Sawasa Shuzou was established in 1793 in Nabari City, Mie Prefecture, and has maintained a stubbornly careful sake-brewing policy across more than two centuries of operation. The brewery is led by Shigehisa Sawa, who serves as both owner and toji, keeping production tightly under family stewardship. Sanguu is the brewery's flagship brand, representing a commitment to unhurried, meticulous craftsmanship rooted in the landscape of Mie.
