History
Izumi-Tamagawa Station opened on 1 April 1927 as a stop on the Odakyu Odawara Line, located in Komae, Tokyo, 14.4 kilometres from Shinjuku. Originally named after the Tama River it borders, the station was paired with neighbouring Inada-Tamagawa (today's Noborito) on the opposite bank. The line was elevated in March 1995 and a permanent four-track elevated platform layout was completed in 1997 as part of the Odakyu quadruple-tracking project. Station numbering OH 17 was introduced in January 2014, and through-running to the Tokyo Metro Chiyoda Line began here in March 2018, with semi-express service added in March 2025.
