Higashi-Toyama Station is served by the Ainokaze Toyama Railway Line and is 48.2 kilometres from the starting point of the line at Kurikara.

Higashi-Toyama Station opened on 16 November 1908 as a station on the Japanese Government Railways (JGR), later becoming the Japanese National Railways (JNR).

It was privatized on 1 April 1987, coming under the control of JR West.

From 14 March 2015, with the opening of the Hokuriku Shinkansen extension from Nagano to Kanazawa, local passenger operations over sections of the former Hokuriku Main Line running roughly parallel to the new shinkansen line were reassigned to different third-sector railway operating companies.

[1] From this date, Higashi-Toyama Station was transferred to the ownership of the third-sector operating company Ainokaze Toyama Railway.
