If you go about 2km on National Route 222 past the roadside station Sakatani, there will be a narrow road on your left that leads down to the campsite. There is a parking lot about 100 meters away, and beyond that is the largest tent site, which was probably the playground of an elementary school in the past. As you go up the stairs, you will see an administration building, a courtyard (you can also pitch a tent here), a gymnasium, a parking lot in the back, and a building with bathrooms. There is a river right next to it, so it seems like you can pitch a tent in the area facing the river. Perhaps because it was a Saturday and Sunday, cars were not allowed to enter the tent site in the schoolyard. You can only enter when loading and unloading luggage. Although the bath is for cottage guests, those with tents can also use the shower. You can use it for 100 yen if you apply at the reception. There seems to be no time or number of restrictions. There are power outlets outside the administration building and in the kitchen, and you will need to pay 310 yen to use them. The lawn is well managed. The pegs fit in with no problem. The site toilets are simple flush, and those in the administration building are flush. Cleaning is considered to be thorough. You can hear the sounds of trucks and motorcycle gangs passing by right next to the national highway, but it's hidden by the cedar forest and doesn't really spoil the atmosphere of the camp. You can stay at the campsite for about 630 yen each for a tent and tarp, and it's a well-maintained campsite with good value for money. It seems that there are regular holidays, but even if it is a holiday, you can use it as long as you pay the bill the next day. It's good that there are no fixed check-in and check-out times and you can relax, but I wonder if the same is true during holidays. If so, there is a possibility that there are still campers from the previous day and you may not be able to enter. Also, you can't make reservations, so if it's full, you'll have to give up. In fact, although it wasn't packed this time, it was almost full. When you're crammed into a camp, it's hard to tell whether you're here to enjoy nature or to see people. Considering the recent camping boom, I think it's better to make reservations before holidays. Also, in my personal opinion, the most convenient time for check-in and check-out is around 12:00 or 13:00.
