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。

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). - Wikipedia日英京都関連文書対訳コーパス

また平安時代の草紙などには野外で糞便する光景が描かれているように庶民には便所というものがなかった。

Books and so on from the Heian period picture scenes where people evacuate in the field; therefore, the commoners did not have lavatories. - Wikipedia日英京都関連文書対訳コーパス

社会基盤がもっと整備されると、市街の神社や寺や門などから、伝統的な日本家屋の道と敷地の間の垣根や、屋外にあった便所や納戸や蔵、住居と外部を仕切る雨戸や障子なども、常世と現世の端境と考えられた。

Once social infrastructures were further improved, many things were considered as boundaries between tokoyo and utsushiyo, from shrines, temples and gates of cities to hedges that separate the streets from the premises of traditional Japanese houses, bathrooms, storage rooms and storage shelters located outside the house, and even amado (wooden shutters constructed at the various openings of a building) and shoji (paper-covered sliding screens) that separate the house from the outside. - Wikipedia日英京都関連文書対訳コーパス
