Hata Mochi

Hata Mochi was a warrior of the Matsura confederation in Hizen Province and the second son of Matsura Hisashi, whose genealogies traced the family to the Heian warrior Watanabe no Tsuna. In 1102 he moved to the Hata district of Matsura, took the surname Hata, and built Kishidake Castle as his stronghold.

He thereby founded the Hata clan, which became the leading family among the Upper Matsura bands and held Kishidake for some four hundred years, down to the Sengoku period.
