Founded 400 years ago, Tsukasabotan Sake Brewery Co. is the oldest existing company in Kochi Prefecture. It has always been a favorite drink of many great people. The sake is clean and dry, as is typical of Tosa sake, but has a lingering aftertaste that lingers for a long time. The soft water of the Niyodo River system that is used for brewing brings out the best in this sake.
