She was born in Kyoto, the daughter of Dainagon Seikanji Hirosada, and was brought at a very young age to Edo to meet her aunt, who was a concubine to Shogun Tokugawa Tsunayoshi. She was adopted by Tsunayoshi in 1708 (at age 3), and was engaged to Matsudaira Masakuni, lord of Aizu han, and then to Prince Arisugawa Tadahito, but both died before they were married. Tsunayoshi, along with Konoe Hiroko (wife of Tsunayoshi's heir Tokugawa Ienobu) and Renjô-in (one of Ienobu's prominent concubines), then made a proposal to Shimazu Tsugutoyo, which was resisted (on account of fears that Tsugutoyo would die as her previous fiancées had), but ultimately accepted. Tsugutoyo and Takehime were betrothed, and after Takehime was formally adopted by Tokugawa Yoshimune, the two were married on 1729/12/11. She gave birth to a daughter, Kikuhime, in 1733, and raised Shimazu Munenobu as her adopted son as well.
