The Battle of Kizaki (木崎原の戦い) occurred on the 4th day of the fifth month of Genki 3 (June 14, 1572) when the forces of Shimazu Yoshihiro defeated the larger army of Itō Yoshisuke.

Following their capture of Obi castle, the Itō strengthened their position on southern Hyūga and began encroaching on territory belonging to the Shimazu clan.

Still the Shimazu were able to control Ōsumi and in 1572 offered battle to Yoshisuke in the plain of Kizaki, at the border between the two provinces.

Outnumbered 10:1, the Shimazu stood in a defensive position and were able to gain victory using their famous feigned retreat.

[4] The battle, also known as "The Okehazama of Kyushu", due to how devastating Yoshihiro's victory was, seriously damaged the forces of the Ito clan and the Shimazu were left in a position to expand north, into southern Hyūga.
