The Ōoku (大奥 great interior) refers to the harem of Edo Castle, the section where the women connected to the reigning Shogun resided. Similar areas in the castles of powerful Daimyo, such as the Satsuma Domain, were also referred to by this term.
The Ōoku was built inside the Honmaru enceinte of Edo Castle in 1607 by Tokugawa Hidetada,^ who passed a special law for the Ōoku which was completely separated from the outside world. Therefore, noblewomen living in the Ōoku could not leave the castle without permission, and that no women within the Ōoku can have a relationship with man. This system lasted for nearly 200 years.
There were no male adults admitted onto the floor of the Ōoku without the Shōgun. The corridor through which the Shōgun entered was called Osuzu Rōka (御鈴廊下, large corridor of the bells), derived from the ringing of the suzu bells to announce the entrance of the Shōgun. This corridor was the only route which connected the Ōoku to rest of Edo Castle, and it was usually locked.
There is Honmaru (本丸) where Midaidokoro, shogun's official wife and her children resided (though only Oeyo, wife of Tokugawa Hidetada resided with her children) but the heir must live in there until his coming age and move to Sannomaru. Ninomaru (二の丸) was shogun's concubines with their children resided and Sannomaru (三の丸) was Oomidaidokoro (the past shogun's official widow) and the past shogun's widow concubine who didn't have child also mother of the shogun resided in there. Nagatsubone was senior chamberlain and servants resided, also the heir must live here after coming age until he appointed as shogun. Also there is Nakanomaru (中之丸) where the Noh being played but during reign of third shogun, this place was resided by his wife, Takatsukasa Takako after she had micarriages for 3 times.
With the last fire that destroyed the Honmaru Palace of Edo Castle and the end of the Shogunate with the Meiji reforms, the Ōoku also ceased to exist.
The women's quarters included the shōgun's mother, the official wife (seishitsu), and concubines. Rumored to house several thousand women, including maids and servants at one point, the Ōoku was, as much as any other part of Edo Castle, a focal point of political intrigue for the Tokugawa shogunate.
