The area of Tsugaru was part of the holdings of the
Tsugaru clan of
Hirosaki Domain in the
Edo period. After the
Meiji restoration, the area was organised into
Nishitsugaru District, Aomori. With the post-
Meiji restoration establishment of the modern municipalities system on April 1, 1889, the area became part of
Nishitsugaru District, Aomori on April 1, 1889. The village of Kizukuri was raised to town status on May 1, 1901. Kizukuri expanded by merging with the neighboring villages of Koshimizu, Shibata, Kawayoke, Shussei, Tateoka and part of Narusawa on March 30, 1955. The city of Tsugaru was established on February 11, 2005, from the merger of the town of
Kizukuri, and the villages of
Inagaki,
Kashiwa,
Morita and
Shariki (all from Nishitsugaru District). ==Government==
