OUR MISSION

Connect Heritage Matcha with the world

Everything with Intent

Fresh Ground

All Ooika Matcha is traditionally stone-milled in the USA. While labor intensive, producing only 30 grams of Matcha per hour, the freshness is unmistakable.
Single Origin

We celebrate single-cultivar, single-vintage Matcha, rather than blends, letting you experience each local microclimate from afar.
Directly Sourced

Our unground Matcha (known as Tencha) is directly sourced from famous and historic terroirs of Japan including Uji, Yame, Hoshinomura, Shizuoka, Kagoshima, and more.
Preserving Heritage

Our focus is on rare, heritage Matcha. Over 95% of tea in Japan is machine harvested—we prefer the 5% that is traditionally handpicked (Tezumi) or reed-shaded (Hozusaibai.)
Intentional Curation

We curate an ever-changing collection of Matcha from different terroirs, farmers, cultivars, and vintages to give you a breath of teas to experience and learn from.
Unrivaled Clarity

We provide the highest level of sourcing details in the industry so you can truly understand both the Matcha and the farmers who produce it.

Reducing Strain on the Japanese Tea Industry.

The global “Matcha Boom” has authentic Matcha difficult to find, even in Japan. It’s not just Western buyers that are affected, but the Japanese tea ceremony schools (Chanoyu) that have preserved Japan’s tea tradition for centuries. The ethics of this are a hotly debated topic.

Shockingly, the shortage isn’t simply a lack of Tencha (unground Matcha) bur rather the lack of capacity to grind the Tencha into Matcha.

Many Japanese producers have the Tencha, but struggle to keep stock due to stone mills only producing about 30 grams of matcha per hour, creating a severe bottleneck.

Infact, Uji Matcha manufactures have said, “Limited sales to the general public in order to prioritize supply to its long-time customers such as tea ceremony practitioners and shrine affiliates.”

Ooika is the largest Shiagecha refinery in the U.S., milling Japanese Tencha entirely in-house. By refining abroad, we reduce strain on Japan’s limited stone mills—ensuring more matcha stays in Japan for cultural and ceremonial use, while still returning capital to the farmers who grow Tencha.

making matcha accessible

To preserve Matcha, Matcha must be appreciation. To be appreciated, Matcha must be understood. Ooika takes a contemporary approach to Matcha education, sharing the stories and knowledge we learn from multi-generational tea farmers across Japan.
