The setting is a “rental room” inn in Beppu, a hot spring resort. Accommodation is inexpensive. There is no formal service. But its mysterious charm attracts people. The inn began by renting out rooms to hot-spring cure guests, but now it attracts a wide variety of visitors, including a person who has been staying in a room for three years, two women who came for a trip before giving birth, and a man who continues to travel alone. There was also a couple who came for a hot-spring cure for an illness. For three days, we listened to the voices of visitors and wondered what they were thinking when they stayed in the rental rooms.
