Chiba Tanemune
Chiba Tanemune (1268–1312) was the tenth head of the Chiba clan of Shimōsa and a gokenin of the Kamakura shogunate, the second son of the eighth head Yoritane. After Yoritane died in 1275, his elder brother Munetane was posted to Hizen in Kyushu on coastal guard duty, leaving Tanemune to administer Chiba-no-shō.
When Munetane died in 1294, his heir Tanesada was young and far away in Kyushu, so Tanemune made himself the tenth Chiba head. He died in 1312 and was succeeded by his son Sadatane.
