The biggest battle took place in Isawa, between Japan and the Emishi who lived nearby; some of the names of leaders of the battle include KOREHARI no Azamaro, who is known from Hoki no Ran, in which he once took control of Taga-jo Castle in 780, and Aterui, who wiped out the expeditionary force in the Battle of Subushi in 789.
最大の戦いは胆沢とその周辺の蝦夷との戦いで、780年に多賀城を一時陥落させた宝亀の乱の伊治呰麻呂、789年に巣伏の戦いで遠征軍を壊滅させた阿弖流為（アテルイ）らの名がその指導者として伝わる。
