Sunpu Castle
Once she was in a respected and secure position as first consort and mother to Ieyasu's heir, Lady Saigō used her influence and wealth for charitable purposes. A devout Buddhist, she donated money to temples in Suruga Province, where she resided as the consort of Ieyasu, first in Hamamatsu Castle and later in Sunpu Castle. As she was quite near-sighted, she also established a charitable organization that assisted visually impaired women with no other means of support. Lady Saigō died at a fairly young age, under somewhat mysterious circumstances. Although murder was suspected, no culprit was identified.
