Ooika preserves Japanese heritage Matcha by milling it fresh in the United States. Ooika is the largest Matcha refinery in the country and one of the only operations running authentic Ishi-Usu (石臼) stone mills at full scale.
We source single-origin Tencha directly from award-winning farmers in regions like Uji, Yame, Hoshinomura, Shizuoka, and Kagoshima, ship it shelf-stable, and mill 100% of it in-house, daily.
We run high-volume specialty cafes serving a full menu milled fresh every morning, sell single-origin retail Matcha with the mill-date printed on it, and operate Honzu, our made-to-order onigiri concept that supports the same rice-straw farmers who shade our tea.
Ooika approaches Matcha like fine wine or specialty coffee, and we publish more about our sourcing than any Matcha company in the world: cultivar, vintage, shading duration and method, milling details, terroir, and the farmers themselves, with photos and video from the farm.
