Events of Kōmyō's life In his own lifetime, Kōmyō and those around him believed that he occupied the Chrysanthemum Throne from 20 September 1336 to 18 November 1348.

When Ashikaga Takauji rebelled against Emperor Go-Daigo's Kenmu Restoration and entered Kyōto in 1336, Go-Daigo fled to Enryaku-ji on Mount Hiei. Despite lacking the sacred treasures, Prince Yutahito was enthroned as emperor, beginning the Northern Court. On the 12th month, 21st day, Go-Daigo escaped to Yoshino, founding the Southern Court.

On 18 November 1348, he abdicated in favor of the eldest son of his older brother, the former claimant to the throne Emperor Kōgon, who became Emperor Sukō.

In April 1352, taking advantage of the Kan'ō Disturbance, a family feud in the Ashikaga clan, the Southern Emperor Emperor Go-Murakami entered Kyoto, capturing it and carrying away Kōmyō along with Emperor Kōgon, Emperor Sukō, and the Crown Prince Tadahito. They all ended up finally in Anau, the location of the Southern Court.

In the Shōhei Reunification, Kōmyō and his companions were placed under house arrest in Yamato Province, in what is today the village of Nishiyoshino, Yoshino District, Nara. In 1355, returning to Kyōto, he entered a monastery.

26 July 1380 (Kōryaku 2, 24th day of the 6th month) : The former emperor died at age 60.
