Tokugawa Ietsuna
Tsuguhito-shinnō was granted the title of Crown Prince; and the following year, he became Emperor when Empress Meishō abdicated. His sister stepped down from the throne and the succession ("senso") was received by the new monarch. Shortly thereafter, Emperor Go-Kōmyō is considered to have acceded to the throne ("sokui"). The events during his lifetime shed light on his reign. The years of Go-Kōmyō's reign correspond with a period in which Tokugawa Iemitsu and Tokugawa Ietsuna were leaders at the pinnacle of the Tokugawa shogunate.
