Editing Aomori Prefecture (section)

===Yayoi period to Heian period===
{{See also|Mutsu Province}}
During the Yayoi period, the area that would become Aomori Prefecture was impacted by the migration of settlers from continental Asia to a lesser extent than the rest of Japan to the south and west of the region. The region, known then as Michinoku, was inhabited by the [[Emishi]]. It is not clear if the Emishi were the descendants of the Jōmon people, a group of the [[Ainu people]], or if both the Ainu and Emishi were descended from the Jōmon people. The northernmost tribe of the Emishi that inhabited what would become Aomori Prefecture was known as the Tsugaru.<ref>{{cite journal |author=Kazuro Hanihara |title=Emishi, Ezo and Ainu: An Anthropological Perspective |journal=Japan Review |year=1990 |issue=1 |pages=35–48 |jstor=25790886}}</ref> Historic records mention a series of destructive eruptions in 917 from the volcano at [[Lake Towada]].
