Onodera Michitsuna - Onodera Michitsuna

...A group of warriors in the Middle Ages. The founder was Onodera Zenji Yoshihiro, the son of Fujiwara no Hidesato-ryuu Yamauchi Sudo Yoshimichi, who made Onodera Yasu in Shimotsuke Province his family home in the late Heian period. During the time of his son Michitsuna, he served under Minamoto no Yoritomo and became a retainer of the Kanto region, expanding his territory. Michitsuna, Michiharu, Yasumichi, Michikage, and Chikamichi were the heads of the family, and the family branched out into the following branches: Michitsuna's son Hidemichi, Michiharu's son Michihide and Michiuji. The Onodera family of Michifusa lineage, whose family home was in Nitta and Toyone counties in Mutsu Province, is also considered to be a family branch that branched out in the early Kamakura period. After the Nanboku-cho period, it was the Michiuji line that grew into local lords in Shimotsuke Province based in Onodera Yasu, but it was the family based in Ogatsu County in Dewa Province that was appointed as a Kyoto fuchishu by the Muromachi Shogunate, given land in Kyoto, and became a powerful feudal lord.
