Young women - Onago Wakaishu

...an age group of young women that was once formed within a village. In addition to the daughter group, there are other names such as daughter friends, women's groups, women's young groups, and women's young men (onago wakaishu). Many of them were accompanied by a daughter's lodging house, and researchers sometimes refer to the girls who gather at a daughter's lodging house as a daughter group, but there were also daughter groups that did not have a specific daughter's lodging house.

*Some of the terminology that refers to "Joshi Wakashu" is listed below.
