History
Kadoshima Station opened on 30 October 1932 as the temporary terminus of the Sanshin Railway, in what is now Yasuoka village, Nagano Prefecture. It was built principally to land materials for the Yasuoka Dam and to take traffic that had previously moved by boat on the Tenryū River. On 15 November 1935 the line was extended south to Onda and Kadoshima became a through station. Nationalisation as part of the Iida Line followed on 1 August 1943. Freight and parcel handling ended on 1 December 1971, and the station was de-staffed on 24 February 1984 with the rollout of CTC control on the southern Iida Line. The 1997 demolition of the station building left only a platform shelter on the single island platform.

Notes
Built to ferry construction supplies for Yasuoka Dam, Kadoshima was reached entirely by Tenryū-River boat before its 1932 opening transferred dam-traffic from water to rail.
