Hirosaki (弘前市, Hirosaki-shi) is a city located in western Aomori Prefecture, Japan.

This came from the flag emblem of Tsugaru clan, the daimyō of Hirosaki Domain during the Edo period.

He pledged fealty to Toyotomi Hideyoshi at the Battle of Odawara in 1590, and was confirmed in his holdings with revenues of 45,000 koku.

After siding with Tokugawa Ieyasu at the Battle of Sekigahara, he was re-confirmed in his holdings with a nominal kokudaka of 47,000 koku and he began construction of a castle in Takaoka (present-day Hirosaki).

His successor, Tsugaru Nobuhira, completed the castle in 1611, but its massive 5-story tenshu was lost to lightning in 1627.

Hirosaki became the home garrison town for the Imperial Japanese Army's IJA 8th Division from October, 1898.

On March 1, 1955, Hirosaki expanded through annexation of neighboring villages of Shimizu, Wattoku, Toyoda, Horikoshi, Chitose, Fujishiro, Niina, Funazawa, Takasugi, Susono and Higashimeya.

The partnership aims to promote economic and touristic development by creating opportunities related to apples.

[9] Hirosaki has a mayor-council form of government with a directly elected mayor and a unicameral city legislature of 28 members.

The city, together with the neighbouring village of Nishimeya, contributes six members to the Aomori Prefectural Assembly.

In terms of national politics, the city is part of Aomori 3rd district of the lower house of the Diet of Japan.
