they are cultivating more beautiful green tea leaves than other production areas.
Also, the fields are directly connected to the firefly conservation area, and the water and soil are very clean.
In the beautiful nature of Izumo, Tousuien is making matcha that can only be made here while considering the environment.

The First Matcha in Izumo

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.
