Founded in 1899, Hato Masamune Brewery’s flagship brand, Hatomasamune, has a rich history. It was originally named Inaoe Masamune after the nearby Inaoe River, but later changed to Hato Masamune in honor of the white doves that made the brewery their home, believed to be protective spirits. Located in the nature-rich city of Towada, Aomori, Hato Masamune uses pure spring water from the Hakkōda and Oirase regions for brewing. The sake is crafted primarily with locally grown Aomori rice varieties, such as Hanaomoi and Hanafubuki.
