Kō no Moroyasu

Kō no Moroyasu (高 師泰, died 25 March, 1351)[1] was one of the leading generals of Shōgun Ashikaga Takauji during the Nanboku-chō period, along with his brother Moronao and his cousin Morofuyu.

After a number of skirmishes, Moroyasu's army, despite being reinforced by men under Ashikaga Tadayoshi, was defeated, and withdrew into the Hakone Mountains.

Here, at Sanoyama and Mishima, another set of skirmishes took place, eventually resulting in the destruction of Nitta's Imperial force when the shōgun arrived with further reinforcements.

This enmity would be the main trigger of the Kannō Disturbance, an extremely divisive and damaging civil war between Takauji and Tadayoshi with very serious repercussions for the whole country.

Although Takauji ultimately won, he was initially defeated in March 1351 by Tadayoshi and a truce was agreed upon with the help of Zen master Musō Soseki, who was close to both sides.
