Akuarizoto Kiyosatotennyono Hot Spring

Located within Kiyosato Hill Park, the hot spring is located on the second floor of the building. There's a play area called "Children's Paradise Square" on the first floor, and a kids' cafe on the third floor, making it a convenient location for families with children. The hot spring is open from 10:00 to 21:00. The second floor, where the front desk is located, has massage chairs, a small snack corner, and gachapon machines, making it the perfect place to relax after a bath. The freezer next to the shop had a wide selection of Chateraise ice creams. Prices start at around 100 yen, so I saw many people enjoying them after their bath. There's also a wide selection of drinks, including classic sports drinks and teas. This is the perfect spot for a relaxing bath while letting your kids play in the Kiyosato area. The parking lot is spacious and easy to park.

When it was previously operated as "Tennyo no Yu," I would stop by on my way home from camping. I recently visited because they were having a New Year's event, but the management has changed and things have changed quite a bit, so I'm recording it here. I'm not sure if it's just during the event, but if you use the entire facility, the children's rate is almost the same as the adult rate (see photo). I also used the cafeteria, and even though I ordered tempura udon and ramen, they put a boiled egg in my ramen; the management is a complete mess. You are required to take off your shoes and move around barefoot in socks inside the facility, but the elevator and staircase areas seemed like they hadn't been cleaned, as they were very dusty and made me want to wear slippers. The hot spring itself was fine, so I gave it two stars.

Tennyo no Yu was its previous name; it's now called Kiyosato Natural Hot Spring. It has an old-fashioned feel, and since I visited on a weekday afternoon, the only good thing was that it wasn't crowded. Although it's a natural hot spring, it smelled like a swimming pool, suggesting chlorine disinfection. There's an indoor and an outdoor bath; the indoor bath was a decent temperature, but the outdoor bath was lukewarm. Aqua Resort was also likely its previous name. Now, the indoor pool area no longer has water and has been converted into a playground with toys. Adults pay 850 yen. It's not very cost-effective, but it might be worth it after skiing in the winter.

Use of Children's Paradise SOPO Went on a Sunday. A 5-year-old. The price includes the hot spring. Towels not provided. No time limit. No re-entry allowed. We had the place almost to ourselves. The play area looked newly built and was clean. It appears to have been a former pool, with traces of that still remaining in places. The play area had a unique smell. Like paint or damp. It might be difficult for those sensitive to smells. There were lots of toys and areas for the kids to play in, so it looked like they had fun. We could probably spend about 3-4 hours there.

I go there a few times a year. Like other reviews have said, the facilities feel a little old, but I like it because you can relax in the natural hot springs. There's an indoor bath, an open-air bath, a sauna, and a cold bath, so you can enjoy everything, and the open-air bath is surrounded by forest, so you're surrounded by trees and birds, which has a very relaxing effect. There's also a "Children's Paradise Square" where children can play, so I think it would be fun for couples to take turns soaking in the hot springs.
