Timetable data as of 2 May 2026.

The timetable data is incomplete for some or all lines at this station, so the weekday and Sat & holiday figures are departures in the available timetable data, not totals.

Lines where the timetable data is incomplete:

• JR Obama Line: one direction only

• JR Obama Line: Obama ⇄ Kato

Seihama Station was opened on 15 July 1961 as an unstaffed passenger-only halt added between Kato and Obama on the Japanese National Railways' Obama Line. With the privatisation of JNR on 1 April 1987 the station came under the control of JR West.

The station has no station building at all; only a small shelter sits on the single side platform, and passengers reach the platform directly from the Obama-side entrance. There is no ticket machine on site.
