Aomori is the capital city of Aomori Prefecture, Japan. The city faces Mutsu Bay connecting Tsugaru Channel and the Hakkoda Mountains lie in the southern part of Aomori. It has the biggest seaport in the prefecture. Before Seikan Tunnel opened, Port Aomori served the city with train ferry to Hakodate in Hokkaidō, and therefore the main entrance of Honshū for passengers and cargo to and from Hokkaidō.

The city was officially founded on April 1, 1898. The town and port was however settled in 1626, in the early Edo period. Recently, the city merged with the former town of Namioka on April 1, 2005 to form the new city of Aomori.

Aomori literally means blue (or green) woods. The name is generally considered to refer to a small forest on a hill which existed near the town, used by fishermen as a landmark. A different theory suggests the name might have been derived from the Ainu language.
