History
The calendar was created in 425 during the Genka era in Chinese history.Japan, Monbushō. (1876).  An outline history of Japanese education: prepared for the Philadelphia International Exhibition, 1876, p. 160.

The  Genka-reki system was brought to Japan from Korea by a Buddhist monk.Needham, Joseph. (1959).  Science and civilisation in China, Mathematics and the sciences of the heavens and the earth, Vol. 3, p. 391 note d.  The earliest record of this calendar in Japan is in the 10th month of the 10th year of the reign of Empress Suiko (602).

Dates in the Nihon Shoki before the late 7th century were likely recorded using the Genka calendar system.Barnes, Gina Lee. (2007).  State Formation in Japan: Emergence of a 4th-Century Ruling Elite, p. 226 n.5.
