About
A one-minute walk from Oimachi Station, this dedicated sauna facility with an attached capsule hotel opened in June 2024. It offers two sauna rooms, KUU and ZEN, and three cold plunge pools -- Little Mermaid, Single, and a numbing-cold recliner pool. The rooftop has an open-air bath and a Shigaraki-ware tsubo bath alongside an outdoor rest area, while an indoor lounge called "Night on the Planet" provides an alternative cool-down space. It is open from early morning 5:30 to late night 2:30 (last entry 1:00 AM). Pricing is tiered by duration, starting from 980 yen for 60 minutes on weekdays and 1,280 yen on weekends and holidays. Towel sets and loungewear are paid rentals for day guests (free for overnight guests). Payment is handled via wristband IC tag, and the entire facility is smoke-free. Ladies Day events are held occasionally. Guests with tattoos are not permitted to use the facility.
