About
Miyasaka Brewing in Suwa creates the renowned Masumi brand. The brewery's discovery of Kyokai No. 7 yeast in 1946 — now the most widely used sake yeast in Japan — revolutionized the entire industry. Drawing water from the pristine Kirigamine highland springs, Masumi produces balanced, aromatic sakes that showcase Nagano's alpine character.
