Yamato Soysauce & Miso Co. Ltd

Yamato Soy Sauce & Miso (ヤマト醤油味噌) is a traditional Japanese fermented food manufacturer based in the Ono district of Kanazawa City, Ishikawa Prefecture. The company specializes in the production of soy sauce, miso, fish sauce (ishiru), and a wide range of related fermented products, including amazake (rice malt drink), shio koji (salt koji), ponzu, and gluten-free organic soy sauce. Rooted in the historic koji-making traditions of the Kanazawa Ono region, Yamato upholds time-honored methods such as wooden barrel fermentation and natural brewing to deliver authentic, high-quality flavors.

The company operates the Yamato Koji Park (ヤマト・糀パーク), a dedicated visitor facility where guests can experience the world of fermentation firsthand through tours, hands-on workshops, and dining at the in-house Fermented Food Beauty Dining restaurant (発酵食美人食堂®). Yamato also cultivates a community of fermentation enthusiasts through its 'Koji Club' (糀部) and the Fermented Food University, reflecting its commitment to promoting a healthy, fermentation-based lifestyle under the philosophy of 'Ichiju Issai ni Ichi Koji' — one soup, one dish, one koji.

Positioned as a premium artisan producer in the Japanese fermented foods market, Yamato blends cultural heritage with modern wellness values, offering both retail and wholesale products alongside unique branded lines such as 'Magohayasashiiko®' and 'Kome to Hana.' The company actively engages in sustainability initiatives, regional food culture promotion, and e-commerce, making its distinctive Kanazawa-style fermented products accessible to customers across Japan.
