Korea invaded Tsushima Province. 1423 (Ōei 30, 2nd month): Shōgun Yoshimochi retired in favor of his son, Ashikaga Yoshikatsu, who was 17 years old. March 17, 1425 (Ōei 32, on the 27th day of the 2nd month): Shōgun Yoshikatsu died at the age of 19 years, having administered the empire for only three years. February 3, 1428 (Shōchō 1, 18th day of the 1st month): Shōgun Ashikaga Yoshimochi, having taken power again after the death of his son, died himself at the age of 43. August 30, 1428 (Shōchō 1, 20th day of the 7th month): Emperor Shōkō died at the age of 27.Nihon Ōdai Ichiran suggests a cause of death by explaining: "Ce prince, s'occupait de magie et du culte de démons, mens une vie pure, et observa rigoureusement l'abstinence et le jeùne." ("This prince, who occupied himself with magic and the cult of demons, led a pure life, and rigorously observed abstinence and fasting.") Shōkō had no heirs of his own; and for this reason, Emperor Go-Komatsu selected Shōkō's third cousin for Shōkō to adopt as heir. This cousin would accede to the Chrysanthemum Throne at age 10 as Emperor Go-Hanazono on September 7, 1428 (Shōchō 1, 29th day of the 7th month): Emperor Go-Hanazono accedes to the throne at age 10. He is enshrined with other emperors at the imperial tomb at Fukakusa no kita no Misasagi (深草北陵) in Fushimi-ku, Kyoto. Kugyō Kugyō (公卿) is a collective term for the very few most powerful men attached to the court of the Emperor of Japan in pre-Meiji eras. Even during those years in which the court's actual influence outside the palace walls was minimal, the hierarchic organization persisted. In general, this elite group included only three to four men at a time. These were hereditary courtiers whose experience and background would have brought them to the pinnacle of a life's career. During Shōkō's reign, this apex of the Daijō-kan included: Sadaijin Udaijin Nadaijin DainagonEras of Shōkō's reign The years of Shōkō's reign are more specifically identified by more than one era name or nengō.
