Tateyama Yoshimine Onsen Yū-Land (Green Park Yoshimine)
A town-run day spa inside the hilly 'Toyama Forest of Health – Green Park Yoshimine', about 15 minutes by car from Tateyama Station, the Toyama gateway to the Tateyama-Kurobe Alpine Route. The clear, mildly alkaline simple spring is piped straight from the source and called 'beauty water'; besides the main bath there is a rustic rock open-air bath, an herbal bath and a sauna. From April 2026 adults pay ¥750 and children ¥380; open 10:00–21:00 (last entry 20:30), closed Tuesdays (plus maintenance days). The park has a campsite, barbecue area, park golf and the Yoshimine Heights lodge, making it a handy stop before or after the Alpine Route or a Tateyama climb. About 5 minutes by car from Iwakuraji Station (Toyama Chihō Railway), 20 minutes from Tateyama IC; 300 parking spaces.
