Hatano Harumichi served as a daimyō and as lord of Yakami Castle in Tanba Province.
Harumichi received one of the characters in his name from Ashikaga Yoshiharu, the twelfth shōgun. Harumichi’s father, Hatano Tanemichi, unified Tanba Province after expelling the Hosokawa and sent his daughter to become the formal wife of Miyoshi Nagayoshi, maintaining friendly relations with the clan. In contrast to Tanemichi’s brilliance, Harumichi was regarded as feeble-minded.
In 1548, Nagayoshi separated from Tanemichi’s daughter (Harumichi’s younger sister), causing the Hatano to align with Hosokawa Harumoto and oppose the Miyoshi clan. From his base in Yakami Castle, Harumichi repelled several attempts on the castle, but gradually began to lose against repeated attacks by the Miyoshi. After further attacks by Matsunaga Hisahide and his younger brother, Matsunaga Nagayori, Harumichi finally surrendered in 1555. He died in 1560.
