• Aoimori Railway Line: Chibiki ⇄ Kamikitacho

Ottomo Station opened on January 4, 1894, as a stop on the Nippon Railway in what is now Tōhoku town, Aomori Prefecture. With the nationalisation of the Nippon Railway in 1906, the station was absorbed into the Tōhoku Main Line of the Japanese Government Railways. Regular freight service ended in March 1972, and with the privatisation of Japan National Railways in April 1987 it passed to JR East. On December 4, 2010, when the Tōhoku Shinkansen opened over its full length to Shin-Aomori, this section of the Tōhoku Main Line was transferred to the third-sector Aoimori Railway Company, which now operates the station.

A 28.4-kilometre forest railway once ran from Ottomo Station to the Kamikita Mine, supporting both mining traffic and local timber from the Tsubokawa basin until its closure in 1963.
