The Kamoshika was first introduced on 1 November 1986 as an express service operating between Kami-Suwa, Iida, and Nagano. This service was discontinued from the start of the revised timetable on 13 March 1988.[3]

The Kamoshika name was revived from March 1997 as a limited express service operating between Akita and Aomori, replacing the former Tazawa limited express service which ran between Morioka and Aomori via Akita before the Akita Shinkansen was opened.[4]

From the start of the revised timetable on 4 December 2010, the Kamoshika services were discontinued, replaced by Tsugaru services, formerly operating between Hachinohe and Hirosaki, which were rerouted to operate between Aomori and Akita.[5]
