In 1656, it was named Yashima Gosho (Yashima Imperial Palace) after moving to Yashima Village, Sonokami-no-kori County, Yamato Province, which was donated 200 koku (55.6 cubic meters) (later increased to 300 koku (83.4 cubic meters)) and Sen-ryo (a thousand-ryo) of gold by the government with support of her stepmother, Chugu Tofukumonin (a daughter of Hidetada TOKUGAWA) since the hut was forced to relocate due to building Shugakuin Rikyu (Shugakuin Rikyu Imperial Villa) by Emperor.
明暦2年（1656年）、天皇による修学院離宮の造営によって移転を迫られ、継母である中宮東福門院（徳川秀忠の娘）の助力により、幕府から200石（のちに300石に加増）、金1,000両の寄進を得て、大和国添上郡八嶋の地に移り、八嶋御所と称した。
