Odawara Castle
In 1590, Toyotomi Hideyoshi attacked the Hōjō stronghold at Odawara Castle in the Subjugation of Odawara, eradicating the Hōjō as a power. At that time, Ujinao appealed to his father-in-law Ieyasu, who prevailed upon Hideyoshi to spare Ujinao and Toku, sending them to Mount Kōya. In the following year, Ujinao died. Princess Tokuhime and Ujinao had two daughters: Hōshuin-dono. After Ujinao's death, the princess returned to her father, Ieyasu.
