Kaga Corporation (or Kaga Kensetsu), founded in 1943 in Kanazawa, the capital of Ishikawa Prefecture, was originally a construction company specializing in local infrastructure, particularly maritime projects. Recognizing that preserving a region means protecting its cultural heritage and communities as much as its infrastructure, the company decided in 2020 to diversify by launching a business dedicated to bōcha (roasted stem tea). In fact, bōcha is an integral part of Ishikawa Prefecture’s culture, a true cradle of tea culture with more than 120 years of history. Thanks to a patented superheated steam roasting technology, their teas retain rich and refined aromas. Quality is at the heart of their production: the stems are sourced exclusively from tencha (the raw material for matcha, unlike classic bocha which generally uses sencha stems), and all ingredients are JAS and Rainforest Alliance certified organic. Kaga Corporation is committed to promoting this traditional tea, a symbol of Ishikawa, throughout Japan and the world.
