In rural areas, the configuration where the lavatory was built independently from the main housing which was a living space continued until the postwar era (as the main housing did not have a lavatory inside, they could not go to the lavatory without going out).
農村部では、居住空間である母屋とは別に、独立して便所が建てられる（母屋には便所はないので、一度外へ出ないと便所に行けない）形態が戦後まで行われていた。
