[Machine Translation] How were these historical heroes narrated, created, and established in the memories and historical perceptions of the Japanese people? The awe of the vengeful spirits of Taira no Masakado, Sugawara no Michizane, and others. Tamuramaro Sakagami and Yorimitsu Minamoto, who were entrusted with the tale of their military history. The legends of Chinzai Hachiro Tamecho and Minamoto no Yoshitsune, whose legends expanded from the western provinces to the Ryukyus and from Mutsu to the continent. From Noh and Joruri to modern national textbooks, we attempt to rediscover medieval history in the legends.
