Yoshitoshi Shibukawa

Japanese: 渋川義俊 - しぶかわ・よしとし

Year of death: November 14, 1434 (December 14, 1434)
Year of birth: 1400
A military commander in the early Muromachi period. His father was Mitsuyori, who was a Sakon no Shogen. In 1419, he was appointed as Kyushu Tandai. That year, an incident occurred in which Korea sent troops to Tsushima (the Oei Invasion) in an effort to crack down on wako pirates, but Yoshitoshi prevented this. In May 1407, he fought Shoni Mitsusada in Hakata, was defeated, and retreated to Hizen. This defeat marked a rapid decline in the power of the Kyushu Tandai. In 1408, he fought the Shoni again, but was defeated again. He died at Sakami Castle in Chikugo Province. After Yoshitoshi's death, the Kyushu Tandai lost its leadership in trade with Korea, and the Shibukawa clan lost its true role in Kyushu, becoming a minor force that controlled eastern Hizen. <References> Kawazoe Shoji, "The Process of the Decline of the Kyushu Tandai" (Kyushu Culture Research Institute Bulletin, No. 23)

室町時代前期の武将。父は満頼。左近将監。応永26(1419)年九州探題に補任される。この年,倭寇の取り締まりを巡って,朝鮮が対馬に軍勢を進めるという事件(応永の外寇)が起こったが,義俊はこれを防いだ。30年5月に少弐満貞と博多で戦い敗れて肥前に退いた。この敗戦を契機として九州探題の権勢は急速に衰え始めた。32年再び少弐氏と刃を交えたが,またまた敗退した。筑後国酒見城で死去。義俊の死後,九州探題は朝鮮交易でも主導権を喪失し,渋川氏は九州統括の実体を失い,東肥前をわずかに支配する勢力となってしまった。<参考文献>川添昭二「九州探題の衰滅過程」(『九州文化研究所紀要』23号)
