Emperor Go-Kōgon
Emperor of Japan
Emperor Go-Kōgon (後光厳天皇, Go-Kōgon-tennō; 23 March 1338 – 12 March 1374) was the 4th of the Emperors of Northern Court during the Period of the Northern and Southern Courts. According to pre-Meiji scholars, his reign spanned the years from 1352 through 1371.
This Nanboku-chō "sovereign" was named after his father Emperor Kōgon and go- (後), translates literally as "later;" and thus, he may be called the "Later Emperor Kōgon", or, in some older sources, may be identified as "Emperor Kōgon, the second", or as "Emperor Kōgon II."

Events of Go-Kōgon's life
In his own lifetime, Go-Kōgon and those around him believed that he occupied the Chrysanthemum Throne from 25 September 1352 to 9 April 1371.
In 1351, Ashikaga Takauji briefly returned to the allegiance of the Southern Dynasty, causing the Southern Court to briefly consolidate control of the Imperial Line. However, this peace fell apart in April 1352. On this occasion, the Southern Court abducted Retired (Northern) Emperors Emperor Kōgon and Emperor Kōmyō as well as Emperor Sukō and the Crown Prince Tadahito from Kyoto to Anau, the location of the Southern Court.

Why this record matters
A short description can identify a subject without explaining its stakes. For “Emperor Go-Kōgon”, the useful work is to connect “emperor of Japan” to the records capable of establishing context and consequence.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Sep 17, 2026. The linked authority identifier is Q555465. VIAF identifies the subject as 35807458. The Library of Congress control number is n82139840. 3 of 3 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1338, 1374, 1352 and 1371.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
