The Tsugaru (つがる) is a limited express train service in Japan operated by East Japan Railway Company (JR East), which runs from Aomori to Hirosaki and Akita via the Tōhoku Main Line and Ōu Main Line.

[2] Services are normally formed of 4-car E751 series electric multiple units (EMUs) based at Aomori depot,[3] with Aomori-based 4-car 485-3000 series EMUs also used on some additional services during busy seasons.

[6] The Tsugaru (津軽) was first introduced on 1 October 1954 as an express service operating between Ueno in Tokyo and Aomori via Niitsu and Akita.

[7] The Tsugaru name was revived from 1 December 2002 as a limited express service operating between Hachinohe and Hirosaki, superseding the former Hatsukari limited express service which ran between Morioka and Aomori up until the opening of the Tōhoku Shinkansen extension to Hachinohe.

[1] From 4 December 2010, with the opening of the Tōhoku Shinkansen extension from Hachinohe to Shin-Aomori, the Tsugaru services were amended to operate between Aomori and Akita, replacing the Kamoshika and Inaho services that previously ran on this route.
