Satomi Yoshihiro

Japanese: 里見義弘 - さとみ・よしひろ

Year of death: May 20, 1578 (June 25, 1578)
Year of birth: 1525
A military commander in the Sengoku period. He was the eldest son of Yoshitaka. He was known as Taro. Together with his father Yoshitaka, he built the heyday of the Satomi clan's feudal domain system in Boso. Externally, he initially took a pro-Uesugi stance, but intervened in the issue of succession to the Koga kubō, and came into conflict with the Hojo clan and Ashikaga Yoshiuji, who supported them. Although he was defeated in the second Battle of Kokunodai in 1564 (Eiroku 7), he used his victory in the Battle of Mifuneyama in the same year to drive the Hojo forces out of Boso, and when the Echigo-Sagami Alliance was formed, he broke with the Uesugi clan and achieved political independence. In 1572 (Genki 3), as "vice shogun," he hosted the repair of Tsurugatani Hachiman Shrine. It was also around this time that he created the "Phoenix Seal," which expressed his intention to be an ideal ruler. However, when his father, Yoshitaka, died of illness in 1574, problems erupted both at home and abroad, and he died of illness without resolving the issue of his successor.

戦国時代の武将。義尭の嫡子。通称太郎。父義尭と共に房総における里見氏大名領国制の全盛期を築き上げる。対外的には,当初親上杉氏の姿勢をとり,古河公方の継承問題に介入して北条氏,およびその擁立する足利義氏と対立した。永禄7(1564)年の第2次国府台の戦では敗戦を喫したものの,同10年の三船山の戦での勝利を機に北条氏勢力を房総の地より駆逐し,越相(越後,相模)同盟が結ばれるや上杉氏と決別,政治的自立を果たした。元亀3(1572)年には「副将軍」として鶴ケ谷八幡宮修造を主催。またこのころ,理想の為政者たらんとの意志を表明する「鳳凰の印判」を創始した。しかし天正2(1574)年に父義尭が病死するや内外に問題が噴出し,後継者問題も解決しないまま病死。<参考文献>滝川恒昭『房総里見氏の印判について』
