About

A day-use natural hot spring facility along the Minami-Tama ridgeline road, about a 22-minute walk from Tamasakai Station on the Keio Sagamihara Line (a local bus route is also an option). Four outdoor baths draw on a sodium bicarbonate-chloride cold mineral spring (hypotonic, weakly alkaline), alongside indoor baths that include a carbonated bath, a reclining bath, and a jet bath. The sauna area has two rooms - a dry sauna with automatic loyly and a mugwort-mud-salt sauna - plus a 90cm-deep cold plunge and an outdoor rest area. The second floor holds the Shunsaitei restaurant, rest areas including a co-working space, and massage chairs. Guests with tattoos, including cover stickers, are refused entry.
