Fujiwara no Hidesato was a warrior of the mid-Heian period. Based in Shimotsuke Province (today’s Tochigi Prefecture), he is known for killing Taira no Masakado, who rebelled in the Kanto region in 940.
Also known as “Tawara Toda,” he is famous for the legend in which, at the request of the dragon god of Lake Biwa, he slew the giant centipede coiled around Mount Mikami in Omi Province. The story is told in the Taiheiki and the otogizoshi tale Tawara Toda Monogatari.
