The Japanese era system identifies a year by the combination of the era name (Gengou or Nengou) and the year number within the era. For example, A.D. 2001 is Heisei 13. Please note that two Gengou schemes were used in Parallel from 1331 to 1392 during Nanboku-chō period.

This application would be very useful if you are working with the governments, municipal offices and/or certain companies in Japan.

User Reviews

I believe this is the same app I had a few years ago when it was free, and I liked it then. I still like it, but there’s a UI problem. On my iPhone 8 running the latest version of iOS, when I try to tap the settings button, it just scrolls the year. It looks like the year scroller overlaps the settings button and is on top of it. When this is fixed I will like this app very much.

I have used the app for a few years, but if it isn't updated to 64-bit the app is basically useless.

Simple app does exactly what it's supposed to do, conveniently... but needs an overdue compatibility update to continue being supported in future releases of iOS.
