If you go to Japan to stay in a hotel in summer, if there is no washing machine, does the hotel have a clothesline?

Many hotels have washing machines. If necessary, guests can put clothes in special "laundry bags" or baskets. There are paid services for cleaning by special personnel, and some can do their own laundry for free.

If you don't want to spend money, there is usually a clothesline above the bathroom tub in the room. This thing is like an electric bell, installed on both sides of the wall above the bathtub. Many people don't know what it does.

Actually, it's a clothesline Usually, the rope is hidden in the box. When in use, pull out the rope buckle and hang it in the buckle groove on the opposite wall. The rope itself has a tensioning device, which will jump tightly after being pulled out.
