Emperor Go-Kameyama (後亀山天皇 Go-Kameyama Tennō) was the 99th emperor of Japan, according to the traditional order of succession.
He ruled from 1383 to October 21, 1392, becoming the last Emperor of the Southern Court.
His personal name was Hironari (熙成).
This Nanboku-chō "sovereign" was named after the 13th century Emperor Kameyama and go- (後), translates literally as "later"; and thus, he may be called the "Later Emperor Kameyama". The Japanese word "go" has also been translated to mean the "second one"; and in some older sources, this would-be emperor may be identified as "Kameyama, the second", or as "Kameyama II".
