Yoshimasa Kiso

Japanese: 木曾義昌 - きそ・よしまさ

Year of death: Bunroku 4.3.17 (1595.4.26)
Year of birth: Tenbun 9 (1540)
A military commander in the Azuchi-Momoyama period. Son of Yoshiyasu, lord of Kiso in Shinano Province (Nagano Prefecture). Iyo no Kami and Saemon no Kami. In 1555, he submitted to Takeda Shingen in Kai (Yamanashi Prefecture) and took Shingen's daughter as his wife. Under the Takeda clan, he expanded his domain and took control of the entire Kiso district. When Takeda's decline began to show, he quickly confided in Oda Nobunaga. In February 1582, Takeda Katsuyori's army learned of this and attacked Kiso, but with reinforcements from Oda Nobutada, he defeated them at Torii Pass. In March of the same year, Nobunaga granted him additional control of Azumi and Chikuma districts, but he was unable to actually control them as Nobunaga died in June, and he ended up fighting with Ogasawara Sadayoshi over ownership of the two districts. After the Siege of Odawara in the same year, he was transferred to the Kanto region by Tokugawa Ieyasu, and was given 10,000 koku of land in Kaijo County, Shimousa, and established his residence in Amido (Asahi City, Chiba Prefecture). He is considered a traitor in Yamanashi Prefecture and a brave lord in Kiso, but he is a typical example of a small lord who survived the Sengoku period. There is also a theory that he died on the 13th. <References> "Kiso Kokin Enkakushi" "Kiso Fukushimachoshi"

安土桃山時代の武将。信濃国(長野県)木曾の領主義康の子。伊予守,左馬頭。弘治1(1555)年に甲斐(山梨県)の武田信玄に下り,その娘を妻とした。武田氏のもとで支配域を拡大し,木曾郡全域を領した。武田氏に衰えがみえ始めると,いち早く織田信長に内通する。天正10(1582)年2月これを知った武田勝頼の軍が木曾に攻めてくると,織田信忠の援軍を得て鳥居峠で破った。同年3月信長から安曇・筑摩両郡を加増されたが,6月に信長が死んだため実際の支配はできず,2郡の領有を小笠原貞慶と争うことになる。同18年の小田原攻めののちは徳川家康の関東移封に従い,下総の海上郡に1万石を領して網戸(千葉県旭市)に居館を構えた。山梨県では裏切り者とされ,木曾では勇敢な領主とされるが,小領主として戦国時代を泳ぎ渡った典型的な人物である。なお,没した日を13日とする説もある。<参考文献>『岐蘇古今沿革志』『木曾福島町史』
