History
Iimori Station opened on 20 July 1960 as an unstaffed passenger stop on the Ōito Line in the village of Hakuba, Nagano Prefecture, where it sits 56.7 kilometres from the line's starting point at Matsumoto. A grade-separated crossing south of the station was completed in December 1982. Ownership passed to JR East with the privatisation of Japanese National Railways on 1 April 1987. The line was suspended between Shinano-Ōmachi and Itoigawa for several weeks following the 22 November 2014 Nagano Prefecture earthquake before service resumed in stages. The station was added to the Tōkyō suburban zone on 14 March 2026.

Notes
Although the station joined the Tōkyō suburban zone in March 2026, Suica IC cards cannot be used here — only Shinano-Ōmachi and Hakuba within that segment accept them.
