About
A day-spa in Itabashi Ward, an 8-minute walk from Exit A2 of Shimura-Sakaue Station (Toei Mita Line), with 74 free parking spaces. Its "Gensen-buro" offers an unheated, unfiltered, additive-free flow of an iodine-sodium chloride strong brine spring at a 32.7°C source temperature, alongside a filtered/circulated outdoor bath, a high-concentration carbonated bath, a hyper-jet bath, a reclining bath, a sitting bath, and a cold bath. The sauna consists of a tower-style dry sauna for men and women and a women-only herbal salt steam sauna, both limited to junior-high age and up. It also has a ganban'yoku bedrock bath (junior-high age and up, +¥760), a private charter bath ("Akari"), a restaurant ("Kakitensha") rebuilt from an old farmhouse, a rest area ("Utatane-dokoro") including a women-only room, massage/esthetic/aromatherapy treatment rooms, and a Japanese garden. Guests with tattoos may enter only if fully covered with the facility's designated cover seals (11cm x 20cm, up to 2 sheets). Towels and roomwear are separate rentals at ¥380 each.
