Satomi Yoshiyori

Japanese: 里見義頼 - さとみ・よしより

Year of death: Tensho 15.10.26 (1587.11.26)
Year of birth: Year of birth unknown. Warlord of the Warring States period. Eldest son (or younger brother) of Yoshihiro. Commonly known as Taro, his original name was Yoshitsugu. From an early age, he was in the Satomi domain and had jurisdiction over the Awa region (Chiba Prefecture), but when Yoshihiro died on May 20, 1578 (Tensho 6), a dispute arose between Yoshihiro's son Umeomaru Satomi Umeomaru, whose mother was the daughter of the Koga kubo Ashikaga Haruuji, over his inherited domain, which developed into a civil war. In the midst of this conflict, Yoshiyori took one character from the name of Yoritsune, the surviving child of the Koyumi kubo Ashikaga Yoshiaki, and changed it to Yoshiyori. Using this authority, he subjugated Umeomaru and his sympathizers in the following year. Shortly after, a rebellion by Masaki Noritoki broke out, but this was also subjugated in October of the following year, achieving unified control of the Satomi domain in both name and reality. Later, in order to incorporate the power of the Masaki clan into the Satomi clan, he had his second son, Bettomaru, succeed the Masaki family name, and worked to improve domestic affairs by expanding control of the territory through the Ryushuinjo. On the other hand, he demonstrated his skillful diplomatic skills by conducting all-round diplomacy with the Odawara Hojo, Kai Takeda, Hitachi Satake, and Echigo Uesugi clans, and even negotiating with the Toyotomi government early on.

生年：生年不詳
戦国時代の武将。義弘の長子(弟とも)。通称太郎,初名を義継と称す。早くから里見領国にあって安房地方(千葉県)を管轄していたが,天正6(1578)年5月20日義弘が没するや,義弘の子で母は古河公方足利晴氏の娘である梅王丸里見梅王丸との間に遺領を巡る抗争が起き,内乱に発展した。この争乱の最中,小弓公方足利義明の遺児頼淳の諱の1字をもらい義頼と改名し,その権威を背景に同8年には梅王丸およびその同調者を制圧。その直後,今度は正木憲時の反乱が勃発するが,これも翌年10月に制圧し,名実ともに里見領国の一元化支配をなしとげる。その後正木氏の実力を里見家中に取り込むため,次男の別当丸をして正木家の名跡を継がせ,また竜朱印状による領国支配を進展させるなど内政の充実に努めた。一方,小田原北条・甲斐武田・常陸佐竹・越後上杉氏などと全方位外交を繰り広げ,さらに豊臣政権ともいち早く交渉をもつなど,巧みな外交手腕を発揮した。
