Matsuzakari is produced by Okabe Gomei Gaisha, a brewery established in 1875 in Hitachiota, Ibaraki Prefecture, drawing water from the nearby Satogawa River, prized for its low iron content and clarity. The brewery's guiding principle is that sake is a living thing, and their commitment to utmost diligence has earned the Matsuzakari brand 12 gold prizes at the Annual Japan Sake Awards since 1998.
