We went there just yesterday, I'll evaluate both places, pool area and onsen area. It was a Sunday and day before a national holiday, so quite crowded, as others mentioned 3.500 yen seems a little high because although the pool area is quite big with many pools it was very crowded and noisy so we couldn't enjoy it too much outside. I think it's nice for families but couples should come under the week. Onsen area on the other hand was beautiful, I like the differencet temperatures and it looked newly built. I didn't notice anything too dirty, so I can't understand the negative ratings to be honest. Overall 4/5 recommended on the weekend, would like to come again under the week 😊 Resting area is nice too! Also recommend eating outside because it's cold for sure if we go from bath to bath so I can't imagine sitting there. Recommendation: create a space with heaters.

I'm not sure why I expected more out of this place but it's very geared towards kids and instagrammers. That part doesn't bother me as much as none of the water features indoors are even hot. They're all lukewarm. When you're used to going to spas that have varying temperature water features. This was a huge disappointment. Also be prepared. The staff speaks literally almost no English and couldn't even read the translator apps. Didn't feel like they wanted non-residents to even come to the establishment. I booked a private room online and when I got there they told me they were all closed even though other people were using them.

I felt like the attendant had a bad attitude when I checked in. The first thing they did was rudely tell me I could get towel with my hotel voucher but next time I would need to pay, and understand what she might have been trying to tell me but the way she said it struck me as being unprofessional. I mentioned I didn't have a bathing suit so they said I could just use the onsen which is what I wanted to do anyways, what they didn't tell me is the onsen only opens at 11am, it was 10:15, like why hold back what is contextually valuable information so I don't waste both our times checking-in in the first place.

Pretty kitschy kind of place for the main waterpark but it was fun to see the different themed areas. Was pretty good for our younger kids but I don’t think teenagers would have as much fun…. The traditional onsen area was much nicer but families have to split up and go by gender , kids are allowed there as well ( younger than 6 can go with either parent I think). Worth half a day if you’re looking for a way to have some fun with younger kids and do a traditional onsen

Gross! We visited the swimsuit pool area as visitors, did not stay at the hotel. It was crammed full of people. Some surfaces were slippery and almost all areas except the rest area upstairs were not clean. Locker rooms were slimy and dirty. If youre from the U.S. and know Great Wolf Lodge, it was like that but worse. The staff at the front were very nice, that was about the only good thing about it. We didnt stay long, even the kids were grossed out.
