Genkō (元亨) was a Japanese era name (年号, nengō, "year name") after Gen'ō and before Shōchū.[1] This period spanned the years from February 1321[2] to December 1324.[3] The reigning Emperor was Go-Daigo-tennō (後醍醐天皇).[4]
Change of era
1321Genkō gannen (元亨元年): The new era name was created to mark an event or series of events. The previous era ended and the new one commenced in Gen'ō 3. The era name is derived from the I Ching; it should not be confused with the later Genkō (1331–1334), which used a different character for kō (弘, "wide", instead of 亨, "go smoothly.")
July 16, 1324 (Genkō 4, 25th day of the 6th month): Former Emperor Go-Uda's death.
The oldest extant account of Buddhism in Japan, the Genkō Shakusho (元亨釈書), was completed in Genkō 2, whence the era name in its title. The massive project was the work of Kokan Shiren.[7]
