• Odakyu Odawara Line: Shin-Matsuda ⇄ Kayama

Kaisei Station opened on 14 March 1985 in Kaisei, Ashigarakami District, Kanagawa Prefecture, as the 68th station on the Odakyū network and its westernmost, on the Odawara Line. Kaisei was the only municipality served by Odakyū that still lacked a station until then, and the name was taken from the host town. A preserved Odakyū 3100-series NSE car has stood in the adjacent Kaisei Ekimae Second Park since 2001. Station numbering (OH 42) was introduced in January 2014. Platforms were extended 85 m towards Shinjuku in 2018, allowing all ten-car expresses to stop from the 16 March 2019 timetable. From the 15 March 2025 timetable, all rapid expresses also stop, leaving only the limited-express Romancecar as a normal pass-through.

A retired Odakyū 3100-series "NSE" Romancecar lead car, numbered 3181, has been displayed in the park at the east exit since 2001 under the affectionate nickname "Ron-chan," with the interior opened to the public on the second and fourth Sunday of every month.
