I think it's the best if you stay with a large number of people. There are two sets of baths and toilets, so even a large number of people can stay comfortably. There was a mistake between the owner and the site side, but it was very good to be prepared immediately.
It's about a 15-minute walk to American Village. There's a paid parking lot available for 1000 JPY per night, with assigned parking spots. The non-Japanese male staff at the front desk was unfriendly. The kitchenware was in very poor condition. There's a washing machine, but you have to buy laundry detergent from the front desk; they charge 50 JPY for a single wash's worth. It's not a small packet, but rather they dispense a single-use amount from a large bottle. This is very inconvenient for travelers.
