Yoshinao Otomo

The ancestor of the Bungo Otomo clan. A powerful vassal in the early Kamakura period. His childhood name was Ichiboshimaru. He was Buzen no Kami. He was a Junior Fifth Rank. The Otomo Family Documents and other sources state that he was an illegitimate son of Minamoto no Yoritomo, but it is more appropriate to say that he was the son of Kondo Yoshishige, the governor of Sagami's Furusho district. His mother was the daughter of Hatano Shiro Tsuneie, and as his elder sister married Nakahara Chikayoshi, his nephew Yoshinao was adopted by Chikayoshi and inherited the governorship position of Otomo district, which was his mother's territory. He served as a close attendant to Minamoto no Yoritomo, inherited some of the authority of the Chinzei Bugyo (magistrate of the Chinzei region) held by his foster father, Nakahara Chikayoshi, and was given the position of land steward of Ono-no-sho in Bungo Province (Oita Prefecture), and his descendants became the guardians of Bungo Province for generations. He died in Kyoto on November 27, 1341.

豊後(ぶんご)大友氏の祖。鎌倉前期の有力御家人。幼名は一法師丸。豊前守(ぶぜんのかみ)。従(じゅ)五位下。出自については「大友家文書録」などで源頼朝(よりとも)の庶子とするが、相模(さがみ)古庄郷司(ふるしょうごうじ)近藤能成(よししげ)の子とするのが妥当である。母は波多野四郎経家(はたのしろうつねいえ)の娘で、姉が中原親能(ちかよし)に嫁した関係で、甥(おい)の能直は親能の養子となり、母方の所領である大友郷の郷司職(しき)を相続した。源頼朝の近習として仕え、養父中原親能が有していた鎮西奉行(ちんぜいぶぎょう)の権限の一部を継承し、豊後(ぶんご)国（大分県）大野荘(おおののしょう)の地頭職などを得て、子孫は代々豊後国守護職となった。貞応(じょうおう)2年11月27日京都にて死去。
