橘樹神社, Shinto shrine in Japan

Tachibana Shrine is a Shinto shrine in Takatsu-ku with a wooden main hall reconstructed in 1851 that shows traditional architectural details. The grounds also contain the Fujimidai Kofun, a burial mound roughly 1400 years old now preserved as a park, which offers views of the Tama lowlands from certain vantage points.

The shrine was long the tutelary deity of Komogo village and was also called Tachibana-sha; it is thought to have served as the provincial shrine of Tachibana District, since the district government stood nearby. Its hall was rebuilt in 1851. The Fujimidai Kofun behind it is dated to the 6th century, and one tradition calls it the tomb of Princess Ototachibana, though no document or find confirms this.

The shrine was long called Tachibana-sha, and its name is written with the characters for the tachibana citrus. It honours Yamato Takeru and his wife Ototachibana-hime; tradition says her garments and headdress washed ashore here after she entered the sea to calm the storm. The annual festival is held on 8 October.

The shrine is reachable by bus from Musashi-Shinjo Station, taking several minutes to the Komogo stop. The walk from the bus station to the grounds is short but climbs uphill, so comfortable shoes are recommended.

Behind the shrine stands the Fujimidai Kofun, a mound about 17.5 m across and 3.7 m high, of which only the top survives after housing development cut into the hill. A rope hangs down so visitors can climb to the summit, though nearby houses now block the view. Legend calls it the tomb of Ototachibana-hime; some scholars date it to the 6th century.
