Takenori Kiyohara

Date of birth and death unknown. A military commander in the late Heian period. The younger brother of Kiyohara Mitsuyori, the head of the prisoners of war in the northern part of Dewa-Yama-Poku. Some "Kiyohara family genealogy" links him to Emperor Tenmu and Prince Toneri as the son of Hyobu Daibu Mitsukata, but the Kiyohara family, head of the prisoners of war, is recognized as originally a local ruling family in the northern part of Yama-Poku (Yokote Basin, Akita Prefecture). During the Battle of Zenkunen, he came to the aid of Mutsu no Kami and Chinjufu Shogun Minamoto no Yoriyoshi and his son Yoshiie, who were having trouble with the power of the Abe clan of Mutsu, and in 1062 (Kohei 5), he led a Kiyohara army of 10,000 and joined forces with 3,000 Minamoto troops at Tamuro-ga-oka, Kurihara County, Mutsu Province (Miyagi Prefecture). On August 16, he took Komatsusaku, then destroyed Koromogawa, Oasouno, Sehara, Toriumi, Kurosawajiri, Tsuruhagi, and Hiyodori, and on September 16, he surrounded Kuryagawa and Ubato, capturing them the next day and destroying the Abe clan. Due to his achievements, he was promoted to Junior Fifth Rank, Lower Grade, Chinjufu Shogun the following year and was also given the territory of the Oku-roku-gun district.

生没年不詳。平安後期の武将。出羽山北(でわせんぽく)の俘囚主(ふしゅうしゅ)清原光頼(みつより)の弟。「清原氏系図」のなかには兵部大輔(ひょうぶだいぶ)光方(みつかた)の子として天武(てんむ)天皇―舎人(とねり)親王に結び付けるものもあるが、俘囚主清原氏は本来山北（秋田県横手(よこて)盆地）在地の豪族であると認められる。前九年の役で陸奥(むつ)安倍(あべ)氏の地力に手を焼いていた陸奥守(むつのかみ)・鎮守府将軍源頼義(よりよし)とその子義家(よしいえ)を助け、1062年（康平5）1万の清原軍を率いて3000の源軍と陸奥国（宮城県）栗原(くりはら)郡営岡(たむろがおか)で合流。8月16日小松柵(こまつのさく)を落としたのを手始めに、衣川(ころもがわ)、大麻生野(おおあそうの)、瀬原(せばら)、鳥海(とりうみ)、黒沢尻(くろさわじり)、鶴脛(つるはぎ)、比與鳥(ひよどり)の諸柵を破り、9月16日厨川(くりやがわ)、嫗戸(うばと)2柵を囲み、翌日攻略、安倍氏を滅ぼした。功績により翌年従(じゅ)五位下鎮守府将軍となり奥六郡も領する。
