About

The oldest sento in Izumi City, located near Izumi Shimizu Inoue Shrine where 'Izumi Shimizu' is enshrined. The bathing area is simple with stone-paved floors and only shallow bath, deep bath, and jet bath. The water is natural underground water heated with firewood in the traditional way, allowing you to truly feel the 'hot water'.
