Genbun

Genbun (元文) was a Japanese era name (年号) after Kyōhō and before Kanpō.  This period spanned the years from April 1736 through February 1741. The reigning emperor was Sakuramachi-tennō (桜町天皇).

Change of era

 * 1736 Genbun gannen (元文元年): To mark the enthronement of Sakuramachi, the era was changed to Genbun (meaning "Original civility"). The previous era ended and the new one commenced in Kyōhō 21, on the 21st day of the 4th month.

Events of the Genbun era

 * 1736 (Genbun 1): The shogunate published an edict declaring that henceforth, the sole, authorized coinage in the empire would be those copper coins which were marked on the obverse with the character 文 (pronounced bun in Japanese or pronounced wen in Chinese—which is to say, the same character which is found in this era name of Genbun).
