About

An adult day-spa facility a 2-3 minute walk from Toshimaen Station (Seibu Ikebukuro Line, Toei Oedo Line, Seibu Yurakucho Line), overlooking a roughly 1,200-tsubo Japanese garden designed by landscape architect Kenzo Ogata. It draws an iodine-sodium chloride strong brine spring from 1,445m underground, and offers a swimsuit-required bade zone with an outdoor jacuzzi, a Finnish sauna with an auto-loyly stove, an outdoor Finnish sauna, and a steam sauna. It also has a ganban'yoku bedrock bath, the "Ryokusuitei" restaurant, and relaxation tenants offering body care, esthetic treatments, and head spa. There is no parking, so guests are expected to arrive by public transit. Guests with tattoos, including covered ones, are not admitted. Entry is restricted to age 13 and up, and junior/senior-high students generally need a guardian.
