Go-Sakuramachi
Empress Go-Sakuramachi (後桜町天皇, Go-Sakuramachi-tennō, 23 September 1740 – 24 December 1813) was the 117th Emperor of Japan, reigning from 1762 until her abdication in 1771.
Go-Sakuramachi later became a “guardian” to the adopted heir (Emperor Kōkaku) until her death in 1813. Go-Sakuramachi was the last of eight women to take on the role of empress regnant in Japan’s history (see: Suiko, Kōgyoku/Saimei, Jitō, Genmei, Genshō, Kōken/Shōtoku, Meishō)
