Honmonji is a Nichiren-shû Buddhist temple in the Ikegami neighborhood of Tokyo's Ôta-ku. It is one of the top four temples of the Nichiren sect, and is said to have been the site of Nichiren's death.
The residence of Ikegami Munenaka previously stood on the site, which is sometimes said to have been converted into a temple in 1274. Nichiren himself stayed with Munenaka at the latter's residence for some time in 1282, while attempting to recuperate from an illness, but died there in the end. Many sources assert the temple to have not been founded until after this event.
Prominent figures buried at Ikegami Honmonji include the crew of the USS Oneida, which sank in Tokyo Bay in 1870, as well as kabuki actors Ichikawa Sadanji I, Ichikawa Sadanji II, Ichikawa Raizô VIII, Kataoka Nizaemon IX, Kataoka Nizaemon XIII, and Kataoka Ichizô III, painters Kanô Tan'yû and Kanô Takanobu, the wife and daughter of Kato Kiyomasa, and a number of women of the Kishû Tokugawa clan.
