Yobai (Japanese: 夜這い; "night crawling") was a Japanese custom usually practiced by young unmarried people. It was once common all over Japan and was practiced in some rural areas until the beginning of the Meiji era and even into the 20th century.^[10]

Description

At night, young unmarried men silently entered houses with young unmarried women. A man would silently crawl into a woman's room and make his intentions known. If the woman consented, they would have sex. By the morning, he would leave.^[1][2] The girl's family might know about it but pretend they did not.^[2] It was common for young people to find a spouse like this.^[1][3]

According to ethnologist Akamatsu Keisuke, the practice varied from place to place. In some areas, any post-puberty woman, married or unmarried, could be visited by any post-puberty man, married or unmarried, from the village and even by men from other villages and travellers. In other places, only married women and widows could be visited, while single girls could not. And there were variations; for example, the "closed type" yobai was a custom in which only men from the same village had the right of visitation.^[8]
