notes=The Zenkunen War (前九年合戦, "zenkunen kassen"), also known by the English translation Early Nine-Years War, was fought from
1051 to1063 , in Japan'sMutsu province , at the far north of the main island ofHonshū . Like the other major conflicts of the Heian period, such as theGosannen War and theGenpei War , the Zenkunen war was a struggle for power within the samurai clans.While most provinces were overseen by just a Governor, Mutsu, in what is now the
Tohoku region , had a military general in charge of controlling the Ainu natives, who had been subjugated when the Japanese took over the area in the ninth century. Historically, this post was always held by a member of theAbe clan , and there were many conflicts between the Abe general and the Governor over administrative control of the province.In
1050 , the general overseeing the Ainu wasAbe no Yoritoki , who levied taxes and confiscated property on his own, rarely paying any heed to the wishes of the province's Governor. The Governor sent word to the capital inKyoto asking for help, and as a resultMinamoto no Yoriyoshi was appointed both Governor and commander-in-chief over controlling the natives. He was sent with his son Yoshiie, then age fifteen, to stop Abe.The fighting lasted for twelve years, or nine if one subtracts short periods of ceasefire and peace. Skirmishes were fierce and many, but few major battles were fought until the
battle of Kawasaki in1057 . Abe no Yoritoki had been killed shortly before, and the Minamoto were now fighting his son,Abe no Sadato , who defeated them at Kawasaki and pursued them through a blizzard.The government forces, led by the Minamoto, had much trouble for quite some time, due to the harsh terrain and weather, but were eventually reinforced with new troops, including many offered by the Governor, a member of the
Kiyohara family , of the nearbyDewa province . In1062 , Minamoto no Yoriyoshi, along with his son, led an assault on an Abe fortress on the Kuriyagawa. They diverted the water supply, stormed the earthworks and stockade, and set the fortress aflame. After two days of fighting, Sadato surrendered.Minamoto no Yoshiie is thus considered the founder of the Minamoto clan's great martial legacy, and is worshiped as a particularly special and powerful ancestor "
kami " of the clan. As a "kami" and a legend, he is often called "Hachimantarō", "Child ofHachiman , the god of war."References
