Taira no Takamochi
Taira no Takamochi (839–911), born Prince Takamochi, was a great-grandson of Emperor Kanmu. In 889, by order of Emperor Uda, he received the surname Taira and left the imperial family, becoming vice-governor of Kazusa.
Unlike absentee officials, he took up his post with his sons, built a residence in Kazusa in 898, and stayed in the east after his term. Through local marriages and new rice lands, he built up the warrior bands on which the Kanmu Taira clans were founded.
