• JR Keiyo Line: Etchujima ⇄ Shin-kiba

Shiomi Station opened on 10 March 1990 on the JR East Keiyo Line in Koto, Tokyo. It had not been included in the original plan for the Keiyo Line's Shin-Kiba to Tokyo section. Suica acceptance began on 18 November 2001, and a departure melody was introduced on 25 March 2007. From 16 March 2013 Musashino-line through services began stopping after the Musashino Rapid was downgraded. The Midori-no-Madoguchi staffed ticket window closed on 31 March 2014, and the station became contracted-operations on 20 October 2014. Roof extension work begun in October 2016 finally covered the full platform length by June 2017, the original cover having spanned only four cars. JE04 was assigned at the 2016 JR East station-numbering rollout.

In fiscal 2023 Shiomi overtook Kasai-Rinkai-koen to become the busiest of the Keiyo Line's Rapid-skipped stations by daily boardings.
