Emperor Kōkaku
Go-Sakuramachi, and her brother Emperor Momozono were the last lineal descendants of Emperor Nakamikado. She had one nephew who became Emperor Go-Momozono upon her abdication in 1771. Her nephew's reign did not last long, as he died eight years later after a serious illness with no heir to the throne. A possible succession crisis was averted when Momozono hastily adopted an heir on his deathbed upon the insistence of his aunt. In her later years, Go-Sakuramachi became a "guardian" to the adopted heir (Emperor Kōkaku) until her death in 1813. In the history of Japan, Go-Sakuramachi was the last of eight women to take on the role of empress regnant.
