History
Etchū-Daimon Station opened on 15 October 1923 as a general station on the Hokuriku Main Line of the Japanese Government Railway in what was then Ōshima Village (now the city of Imizu), Toyama Prefecture. Residents of the surrounding Daimon area had petitioned for a station since the 1912 Diet session, when local town and village heads formally submitted a request that was accepted by the House of Representatives' petition committee. The station was reassigned to JR West on 1 April 1987 and transferred to the third-sector Ainokaze Toyama Railway on 14 March 2015 with the opening of the Hokuriku Shinkansen extension to Kanazawa. It also remains a Japan Freight Railway terminal for private-siding traffic.

Notes
The 'Etchū' prefix in Etchū-Daimon was added because the Sanyō Main Line already had a station simply named Daimon when the station opened in 1923.
