Another source of Japanese era information with more data has been created by myself mainly based on Wikipedia research: https://github.com/MenoData/Time4J/blob/master/calendar/src/test/resources/d... It serves as base of my Nengo-implementation: http://time4j.net/javadoc-en/net/time4j/calendar/Nengo.html You have also to be aware of a coming new Japanese era on 2019-05-01. But the name of the new era is not yet decided and will be proclaimed any time this year to give the administration and the calendar makers some time, see also: https://www.tagesspiegel.de/politik/neue-aera-ab-2019-japans-kaiser-akihito-...

Would the tz project be interested in keeping track of the Japanese Era information?
glibc currently stores it as part of its locale data, but I think this causes some issues (particularly with downstream builds).
Thanks, Florian
