Katsumitsu Hino

A nobleman in the mid-Muromachi period. Son of Hino Shigemasa (later renamed Masamitsu). In 1434 (Eikyō 6), he succeeded his grandfather Yoshisuke after his death. In 1455 (Kōshō 1), he became Gon Dainagon (provisional chief councilor), and in the same year, his younger sister Tomiko became the wife of Shogun Ashikaga Yoshimasa, which led to him strengthening his power. In 1465 (Kanshō 6), he was promoted to Juichii (Juichii) and the following year, in 1466 (Bunshō 1), he became Regent of the In (inner monastery). He intervened in the shogunate by suppressing Shogun Yoshimasa, plotting to make Tomiko's son Yoshihisa the head of the shogun family, and together with Ise Sadachika, he expelled Yoshimi, who had already been selected as the successor, which led to the Onin War (1467-1477). In 1467 (Onin 1), he became the first man in his family to hold the position of Minister of the Interior, and was called "Oshidaijin" (Minister of the Interior), wielding exclusive power. In 1473 (Bunmei 5), when Yoshihisa became Shogun, he took charge of the shogunate as the new Shogun representative. In 1476, he became Minister of the Left, reaching the pinnacle of official rank, but died on June 15 of the same year at the age of 48. Jinson of Daijoin Temple at Kofuku-ji Temple in Nara wrote that this was "a rare divine punishment." He was called Yuishoin.

室町中期の公卿(くぎょう)。日野重政(しげまさ)（政光(まさみつ)改め）の子。1434年（永享6）祖父義資(よしすけ)の没後その家督を継ぐ。55年（康正1）権大納言(ごんだいなごん)となり、この年妹富子(とみこ)が将軍足利義政(あしかがよしまさ)の室となったのを機に権勢を強め、65年（寛正6）に従(じゅ)一位に上り、翌66年（文正1）には院の執権となる。将軍義政を抑えて幕政に介入し、富子の子義尚(よしひさ)を将軍家の家督にたてようと計り、伊勢貞親(いせさだちか)とともに、すでに後嗣(こうし)と定められていた義視(よしみ)を排斥し、応仁(おうにん)の乱（1467～77）を招くきっかけをつくった。67年（応仁1）には、同家で前例のない内大臣となり「押大臣」とよばれて専権を振るい、ことに73年（文明5）義尚が将軍になると、新将軍代として幕政を担当した。76年には左大臣となり官位を極めたが、同年6月15日、48歳で没した。奈良興福寺大乗院の尋尊(じんそん)は、これを「希有(けう)の神罰なり」と記している。唯称院と号す。
