by Oishi Chaen株式会社 大石茶園
A single-cultivar ceremonial matcha made from 100% Okumidori tencha grown in Yame, Fukuoka. Harvested once a year during the first spring flush, the leaves are shade-grown and stone-milled to produce a powder with a signature emerald-green colour. Okumidori's late-maturing nature allows a longer accumulation of amino acids, yielding elegant sweetness, a silky mouthfeel, and minimal bitterness. Gold Prize at the Japanese Tea Selection Paris 2025 and two-star Great Taste Award 2023.
Editorial verdict
The standout offering from Oishi Chaen's Ochamura line — a beautifully clean, sweet Okumidori that punches well above its price. Award-winning quality from Yame's most respected wholesale producer.

About the brand
株式会社 大石茶園
Oishi Chaen (株式会社 大石茶園, OISHI TEA FACTORY) is a long-established Yame tea manufacturer founded on April 1, 1940 by Oishi Mitsuyoshi in Murotaoka, Yame City, Fukuoka Prefecture. Now led by third-generation owner Oishi Goji (大石剛司), the company has grown from a local producer into one of Yame's major wholesale tea manufacturers with capital of ¥50 million. In 1954 Kenji Oishi took over management, and the company was renamed in 1972. A landmark came in 1977 when Oishi Chaen won the Japan Agricultural Minister's Award for gyokuro quality. In 1991 they established a retail subsidiary, 株式会社お茶村 (Ochamura), to reach consumers directly. The company invested in CCD optical sorting systems in 2008 and achieved FSSC22000 food safety certification and JAS Organic certification in 2018. Oishi Chaen exports its Yame matcha and gyokuro to over 40 countries worldwide. Their matcha is described as a rich, well-balanced blend of umami from Yame tencha, crafted for a mellow and blissful cup.
