About

A day-use bathhouse inside Hankyu Oimachi Garden, 2–3 minutes on foot from Oimachi Station (JR Keihin-Tohoku Line, Tokyu Oimachi Line, Tokyo Rinkai Line). Baths include an artificial hot-spring bath, a high-concentration carbonated bath, a jet bath, a lying bath, and a silk bath, alongside two sauna rooms (Kings Sauna and a Chinese-herbal steam room) and "Honoo no Ma," a stone-sauna bath combining projection mapping with a heat-wave performance. The building also houses the restaurant "Tenpu," body-care/akasuri/esthetic relaxation services, and parking for 220 vehicles. Open 9:30–08:30 the next day (no new entry 01:00–06:30), year-round. Guests with tattoos are not admitted.
