Northern Court - Southern Court

Southern Court

The Imperial Court supported by the Ashikaga shoguns was rivaled by the Southern Court (南朝, nanchō?) of Go-Daigo and his descendants. This came to be called the Southern Court because its seat was in a location south of its rival. Although the precise location of the emperors' seat did change, it was often identified as simply Yoshino.

In 1392, Emperor Go-Kameyama of the Southern Court was defeated and abdicated in favor of Kōgon's great-grandson, Emperor Go-Komatsu, thus ending the divide. The Southern Court of the Japanese Imperial Line is nonetheless seen as legitimate. In fact, Northern Court members are officially called pretenders. One Southern Court descendant, Kumazawa Hiromichi, declared himself to be Japan's rightful Emperor in the days after the end of the Pacific War. He claimed that Emperor Hirohito was a fraud, arguing that Hirohito's entire line is descended from the Northern Court. Despite this, he was not arrested for lèse majesté, even when donning the Imperial Crest. He could and did produce a koseki detailing his bloodline back to Emperor Go-Daigo in Yoshino, but his claims and rhetoric failed to inspire anything other than sympathy.
