In the Edo period, Edo bakufu (Japanese feudal government headed by a shogun) laid down the regulations on costumes of the women in O-oku (the inner halls of Edo-jo Castle where the wife of the Shogun and her servants reside), and the other Daimyo families (feudal lord families) came to follow this convention, too.
江戸時代になると江戸幕府により大奥の女性の服装に規定が定められ、他大名家においてもこの慣例に倣うようになった。
