Ryakuo

Ryakuō (暦応^?) was a Japanese era of the Northern Court during the Era of Northern and Southern Courts, lasting from August 1338 to April 1342. The emperor in Kyoto was Emperor Kōmyō (光明天皇, Kōmyō-tennō^?). Go-Kōgon's Southern Court rival in Yoshino during this time-frame was Emperor Go-Murakami (後村上天皇, Go-Murakami-tennō^?).

During the Meiji period, an Imperial decree dated March 3, 1911 established that the legitimate reigning monarchs of this period were the direct descendants of Emperor Go-Daigo through Emperor Go-Murakami, whose Southern Court (南朝, nanchō^?) had been established in exile in Yoshino, near Nara.
