History
Inagekaigan Station opened on 3 March 1986 as a Keiyō Line station in what is now Mihama Ward, Chiba, alongside the line's initial Tokyo-to-Chiba-Minato segment. With the 1 April 1987 privatisation of Japanese National Railways, the station passed into the JR East network. The station consists of two elevated side platforms with the station building underneath. Station numbering was introduced to the Keiyō Line in 2016, with Inagekaigan assigned JE15; when Makuharitoyosuna opened in 2023, every station east of it shifted down by one number and Inagekaigan became JE16. The station is staffed and lies 35.3 kilometres from Tokyo Station, the line's western terminus.

Notes
The station's number was renumbered from JE15 to JE16 in 2023 when the new Makuharitoyosuna station opened between it and Kaihimmakuhari, pushing every downstream code down by one.
