The room was decent, but the facilities need improvement. There are only 2 big slides, and you have to pay for both of them. For each time you want to go on the slide, you have to pay 500 yen. You can buy an all-day pass for 1500 yen. If the weight difference between you and your partner is too big (30-40 kg), then you cannot go on the slides. We came around 5 pm, and there were no lights as they were all turned off. The earliest you are allowed to check in is 3pm, and the time you take to get to your room and check in and change would probably get you to the park by 5pm. There is no problem with this, except for the fact that the slides close at 6 pm. For the kids section, it is just a small splash pad with 2 small slides which were free, but if you wanted to go on the other kiddy slides (about 3 of them), then you would have to pay an extra 800 yen. I think there was an outdoor pool, but you had to pay an extra fee to use that as well. The oden pool was ok, but there are some safety concerns. On the advertisements, it shows a woman sitting on one of the oden pool floaties, which will make everyone want to try to hop on the tall floaties and sit on them. All around the oden pool, there are stairs underneath the water, which, if someone falls, can lead to a concussion, bleeding or more. Another note on the water slides, you cannot ride alone, and can only ride with 1-2 people. The check-in was really slow. Overall, if you do not like paying extra for everything, don't come
