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.

Children pay ¥450 on Saturdays, Sundays and holidays. A weekday late-night discount (entry after 22:00) brings the adult rate to ¥750.

The ganbanyoku stone-bath rooms (Kama-no-fusa and Iwa-no-fusa, free-time system, rental wear and mat included, junior-high age and up) carry an extra charge, but the official site is inconsistent (the ganbanyoku page says ¥600 on weekdays and ¥650 on weekends/holidays/designated days; the admission-guide page says ¥700 and ¥750). A 10-visit coupon book costs ¥7,900 on weekdays and ¥8,700 on weekends/holidays.
