A matcha company in Tokyo, built for wholesale. We source 100% Japanese-grown matcha from certified mills in every producing region and ship it to cafés, brands and importers worldwide from Osaka.
Founder and CEO. Grows tea in Minamiyamashiro, leads sourcing at the mills and works directly with every wholesale account. Half Japanese, half Trinidadian, UCLA. Two million views on @junpeitalks in its first five months.
Alexis Junpei Sato founded ULUHASHI Inc. in Tokyo and runs ISSA MATCHA!, its matcha business: a tea field in Minamiyamashiro, Kyoto, partner mills across Japan, wholesale, retail and the café pop-ups. Half Japanese and half Trinidadian, he studied International Development Studies at UCLA before coming back to Japan, and built the company around a contradiction he could not stop noticing: the world was falling in love with matcha while the farms that grow it were closing at a rate of more than a thousand a year.
He spends the harvest months in the tea regions, at the mills in Yame, Kagoshima and Shizuoka that produce our lots, and the rest of the year with the cafés and brands that pour them. Every product in the catalog is one he has cupped at the mill, and the company's one rule, 100 percent Japanese-grown with no overseas blends, is his.
On @junpeitalks he covers the matcha trade in plain language: what first-harvest leaf actually costs, which labels mean nothing, and which villages are losing their growers. The account passed two million views in its first five months, with long-form interviews with mill owners and café founders in Japan and Thailand. In summer 2026 ISSA MATCHA! ran a two-month pop-up at SO TARTE in Omotesando, Tokyo, which Time Out Tokyo picked as one of four things to try in the city that summer.
Wholesale enquiries are handled by Junpei and the sales team in English and Japanese. Samples ship within three business days and quotes go back within one.
@junpeitalks is where our founder says the uncomfortable things about the matcha trade: labels that mean nothing, the farms that are disappearing, what first-harvest leaf really costs. The most-watched ones, below.
