Tōhito , posthumously honored as Emperor Momozono , was the 116th emperor of Japan, according to the traditional order of succession. Momozono's reign spanned the years from 1747 until his death in 1762. Momozono's reign was mostly quiet, with only one incident occurring that involved a small number of Kuge who advocated for the restoration of direct Imperial rule. These Kuge were punished by the shōgun, who held de facto power in the country.

Toshiko , posthumously honored as Empress Go-Sakuramachi was the 117th monarch of Japan, according to the traditional order of succession. She was named after her father Emperor Sakuramachi, with the word go (後) before her name translating in this context as "later" or "second one". Her reign spanned the years from 1762 through to her abdication in 1771. The only significant event during her reign was an unsuccessful outside plot that intended to displace the shogunate with restored imperial powers.
