Akiuji Hosokawa

A military commander during the Northern and Southern Court period. The eldest son of Yorisada. Year of birth unknown. Commonly known as Koshiro. Hyobu no Sho (Minister of Military Affairs) and Mutsu no Kami (Lord of Mutsu). Junior Fourth Rank, Lower. After the Genkō Rebellion, he followed Ashikaga Takauji and Tadayoshi, and in 1334 (Kenmu 1), he took Prince Moriyoshi Shinno to Kamakura, and during the Nakasendai Rebellion, he accompanied Tadayoshi as he and Prince Narinaga escaped from Kamakura. In 1336, he and his family traveled to Shikoku, and together with Kazuuji, the direct descendant of the Hosokawa clan, he played a central role in encouraging the Ashikaga forces to join forces with Takauji, and fought in various parts of the Kinai region. In 1338 (Ryakuo 1), together with Takano Moronao and others, he defeated Kitabatake Akiie in Izumi Province. Due to these achievements, he was appointed as the head of the Samurai Department, and was also the shugo of Kawachi, Izumi, Sanuki, and Tosa Provinces. However, in 1347 (Sadawa 3), he fought against Kusunoki Masatsura and fled to Kyoto, and the shugo of Kawachi and Izumi Provinces was given to Takano Morinaga. As a result, he played an active role on the side of Tadayoshi during the Kan'o Disturbance, and regained his position as shugo of Izumi Province when a peace agreement was reached. Later, when the conflict between Takauji and Tadayoshi flared up again, he switched sides to Takauji. In 1352 (Bunwa 1), he attacked Iwashimizu Hachimangu Shrine, the seat of Emperor Gomurakami, and finally won the battle by burning down the surrounding temples and shrines. However, he died immediately afterwards, and it was said that this was the result of the temples' punishment. His posthumous name was Shoenji Ranko. He loved waka poetry, and his works were collected in the "Fuga Wakashu" and other collections.

南北朝期の武将。頼貞(よりさだ)の嫡男。生年不詳。通称小四郎。兵部少輔(ひょうぶのしょう)・陸奥守。従四位下。元弘の乱以降足利尊氏・直義(ただよし)に従い、1334年（建武1）護良親王(もりよししんのう)を鎌倉に連行、中先代(なかせんだい)の乱では成良親王(なりよししんのう)と共に鎌倉を脱出する直義に同行したという。1336年一族で四国に渡り、細川氏嫡流の和氏(かずうじ)とともに足利方軍勢催促の中心を担い、四国勢を率いて尊氏と合流後、畿内各所を転戦。1338年（暦応1）には、高師直(こうのもろなお)らと和泉国で北畠顕家(きたばたけあきいえ)を破った。これらの功により、河内・和泉・讃岐・土佐各国の守護を兼ね、侍所頭人(さむらいどころとうにん)に任じられた。しかし1347年（貞和3）楠木正行(くすのきまさつら)と戦って京都に敗走、河内・和泉両国守護は高師泰に与えられた。このため観応の擾乱(じょうらん)では直義方として活躍、和議の成立で和泉国守護を回復した。その後尊氏と直義の対立が再燃すると、尊氏方に転じた。1352年（文和1）後村上天皇が拠る石清水八幡宮(いわしみずはちまんぐう)を攻撃、周辺の寺社を焼き払ってようやく勝利したが、直後に没したため、寺社の冥罰(みょうばつ)によるものと評された。法名勝園寺巒興(しょうえんじらんこう)。和歌を好み、『風雅和歌集』などに入集している。
