Events of Kameyama's life In 1258, he became Crown Prince at age 9.

Other names Emperor Kameyama had were: Kongogen (金剛源) – his name as a monk Zenrinji-dono (禅林寺殿) – Literally "Lord Zen-Temple" From the fact that he had a Zen temple in the north wing of his Imperial Villa Madenokō-ji-dono (from his residence) Bun'ō Kōtei (From the era name; Kōtei is another word for Emperor) The name Kameyama comes from the location of his tomb.

9 January 1260 (Shōgen 1, 26th day of the 11th month): In the 14th year of Go-Fukakusa-tennōs reign (後深草天皇十四年), the emperor abdicated; and the succession (senso) was received by his younger brother. Shortly thereafter, Emperor Kameyama is said to have acceded to the throne (sokui).

In 1263, during the Kamakura Rebellion, the 6th shōgun, Imperial Prince Munetaka (eldest son of Emperor Go-Saga) was recalled from Kamakura to be replaced by his son Imperial Prince Koreyasu (age 2).

In 1265 a delegation sent by Kublai Khan, ruler of the Mongol Empire, arrived. On its way to Japan, they looted islands. The Mongols invited Japan to submit to the rule of Kublai. The Emperor and the Imperial Court suggested compromise, but they were ignored by the shogun in Kamakura. The Mongol delegation was sent back.

In 1274, abdicating to his son, Emperor Go-Uda, he began his reign as cloistered emperor.

During his time as cloistered emperor, the Mongols invaded the second time. Kameyama personally prayed at the Grand Shrine of Ise. On 15 August 1281, Kameyama-Jokō asked for Amaterasu intervention on behalf of Japan.

However, the Bakufu watched Kameyama with suspicion, and in 1287, encouraged Emperor Go-Uda to abdicate, and pushed for the enthronement of Emperor Go-Fukakusa's son, who became Emperor Fushimi. Kameyama's cloistered rule was suspended by this.

Later, Imperial Prince Hisa'aki, Emperor Go-Fukakusa's son, became shōgun strengthening the position of the Jimyōin-tō. This caused Kameyama to become despondent, and in 1289 he entered the priesthood, joining the Zen sect. Because of this, Zen Buddhism slowly penetrated into the Court Nobility.

In 1291, he helped establish the Buddhist temple Nanzen-ji in Kyōto.

In 1305, he died. Emperor Kameyama is enshrined at Kameyama no Misasagi at Tenryū-ji in Kyoto; and this Imperial mausoleum is maintained by the Imperial Household.

Kugyō is a collective term for the very few most powerful men attached to the court of the Emperor of Japan in pre-Meiji eras. Even during those years in which the court's actual influence outside the palace walls was minimal, the hierarchic organization persisted.

In general, this elite group included only three to four men at a time. These were hereditary courtiers whose experience and background would have brought them to the pinnacle of a life's career. During Kameyama's reign, this apex of the Daijō-kan included:
