Hiuchiyama (火打ち山) was one of Minamoto no Yoshinaka's fortresses in Echizen Province, Japan. In April and May 1183, a Taira force led by Taira no Koremori attacked the fortress.^[1]

It was built on rocky crags, and well-defended; the Minamoto had even built a dam to create a moat. However, a traitor within the fortress tied a message to an arrow, firing it into the Taira camp, and revealing a way to breach the dam and drain the water. The castle soon fell to the Taira, but Yoshinaka and much of his forces survived and escaped.^[2][3]
