Sasaki Yoshikiyo

was a samurai member of the Minamoto clan, who was the founder of Izumo-Genji clan.

Background

Sasaki Yoshikiyo was born the fifth son of Sasaki Hideyoshi, who was the head of the Sasaki clan of Uda-Genji (Uda-Gen clan), based in Sasaki-no-sho, Gamo-gun Manor in Ōmi Province. His father Hideyoshi Sasaki fought against the Taira clan in the Hōgen (1156) and Heiji Wars (1160). Following his defeat in 1160, Hideyoshi was deprived of his feudal estate, and moved away to Sagami Province. Shibuya Shigekuni respected Hideyoshi's bravery and sheltered Hideyoshi in his territory and had his daughter marry Hideyoshi.

Sasaki Yoshikiyo was born in Sagami in 1161 as the fifth son of Sasaki Hideyoshi. His mother was a daughter of Shibuya Shigekuni. Although Yoshikiyo had four elder brothers, they were by different mothers. Yoshikiyo grew up in Sagami, and married a daughter of Ōba Kagechika.

Early military career When Minamoto no Yoritomo (head of the Genji clan) raised an army to overthrow the Taira clan (Heike) in 1180, Yoshikiyo's half-brothers sided with Yoritomo. Shibuya Shigekuni, who was Yoshikiyo's maternal grandfather, sided with the Taira clan, and Oba Kagechika, who was his father-in-law, became the head of the Tairas' army. Shigekuni's longtime kindness made Hideyoshi unable to make up his mind. As a result, although he sided with the Tairas officially, he sided with Yoritomo in fact. His son Yoshikiyo also worried about the same problem, but he decided to side with the Taira clan finally. Yoshikiyo, who was on the Tairas' side, won the Battle of Ishibashiyama, which turned out to be the first fight of a series of wars. On the other hand, Yoritomo, who was on the Genji side, won the Battle of Kise-gawa, which broke out next. Yoshikiyo surrendered to Yoritomo, and after that, he sided with the Minamotos and fought in the Genpei War. In 1185, the Taira were overthrown in the Battle of Dan-no-ura. After the war ended, his four elder half-brothers were praised for their distinguished military services by Yoritomo, and they got their own feudal estates. But since only Yoshikiyo had been on the enemy side at first, he was not granted any reward. However, he kept on working seriously without resentment.

In 1221, the Jōkyū War broke out. He sided with Bakufu (Kamakura Shoguneto) and won a victory in this war. His distinguished military service and his old achievements were praised by the Bakufu and he became the governor of both Oki Province and Izumo Province.

Later life When he became the governor of Oki and Izumo he emigrated to Izumo. In 1242, Yoshikiyo died at age 81. Since his posterity prospered there, future generations called him the "founder of the Izumo Genji".
