Fujiwara no Sumitomo

Fujiwara no Sumitomo (died 941) was a Heian-period noble of the northern Fujiwara house, a son of the Dazaifu official Fujiwara no Yoshinori. Posted as an assistant governor of Iyo Province to suppress the pirates of the Seto Inland Sea, he became their leader instead.

In 939 he rose in Iyo in concert with Taira no Masakado's eastern revolt and captured Dazaifu in 941. Defeated at Hakata Bay by Ono no Yoshifuru, he was captured in Iyo and executed by Tachibana no Tōyasu.
