Our Story

   The history of 1200 years and the mission of ZENJIRO   

ZENJIRO
ZENJIRO (禅地朗) is our title of tea master blender and our Yago (its meaning "house and/or studio name" applied in traditional Japanese culture).

ZENJIRO is named after both the current place name OZENJI and the OZENJI temple, built by the ancient Emperor in 757 AD. This OZENJI temple was one of the oldest groups that drank tea 1200 years ago. Surprisingly it was prior era 700 years to the tea master Sen no Rikyu who established the tea ceremony style.

The founder ZENJIRO (Michio), who is a descent of two ancient samurai commander family’s lineage, has spent a long time in the finance and IT industries. One day, he researched old history about Japanese green tea, and was impressed by the fact that green tea was used as a medicine. He visited various production areas of the high-quality green tea and finally reached the current terroir. The tea garden at this place was also exceptional.

Our Criteria
Japanese green tea is itself a bounty created by the earth. Japanese tea tree that grows only in a narrow range of 30 to 36 degrees north latitude. Olives are also trees that bring good health, but tea trees need the opposite climate. That is, it requires sufficient precipitation and slightly acidic soil. Indeed, there are not many cities around the world located in this north latitude. There are cities in China that cover several latitude ranges, but the type of tea tree is different. Japanese tea tree is cultivated with proprietary seeds thanks to breeding efforts.

ZENJIRO seeks finest soft tea leaves that are rich in the relaxing ingredient theanine (a kind of protein). As a result, we exclude the flat tea leaves plantation area close to the sea from our target because sunlight is too strong and theanine changes to catechin naturally and leaves become stiff.

The Terroir
Our tea leaves are produced at Mino Shirakawa, the northern limit of Japanese tea cultivation. This place is exceptional. There is a common relationship between the cultivation conditions for Japanese tea and the cultivation conditions for fine incense woods that have supported traditional Japanese architecture. The place where hardwood and coniferous coexist, with an altitude of around 800m, good drainage and moderate humidity. The cypress grown under this special natural condition was wood historically delivered only to the emperor's residence, shrine, and generals of the Edo period.

Mino Shirakawa's tea leaves are very small in production, and farmers cultivate tea trees with overcoming obstacles on steep slopes, pruning and maintaining soil. However, natural climatic conditions benefit their efforts. Fog rising from the river at the foot of the mountain blocks excessive sunlight and creates soft and fragrant tea leaves. By growing slowly in the northern limit, abundant proteins such as theanine are accumulated. People call these tea leaves a natural Gyokuro.

Artistic Tea Blending
ZENJIRO creates our proprietary branded tea products collaborating with tea masters of the production area. The conductor of the orchestra is ZENJIRO, but sometimes plays musical instruments by ourselves.

Our mission is to choose the best tea leaves, to design products that can extract the best ingredients as efficiently as possible, and to blend them according to the purpose of the products. We do not hesitate to repeat this careful process over time and do not save time in order to make the best products.

Our Quality Standards
Green tea is fundamentally different from black tea and Chinese tea. By stopping the fermentation by heat treatment, components such as theanine and catechin are maintained without alteration. The biggest enemy of Japanese green tea is oxidation. For this reason, we do not sell tea leaves in classic tea tubes or tea boxes. Tea bag type products use air-blocking material rather than paper envelopes. It is better to consume quickly after opening, but the ingredient quality is maintained for a long time in an unopened state. Don't give up even after the expiration date. The scent is reduced, but the ingredients remain the same. Unlike black tea and Chinese tea, Japanese green tea has a weak fragrance, but rather for enjoying its ingredients.

We have been making many small innovations in the details of the relationship between tea bags and packaging and tea leaves as well. There is a view that cutting the finest tea leaves finely is crazy. But we don't hesitate to do it for the purpose to deliver the best value to our customers.

Our Matcha
Ingredients such as theanine and catechin are water soluble and account for 20-30%. However, water-insoluble ingredients also contain ingredients that are good for health. Chlorophyll, vitamin E, beta-carotene, CoQ10, etc. It is effective to pulverize them for efficient consumption. Matcha and powdered green tea are reasonable methods from the meaning.

In particular, Matcha is a gift from traditional craftsmen. We selected carefully Matcha territory and chose Uji Matcha. Matcha is used for traditional tea ceremony, but the tea ceremony itself is out of our scope.
