• Sotetsu Main Line: Wadamachi

The station opened on 1 December 1926 as Hoshikawa Station on the Jinchū Railway, the predecessor of today's Sōtetsu Main Line. The original site served as the terminus until extension toward Kita-Hodogaya (now Hoshikawa) on 31 May 1927 turned it into an intermediate stop. It was renamed Kamihoshikawa on 1 April 1933. The current footbridge station building was completed on 22 November 1972. On 10 October 1991 the station became Sagami Railway's first to receive automatic fare gates — three for entry and two for exit. Platform doors entered service on 29 September 2024.

A small Shinto shrine — Shioda Inari — was relocated into the station precincts in November 1966 and now sits beside the maintenance office; the protective talismans found inside Sōtetsu train cabs are issued from this shrine.
