Miyasaka Brewery Co., Ltd. was founded in 1662. It all began with Ihei Arimasa Miyasaka, the 12th head of the Miyasaka family, who started a brewery at the city of Kamisuwa, Nagano, Japan. For the next 300 years, Miyasaka spent tremendous amounts of time to create a perfect sake “Masumi,” which today is highly regarded for its aroma, body, and rich taste. One of the secrets of this popularity lies in the company’s successful development of a special high-quality yeast.
