Crafted in the historic town of Ōta in Gunma Prefecture, Shimaoka Shuzo has been brewing sake since 1863, helmed today by toji Toshinori Shimaoka. Revered for their steadfast adherence to traditional methods, the brewery specializes in the labor-intensive yamahai style, resulting in sake of deep character and layered umami. Gunma Izumi Honjozo is a benchmark expression—robust, earthy, and soulful—with a style that embraces complexity over polish.
