Ejima-Ikushima affair

The Ejima-Ikushima affair (江島生島事件, Ejima Ikushima jiken) was the most significant scandal in the Ōoku, the Tokugawa shōgun's harem during the Edo period of the history of Japan, that occurred in February 1714. After inviting a Kabuki actor and others to a tea house, Lady Ejima missed her curfew into the Ōoku and became the focus of a power struggle between the mother of the ruling shogun and the wife of the late shogun. An investigation into the curfew saw 1,300 people being punished and led to the death of Ejima's brother.
