Asonuma Hirotsuna

Asonuma Hirotsuna, also called Shirō, was a Shimotsuke warrior of the Fujiwara-descended Ashikaga clan, the fourth son of Ashikaga Aritsuna. He took the name Asonuma from his holding of Asonuma in Aso District.

When the head Ashikaga house joined the Taira in the Genpei War, Hirotsuna instead served Minamoto no Yoritomo and became a Kamakura gokenin. In 1189 he campaigned in Ōshū and was appointed jitō of Tōno manor in Hei District, Mutsu.
