We used the campsite. It was a lakeside campsite built on the mountainside, but the first downside was that there were only two toilets compared to the vastness of the site. I thought it would be a better campsite if they could improve it. I only had one night to sleep in, so after careful consideration, I decided on a free site booth that would have been the first to be built.It was the closest to the hotel and had Japanese-style toilets, one for men and one for men.There was an old-style kitchen. I went there. It was quiet with no other users besides us, but there was an administration building that was probably used in the past, and the curtains were half open, so it was kind of creepy when I saw it at night lol.Other than that, there are no restrooms unless you go to the top of the mountain, and I think the car site cost 4,000 yen per night. The toilet there looked new. There is a new kitchen on the way up there, but either way it's far from the restrooms and it's a mountain so it's difficult to climb up and down, so it's not that far. It's not possible unless you go there by car. I also went to look at car sites, but they are very inconvenient except for those near the restrooms. It's either far from the kitchen or far from the toilet. Maybe it was created by someone who has never been camped before? It is made in a way that makes you think. By the way, on the day I stayed, it rained on and off, so I had dinner under the roof of the kitchen. (The kitchen is spacious and could fit a small tent haha. That might be the only good thing haha) I got bitten by mosquitoes 20 times in about an hour haha. I had a terrible experience lol. Be careful of bush mosquitoes. Insect spray is required.I might visit again once the toilet issue is resolved lol.The environment was quiet and the cleaning was thorough. I think that can be appreciated. At that time, the administration building was closed, so looking at other people's comments, it appears that there is a toilet in the administration building. It might be better when the administration building is open.
