駿府城
Tokugawa Ieyasu continued his campaigns allied with Toyotomi Hideyoshi. After their victory at the siege of Odawara Castle in 1590, Ieyasu agreed to relinquish all of his domains to Hideyoshi in exchange for the Kantō region to the east. Hideyoshi died in 1598. By 1603, Ieyasu had recovered Sunpu Castle and completed his unification of Japan, and had been named "shōgun" by the Emperor. The following year, he had Ryūsen-ji moved from Yunoki to Kōyamachi near Sunpu Castle and attended Buddhist funeral rites conducted in honor of the late Lady Saigō on the anniversary of her death. To mark the occasion, Ieyasu presented the temple priests with the "katana" he inherited from his father, and a portrait of himself as he looked at the time. These items can still be viewed at the temple in Shizuoka city.
