Tokyo Daijingu, Shinto shrine in Fujimi, Chiyoda, Tokyo, Japan

Tokyo Daijingu is a Shinto shrine in Fujimi, Chiyoda, Tokyo, dedicated to Amaterasu-Sume-Ohkami and Toyouke-Ohkami, with four other deities in the side hall. A broad stone stairway leads through an unpainted wooden torii to a hall with a green copper roof and dark wooden facade hung with purple banners and white zigzag paper streamers. A stone stele beside the stairs reads 東京大神宮.

The shrine began in 1880 as the Kōtai Jingū Remembrance Hall on the former Ōkuma Shigenobu residence site in Yūrakuchō, built under the Meiji government's policy of unifying Shinto and state. After the 1923 Great Kantō earthquake burned the buildings, it was rebuilt and moved to its present Fujimi location in 1928, then called Iidabashi Daijingū. In 1946 it was reorganized as the religious corporation Tokyo Daijingu.

The shrine introduced public Shinto wedding ceremonies in Japan following an imperial wedding at the Imperial Palace in 1901.

The shrine sits a short walk from Iidabashi Station, accessible via multiple subway and rail lines, and opens daily between 6 a.m. and 9 p.m. Visitors can explore the grounds freely, offer prayers, and participate in traditional rituals such as ringing the bell and bowing before the main hall.

The shrine's grounds include the Iitomi Inari Shrine, a small subordinate shrine dating from its Hibiya era. It is known for the devotion of Ichikawa Danjūrō IX, the Meiji-era kabuki actor who worshipped there.
