SPA&SAUNA 水春 服部緑地
A premium bathing facility that finally opened on June 5, 2026 inside Hattori Ryokuchi park in Toyonaka, Osaka. The third-floor spa, wrapped in park greenery, offers open-air baths that feel like a mountain onsen inn, and its rock bath uses natural radon water - a rarity in Osaka Prefecture. Three saunas (with loyly), five themed rock-bath rooms, a premium lounge and even fitness complete the lineup. From 1,540 yen for a 90-minute adult session (1,980 yen on weekends and holidays), with rental towel, bath towel, loungewear and premium lounge access included. Open 9:00-25:00 on weekdays and from 6:00 on weekends and holidays, welcoming early-morning sauna fans. A 75-yen onsen tax is charged separately; rock baths are an extra 880 yen and up.
