Lady Tsukiyama was the daughter of an Imagawa retainer, Sekiguchi Chikanaga. Her mother was one of Imagawa Yoshimoto"s sisters, thus making Lady Tsukiyama Yoshimoto"s niece.
She was the mother of Ieyasu"s eldest son and heir apparent, Matsudaira Nobuyasu. In January of 1557, Lady Tsukiyama married Tokugawa Ieyasu. Tsukiyama was erratic by nature, and was completely indifferent to affairs of state.
In 1560, she gave birth to a daughter, Kamehime.
During this time, he had started an affair with Lady Saigo. In 1573, one of Tsukiyama"s maid servants, Oman, became pregnant by her Ieyasu.
Seeing this and all of the conflicts that her mother-in-law made against her, Tokuhime sent a letter to his father, telling him that Lady Tsukiyama was conspiring with the Takeda clan against the Oda clan. On 9 September 1579, Lady Tsukiyama was beheaded on the shore of Lake Sanaru, in Hamamatsu.
Her primary grave is at Seiryū temple (清流寺) in Tenryu ward, Hamamatsu.
Her head was sent to Okazaki and interred at Yūden temple (祐傳寺). During the Tenpō era (1830–1844) it was transferred to Hachioji Shrine (八王子神社).
