Ohatsu's close family ties to both the Toyotomi clan and the Tokugawa clan uniquely positioned her to serve as a conduit between the rivals. She acted as a liaison until 1615, when the Tokugawa eliminated the Toyotomi.
When she married her cousin Kyōgoku Takatsugu in 1587, he was a daimyo in Õmi Province, holding Ōtsu castle for the Toyotomi. At this point, Takatsugu was a fudai (hereditary vassal) daimyo of the Toyotomi with a stipend of 60,000 koku annually. After 1600, Takatsugu's allegiances had been transferred to the Tokugawa; and he was rewarded with the fief of Obama in Wakasa Province and an enhanced income of 92,000 koku annually.
Her husband's changing fortunes affected Ohatsu's life as well. Surviving record books from luxury goods merchants provide insight into patterns of patronage and taste.
