간인노미야가의 막내 황자로서 원래 도모히토 신노가 슈고인 사에서 사제로 들어가는 것으로 예상되었다. 그러나 1779년 아들없이 죽어가던 고모모조노

Kōkaku was very talented and had a zeal for scholarship, reviving festivals at the [[Iwashimizu Shrine|Iwashimizu]] and Kamono shrines, and working hard at reviving ceremonies surrounding the Imperial Court. The Bakufu gave his father the honorary title of Retired Emperor ([[Daijō Tennō]], 太上天皇). Genealogically, Kōkaku is the founder of the dynastic imperial branch currently on the throne. Kōkaku is the lineal ancestor of all the succeeding [[emperors of Japan]] up to present monarch, [[Akihito]].
One of the emperor's personal physicians during this period was [[Tachibana Nankei]], also known as Miyagawa Shunki and as Iwami-no-kami . He traveled for five years before being appointed the emperor's personal physician.<ref>Screech, p. 224 n116.</ref>
During Kōkaku's reign, the Imperial Court attempted to re-assert some of its authority by proposing a relief program to the [[Tokugawa shogunate|Bakufu]] at the time of the Great ''[[Tenmei]]'' Famine (1782-1788) and receiving information about negotiations with [[Russia]] over disputes in the north.
