Events of Go-Yōzei's life

Prince Katahito became emperor when his grandfather abdicated. The succession (senso) was considered to have been received by the new monarch; and shortly thereafter, Emperor Go-Yōzei is said to have acceded (sokui). The events during his lifetime shed some light on his reign. The years of Go-Yōzei's reign correspond with the start of the Tokugawa shogunate under the leadership of Tokugawa Ieyasu and Tokugawa Hidetada.

On 31 December 1571, the Imperial prince who became known by the posthumous name of Go-Yōzei-tennō was born. On 5 November 1586, Prince Katahito was given the title Crown Prince and heir Go-Yōzei abdicated on 9 May 1611 and his son Prince Masahito received the succession (the senso). Shortly thereafter, Go-Mizunoo formally ascended to the throne (the sokui).
