The Southern Court (南朝 Nanchō ) were a set of four emperors (Emperor Go-Daigo and his line) whose claims to sovereignty during the Nanboku-chō period spanning from 1336 through 1392 were usurped by the Northern Court. This period ended with the Southern Court definitively losing the war, and they were forced to completely submit sovereignty to the Northern Court. This had the result that while later Japanese sovereigns were descended from the Northern Court, posterity assigns sole legitimacy during this period to the Southern Court.
The genesis of the Northern Court go back to Emperor Go-Saga, who reigned from 1242 through 1246. Go-Saga was succeeded by two of his sons, Emperor Go-Fukakusa and Emperor Kameyama, who took turns on the throne. This because on his death bed in 1272, Go-Saga had insisted that his sons adopt a plan in which future emperors from the two fraternal lines would ascend the throne in alternating succession. This plan proved to be unworkable, resulting in rival factions and rival claimants to the throne.
Go-Fukakusa's descendants were referred to as the Jimyōin-tō (持明院統) while Kameyama's descendants were known as the Daikakuji-tō (大覚寺統).
In 1333, when Emperor Go-Daigo (from the Daikakuji-tō) staged the Kemmu Restoration and revolted against the Kamakura shogunate, the Shōgun responded by declaring Emperor Kōgon, Go-Daigo's second cousin once removed and the son of an earlier emperor, Emperor Go-Fushimi of the Jimyōin-tō, as the new emperor. After the destruction of the Kamakura shogunate in 1333, Kōgon lost his claim, but his brother, Emperor Kōmyō, and two of his sons were supported by the new Ashikaga shoguns as the rightful claimants to the throne. Kōgon's family thus formed an alternate Imperial Court in Kyoto, which came to be called the Northern Court because its seat was in a location north of its rival.
During the Meiji period, an Imperial decree dated March 3, 1911 established that the legitimate reigning monarchs of this period were the direct descendants of Emperor Go-Daigo through Emperor Go-Murakami, whose Southern Court (南朝 nanchō ) had been established in exile in Yoshino, near Nara.
These are the Hokuchō or Northern Court emperors:
- Emperor Kōgon 1332-1333.
- Emperor Kōmyō 1336-1348.
- Emperor Sukō 1348-1351.
- Emperor Go-Kōgon 1352-1371.
- Emperor Go-En'yū 1371-1382.
- Emperor Go-Komatsu 1382-1392 (then went on to reign as legitimate emperor 1392-1412)
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 Go-Daigo in Yoshino, but his claims and rhetoric failed to inspire anything other than sympathy.
Southern Court Emperors
These are the Nanchō or Southern Court emperors:
- Emperor Go-Daigo 1336-1339.
- Emperor Go-Murakami 1339-1368.
- Emperor Chōkei 1368-1383.
- Emperor Go-Kameyama 1383-1392.
Re-unification of Imperial Courts
Go-Kameyama reached an agreement with Go-Komatsu to return to the old alternations on a ten-year plan. However, Go-Komatsu broke this promise, not only ruling for 20 years, but being succeeded by his own son, rather than by one from the former Southern Court.
