Tsugaru District, Mutsu
was a district located in the old province of Mutsu, Japan (now in current Aomori Prefecture). The district once had a land in southern Hokkaido but in 1878, the district dissolved by splitting up into 5 districts. As the Tsugaru Domain, the area was considered a de facto province in its own right, and even today Japan Rail and other local railroad stations prefix Tsugaru- to their names instead of Mutsu- as in stations in the rest of Aomori Prefecture.
