(1324 – May 5, 1338) was one of the sons of Japanese Emperor Go-Daigo. He became involved in the Nanboku-chō wars between the true Imperial line and the Ashikaga clan. In 1336, Tsunenaga was sent along with his brother Takanaga to be escorted by Nitta Yoshiaki to Echizen Province where, it was hoped, they could escape the attacks of the Ashikaga. According to the epic Taiheiki, Tsunenaga was secretly made heir-apparent before he left, but no other documents confirm this. In fact, in November of that year, his brother Narinaga was officially named Crown Prince.
