Asari Katsuyori served as a bushi during the Sengoku and Azuchi-Momoyama periods.
The Hinai-Asari clan were kokujin, or provincial landowners, in the Hinai District of Dewa Province. The Hinai-Asari were an illegitimate branch of the Asari clan based in the Asari township of the Yatsushiro District of Kai Province which, in turn, were an illegitimate branch of the Kai-Genji.
Katsuyori was born as the son of Asari Noriyori. Owing to conflict with his older brother, Asari Norisuke, in 1562, he colluded with the arch-rival Hiyama-Andō clan and betrayed him, compelling his older brother to kill himself. Katsuyori then succeeded his older brother to become the next head of the clan. In addition to ancillary castles, he constructed Ōdate Castle and, to protect from the north, positioned the Tokko group below the castle and subdivided the town.
In 1582, Katsuyori was slayed at a banquet to which he was invited by the Hiyama-Andō clan and the Hinai-Asari clan disintegrated.
