Founded 350 years ago, Daiichi Shuzo is the oldest brewery in Tochigi Prefecture. Since its inception, the brewery has also been a farming family, handling everything from planting to harvesting in their fields. They use their rice varieties such as Omachi, Gohyakumangoku, Yamada Nishiki from Hyogo, and Miyama Nishiki from Nagano. The brewing water is high-quality, selected as one of Japan's 100 best waters. Daiichi Shuzo's flagship daiginjo sake, 'Kaika,' is a popular souvenir from Tochigi and enjoys nationwide popularity.
