Health-oriented tea KOHEI is an organic green tea grown and processed by Takahashi san in Oita to increase its levels of GABA (gamma-aminobutyric acid), a natural component of green tea.

GABA is an inhibitory neurotransmitter also found in human bodies. Its main role is to reduce neuronal excitability. Research has shown that GABA contributes to preventing high blood pressure, helps with sleep disorders, and reduces stress and anxiety.
Thanks to the combination of GABA with other healthy nutrients specific to tea such as l-theanine and other polyphenols, GABA-rich tea has a deeper impact than regular green tea on chronic stress-induced autonomic imbalance, and related risks for cardiovascular disease (see examples of recent studies published here, here and here).
Grown by the producer of our super popular KOJI and KOTARO tamaryokucha, KOHEI greets you with a delicious gingerbread aroma when you first open its bag. Its beautiful pale golden liquor is sweet, refreshing, easy to drink, with hints of cinnamon and citrus notes and leaves a pleasant bitterness on the tongue. Its positive impact on sleep disorders and low levels of caffeine make it a great late afternoon or early evening tea.
Our team fell in love with the cute design of KOHEI's original bag made by Takahashi san and decided to keep it as it is. The drawing represents Takahashi san and his mother who leads family business alongside him, and was based on this photography (see in the picture gallery).

Tasting Guide

Aromatic Profiles


Established in 1963, the Takahashi green tea factory is located in Usuki (Oita pref., Eastern Kyushu) and produces organic green tea since 2001. It was the first green tea farm in Oita to receive the organic JAS certification in 2001.

Takahashi san is now the second generation of his family to lead his business and is specialized in tamaryokucha, a green tea known for its jade color (tama), quite similar to sencha, but whose leaves have a curly shape, and not needle-like. The very last stage of the processing method is different: the tea leaves are put inside drums and dried with hot air.

Takahashi san grows seven different tea cultivars, mainly Yabukita.

Delightful tea. Sweet and herbaceous on the nose lead way to toasted graham with slight grassy tones.

Great tea

I noticed IKKYU tea during recent visit to Tokyo where my host serviced varieties of tea produced by IKKYU during my four days stay. Every tea is individual and has a great taste, I love them. I bought them on line and received them in three days in Hong Kong. Great tea, Great services!

A dabba GABA

This is my go to tea especially on days when I’m feeling a bit sluggish. It has a wonderful taste, yields several infusions and does seem to deliver a bit of extra happiness.

Kohei "GABA" Green Tea

This tea is probably an acquired taste - I found it rather grassy in a musty way. On a positive note, it was much more palatable when I had it cold. The packaging is cute!
