Keishôin was a member of the Ôoku of Shogun Tokugawa Iemitsu, and mother of Tokugawa Tsunayoshi.

She was born in 1628, the second daughter of a Nishijin grocer. In her childhood, she was called Tama. She was later adopted by Honjô Munetoshi, steward for Kanpaku Nijô Mitsuhira. Traveling to Edo as the result of some interaction or connection with O-Ume, daughter of Rokujô Yûjun (a member of the Ôoku), Tama entered the Ôoku herself as a concubine of Shogun Tokugawa Iemitsu, and eventually gave birth to Tokugawa Tsunayoshi, who would grow up to be Shogun himself. After Tsunayoshi became Shogun in 1680, she took up residence in the san-no-maru (third bailey) of Edo castle, and came to be known as San-no-maru-dono as a result.

In 1702, she rose to the Junior First Rank, and many members of her family, beginning with her (adoptive) younger brother Honjô Munesuke, enjoyed the benefits of serving as direct shogunal vassals. It was around this time that her Buddhist devotion grew stronger, and she eventually took on the Buddhist name Keishôin.

She died in 1705, at the age of 79.
