According to the mythological records of ancient Japan, Abihiko was part of a prestigious family from Yamato and the older brother of Nagasunehiko. When the army led by Emperor Jimmu's older brother, Itsuse no Mikoto, reached Naniwa (where modern day Osaka now stands) from the east, Abihiko and his brother's forces were able to repel them and kill Itsuse no Mikoto in the fray. However, when Jimmu and his army reappeared from the west, Abihiko along with his brother's army were taken by surprise and pushed back to Yamato. While there, Jimmu met with Nigihayahi, who both claimed to be descendants of Takamagahara. Nigihayahi eventually accepted Jimmu's legitimacy, and Jimmu ascended to the throne.
After Jimmu had taken control of Yamato with the consent of Nigihayahi, Abihiko and Nagasunehiko migrated to Tsugaru, where it is said they founded a dynasty of their own.
