History
Komatsukawa Station opened on 25 July 1950 as Komatsukawa Temporary Boarding Point (小松川仮乗降場) in Sannai Village, Hiraka District — initially without ticket sales — and was promoted to a full station on 25 December 1951. It joined JR East on 1 April 1987. The station now sits in Yokote City, formed on 1 October 2005 by the merger of the original Yokote City with Masuda, Hiraka, Omonogawa, Ōmori and Jūmonji towns and Sannai and Daiō villages — Sannai Village, where this station lies, being one of the eight merging units. Yokote is in the centre of the Yokote Basin in southern inland Akita Prefecture; the Yokote article highlights the city's February kamakura snow-hut festival, the B-class gourmet "Yokote yakisoba", and Yokote Castle, built in 1602 by the Satake clan as a satellite of Kubota Castle and one of only two domain satellites in Akita to survive the one-castle-per-domain edict before burning in the Boshin War.

Notes
The Yokote City article notes that Komatsukawa Pass was, in the Edo period, an official road from Akita domain over the Ōu Mountains to Morioka domain — the "Komatsukawa Kaidō" — and that the modern National Route 107 is its successor. The Kitakami Line that the station sits on follows essentially that same corridor between Yokote in the Yokote Basin and Kitakami in the Kitakami Basin.
