Heyako Aritsuna

Heyako no Aritsuna (?–1186), also called Ashikaga no Aritsuna, was a warrior of the Fujiwara-line Ashikaga clan of Shimotsuke Province, descended from Fujiwara no Hidesato and ancestor of the Sano and Asonuma families. As steward of the Tōdai-ji estate of Heyako-ho he built Fuma Castle. In 1180 he joined the Taira attack on Minamoto no Yorimasa at Uji, but at the Battle of Nogimiya he sided with the Minamoto alongside his sons.

In June 1186 he fought Ashikaga Yoshikane at Akamiyama. He was shot in the left eye and killed himself while fleeing.
