The birthplace of Tadataka Ino — the man who created Japan’s first complete map through actual measurement — was a sake brewery in Sawara. The founder of Tokun Brewery is said to have apprenticed at the Ino family brewery before establishing his own. Since then, the brewery has thrived in the fertile Suigo region, blessed with pure water and early-harvest rice, crafting sake with the refined techniques of Nanbu Toji brewers. Renowned for its quality, Tokun Brewery has received numerous awards at sake competitions and continues to be celebrated both locally and across Japan.
