• Sotetsu Main Line: Yamato (Kanagawa) ⇄ Mitsukyo

Seya Station opened on 12 May 1926 as a stop on the Jinchū Railway, the predecessor of today's Sōtetsu Main Line. A new overhead station building and north–south free passage entered service on 28 March 2004. Between 2010 and 2013 the station was rebuilt as two island platforms with four tracks to allow Limited Express overtaking under the Eastern Kanagawa Rail Link plan; the third track had earlier served as a passing loop in the days of freight operation. Platform doors entered service on the inner tracks (2 and 3) on 27 March 2022 and on the outer tracks (1 and 4) on 24 July 2022. Overtaking by Limited Express trains began on the up line on weekday mornings on 31 May 2015 and was extended to morning down-line services on 30 November 2019; since the timetable revision of 18 March 2023 it has run on both weekdays and weekends, mainly in the mornings and evenings.

Until 1960 an intermediate station, Futatsubashi, stood between Seya and Mitsukyō. The Ring Route 4 road that runs west of the station is known as the Kaigun-dōrō ("Navy Road"), and its avenue of cherry trees is a well-known blossom-viewing spot.
