Onarimon is a subway station on the Toei Mita Line in Tokyo, near the north side of Shiba Park and Tokyo Tower. In front of Exit A6, Shiba Park opens up and Tokyo Tower is visible for photos, while Exit A1 leads to Onarimon, the gate the station is named after. The station opened in 1973, has six entrances, and has restrooms inside the ticket gates. As of August 29, 2024, the Exit A6 elevator is stopped due to flooding, so wheelchair and stroller users should take note.
