Although Japan unofficially uses the Gregorian calendar (e.g. 2014), they also use their own official calendar system which is based on regnal eras (the reigns of their Emperors). These are expressed as "Era + year". So for example 2014 was "Heisei 26", the 26th year in the era of Heisei, the reign of Emperor Akihito. In 2019, Akihito abicated and the Reiwa era began.
