The Gosannen War (後三年合戦, gosannen kassen), also known as the Later Three-Year War, was fought in the late 1080s in Japan's Mutsu Province on the island of Honshū.^[1]

History

The Gosannen War was part of a long struggle for power within the warrior clans of the time.

The Gosannen kassen arose because of a series of quarrels within the Kiyohara clan (sometimes referred to as "Kiyowara"). The long-standing disturbances were intractable. When Minamoto no Yoshiie, who became Governor of Mutsu province in 1083, tried to calm the fighting which continued between Kiyohara no Masahira, Iehira, and Narihira.^[2]

Negotiations were not successful; and so Yoshiie used his own forces to stop the fighting. He was helped by Fujiwara no Kiyohira. In the end, Iehira and Narihira were killed.^[2]

During the siege of Kanezawa, 1086–1089, Yoshiie avoided an ambush by noticing a flock of birds take flight from a forest.^[3][4]

In art

Much of the war is depicted in an e-maki narrative handscroll, the Gosannen Kassen E-maki, which was created in 1171.^[5] The artwork is owned today by the Watanabe Museum in Tottori city, Japan.
