Japanese to Western Calendar Conversion

Convert Years from Japanese to Western Calendar

Most Japanese use, and are familiar with, the Western calendar (seireki). However, the traditional Japanese calendar (nengō, literally, year name) is a common calendar scheme used to count years and is often used for official documents.

The traditional Japanese calendar is based on the periods of the emperors’ reigns. When a new emperor takes the throne a new era begins and the new ear acquires a new name.

Emperor Akihito is set to abdicate on April 30, 2019, which will make him the first Japanese Emperor to do so in over two centuries. This will mark the end of the Heisei Era. The new era will most likely be named on April 1, 2019.

To convert a Japanese year to a Western year use the charts below.
