Bunna

Bunna (文和), also romanized as Bunwa, was a Japanese era name (年号, nengō, lit. year name) of the Northern Court during the Era of Northern and Southern Courts after Kannō and before Enbun. This period spanned the years from September 1352 through March 1356. The emperor in Kyoto was Emperor Go-Kōgon (後光厳天皇). Go-Kōgon's Southern Court rival in Yoshino during this time-frame was Emperor Go-Murakami (後村上天皇).

Nanboku-chō overview
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) had been established in exile in Yoshino, near Nara.

Until the end of the Edo period, the militarily superior pretender-Emperors supported by the Ashikaga shogunate had been mistakenly incorporated in Imperial chronologies though it was acknowledged that the Imperial Regalia were not in their possession.

This illegitimate Northern Court (北朝) had been established in Kyoto by Ashikaga Takauji.
