姫路城
Norimura supported Emperor Go-Daigo and Ashikaga Takauji in the struggle to overcome the Kamakura shogunate. Akamatsu joined Takauji in capturing Kyoto from imperial forces on 23 Feb. 1336. He then became a part of the Ashikaga shogunate. Norimura constructed a fort on a hill which later became the site for Himeji Castle.
