Daijo Tomomoto

Daijo Tomomoto was the eldest son of Daijo Sukemoto, founder of the Daijo house of Hitachi Province, and succeeded him as Hitachi Daijo. When Sukemoto died, Oda Tomoshige challenged Tomomoto's right to the post.

In 1227 the Kamakura regent Hojo Yasutoki ruled in his favour, citing Minamoto no Yoritomo's written order that the office pass from Sukemoto to his heir. The judgement confirmed the family's hereditary hold on the post, and Tomomoto was succeeded by his son Suemoto.
