Founded in 1804 as a kojiya (malt house), Aiyu Shuzo in Ibaraki Prefecture carries on the tradition of sake brewing through generations, starting from the koji-making craft. Under the spirit of "Shikai Kyodai", meaning "All Under Heaven are Brothers," we believe that sharing sake fosters unity among people worldwide. Nurtured by Lake Kitaura and Lake Kasumigaura, our sake is crafted with dedication, emphasizing the water and rice born from the region's rich soil. Each bottle embodies our pride in our craft! With a desire to enrich the hearts of sake enthusiasts, we strive daily to perfect our brews and share the allure of local sake with the world.
