Ookunishuzo was founded in 1898 and is located in Ina City, Nagano Prefecture, drawing brewing water from a well sunk 80 meters into the ground to reach the Central Alps aquifer. The brewery has maintained its core brands Ookuni and Hyoga since its founding, and its Hyoga 30 expression — at 30% alcohol — stands as one of the distinctively high-proof offerings in the Japanese sake landscape.
