History
Higashi-Mukōjima Station first opened on 1 April 1902 as Shirahige Station on the Tobu Isesaki Line when the Azumabashi-to-Kita-Senju section launched. Service was suspended on 15 July 1905 and the stop was formally closed on 4 April 1908, only to reopen as Tamanoi Station on 1 October 1924 amid the urban rebuild following the 1923 Great Kantō Earthquake. The station burned in the 10 March 1945 Tokyo air-raid and lay dormant until reopening on 1 October 1949. Elevation work was completed on 21 February 1967, and on 21 December 1987 it adopted its current name. The Tobu Museum opened beneath the elevated platforms on 20 May 1989, and station number TS 05 was assigned on 17 March 2012.

Notes
Even after the 1987 rename, station signage still notes the former Tamanoi name — the area immediately east of the station was the famed Tamanoi pleasure quarter that inspired Kafū Nagai's 1937 novel A Strange Tale from East of the River.
