[3] Lappohja is one of the original stations of the private Hyvinkää–Hanko railway; it was placed close to the location where the line meets the natural harbour of the Tvärminne Storfjärden bay of the Gulf of Finland.

[3] Lappohja was included in the area leased by Finland to the Soviet Union in the aftermath of the Winter War.

On the onset of the Continuation War and the escape of Soviet troops from Hanko, it was discovered that the original station building and the harbour siding had been destroyed.

Ticket sale services at Lappohja were ceased in 2000, and it became an unmanned station later in the same year due to the Karis–Hanko section becoming remote controlled.

[4] The station does not have a VR service point nor a ticket vending machine, though it has a 55 centimetres (22 in) high platforms for accessible entry onto low-floor trains.
