Sleeping and Sitting on the Floor in Japan
A lot of Japanese sleep on the subways and trains. At home they often sleep on futons (but many also sleep on beds). In the summer they sleep under towels. After waking up a futon sleeper is expected to fold up his or her futon and blankets and place them in a closet or against a wall.
The Japanese spend a lot of time sitting on the floor, and if given the choice some would rather sit or lie down on a hard floor than relax on a bed or in a comfortable chair. When sitting on the floor many people sit on cushions.
