Hakawa Kiyomune served as a bushō during the Sengoku and Azuchi-Momoyama periods. He was a retainer of the Chōsokabe, a sengoku daimyō family of Tosa Province.
The Hakawa were descendants of the Soga clan. Kiyomune served as the lord of Hakawa Castle in the Takaoka District of Tosa. He served as a close associate of Chōsokabe Kunichika (a daimyō and lineal heir of Chōsokabe Kanetsugu). Owing to his contributions to the defeat of Ichijō Kanesada, Kiyomune received as his formal wife the daughter of Kunichika and became a member of the Chōsokabe clan. Thereafter, Kiyomune supported efforts by Kunichika’s son, Chōsokabe Motochika, to unify Shikoku under the clan and served as the lord of Maji Castle in the Hata District of Tosa.
Later, Kiyomune was dispatched to assist Ōno Naoyuki who had defected to the Chōsokabe from the Kōno clan of Iyo Province. At this time, he made errors including reconciling on his own with Kobayakawa Takakage (who was visiting the reinforcements to the Kōno clan) forsaking Naoyuki and withdrawing. As a result, he was forced into confinement.
In 1580, a plot for a rebellion borne of his frustrations was uncovered, after which he underwent the rites of tonsure and fled to the Kaifu District of Awa Province. Upon orders of Motochika, Kōsokabe Chikayasu compelled Kiyomune to take his own life while the remnants of his family who continued to resist were all killed in battle.
Kiyomune’s lineal heir, Yajirō, fought valiantly before taking his life and his second son, Toraō (a youth of ten years old) drowned while attempting to flee. His third son, Chimi (the son of his formal wife), fled with his mother but died early. The son of his consort, after taking refuge in Iyo, returned to Tosa and changed his name to Machida Sukezaemon. Kiyomune’s youngest son, Kiyohisa, survived and the Hakawa clan continued until the end of the Edo period.
