Each building has its own separate BBQ area. It's a simple structure, just a set of blocks, but if you bring your own net and charcoal, there's no rental fee for the equipment, so it's quite affordable. Of course, you can also purchase it at the administration building, so there is no problem if you forget. Another good thing is that it has a roof, so it can withstand the sudden rain that is a specialty of the northern Kanto region.
The building is quite old, but it's fine enough. Very spacious. Cooking utensils etc. are available without any inconvenience. (←The sharpness of the knife is quite poor)
The bath is a hot spring type, but it is diluted with hot water. The smell of sulfur is quite strong.
There is also a large public bath next to the administration building, so we recommend taking a quick soak in the large public bath before BBQ, and then taking a bath in the building before going to bed.
