geisha house manager (Edo period)
Archaic term for a woman who managed geisha in the Edo period. Not used in modern Japanese.
In the pleasure quarters of the Edo period, the 'musumebun' took care of the geisha.
Compound of 娘 (musume, 'daughter') and 分 (bun, 'part' or 'role'), literally 'daughter role'. The archaic geisha-related sense likely developed from the idea of a woman acting in a maternal or managerial role over younger geisha.
