About

A traditional miya-zukuri (shrine-style) bathhouse in Shimouma, Setagaya, with a Mt. Fuji penki-e wall painting and an ultrasonic jet bath. The water runs on the hot side, and a free wet sauna is available. After the bath, guests can relax while looking out over the well-kept garden. About a 10-minute walk from Sangenjaya Station on the Tokyu Den-en-toshi Line.
