The most convenient is that there is a supermarket Izumiya opposite first Cabin Nijo. Although the air-cond was quite cold, you can get an extra blanket by the floor entrance. Free ice-block and drinks at the lobby. The worse thing is for guys you have to walk through the lobby to get into the hot springs bath house. Also wifi didn't work inside the capsule.
