Site of Ōoku

The Ōoku (大奥, "great interior") was historically the women's quarters of Edo Castle, the section where the women connected to the reigning shōgun resided. Similar areas in the castles of powerful daimyō, such as the Satsuma Domain, were also referred to by this term. During the reign of the second shogun, Tokugawa Hidetada, Ōoku was established in Edo Castle as a women's room where his official wife (御台所, Midaidokoro), Oeyo, resided.
