Grand Green Osaka, Umeda, Osaka
Umekita Onsen Ren Wellbeing Park
A full-service option beside Osaka Station if you will use the sauna, rest areas, fitness facilities or pools. For a quick soak, use the 60-minute bath-only ticket rather than paying for a longer stay you will not use.

- Opening hours
- The whole facility has operated 24 hours since March 21, 2026, with separate daily cleaning windows for the men's and women's large baths. Bath-only entry is ¥1,650 for up to 60 minutes; basic packages start at ¥3,190 on weekdays and ¥3,740 on weekends and public holidays. Staying beyond 12 hours adds ¥2,970. Some anniversary dates had a late-night fee promotion; do not treat it as permanent pricing.
