About
A day-use natural hot spring in Aiharamachi, Machida, reached by free shuttle bus from the south exits of Hashimoto Station (Keio/JR) and Hachioji Station (JR), and from Minami-Osawa Station (Keio Sagamihara Line). The source-fed spring water (drawn from 1,381m underground, a sodium chloride-bicarbonate spring) supplies two alternating bathing areas, "Sa-raku" and "U-raku" (swapped daily between men and women), each with its own outdoor bath, indoor bath, and sauna. Across both areas there are 11 baths in total, including four sauna types (salt, auto-löyly steam, basic dry, and radium stone) and two well-water cold baths. Other amenities include ganbanyoku stone-bath rooms (free-time system), the "SPA Re.Ra.Ku" relaxation service, a cafe ("Sakura") and a Japanese restaurant ("Take"), and rest areas including a comic room with about 10,000 volumes, karaoke rooms, and a kids' room. Open 9:00-24:00 Monday through Thursday and 6:30-24:00 Friday through Sunday (last entry 23:30). Guests with tattoos or tattoo stickers of any size are refused entry.
