Founded in 1892 by Yososaku Obata, this brewery has over 130 years of history. Their motto is the 'Four Treasures of Sado'—rice, water, people, and the island itself. Led by master brewer Kenya Kudo, they brew sake with care using traditional early morning methods. They use sake rice from Sado, such as Gohyakumangoku, and Niigata’s original Koshi Tanrei. Since 2014, they’ve been using a repurposed former school building as their brewery and are committed to sustainable sake production powered by renewable energy.
