Naganuma Goumeigaisha produces Soumura sake in Nagai City, Yamagata Prefecture, a region within the Tohoku area known for high-quality sake production made possible by cold winters and abundant snowmelt water. The brewery produces Soumura in several styles, including the Junmaishu Dewanosato made with local Dewa-no-sato rice, as well as small-batch junmai daiginjo editions whose labels have been illustrated by anime artists. The brewery also produces Kozakura Seisen, a refreshing, lightly sweet sake popular among local residents.
