Report an issue"Gengou Lib." is a quick reference of the Japanese era system. This application has functions as below.
- Era and Year Search - Period picker - Era picker - Christian era year picker - Japanese era year picker - Show this year button - Texts can be shown in Japanese or English independently of the default language setting. - Application badge can show this year number in the Japanese era or the Christian era.
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.

8 of 17超必要これ！日本語版作ってくれるの？ローマ字じゃなくて。。。 I sooooo need this living in Japan! You Rock!
最高〜〜〜!!!
Good job . It helps Japanese lives in US too long.
Nothing fancy here... clean, simple, and gets the job done. Great reference tool. Wish I'd had it when I lived in Japan!
As other reviewers have noted, this app lets you convert between gregorian and japanese era calendars. It does this by presenting two spinning wheels (one with the western year, the other with the japanese year) which are locked to one another - you can spin either one and the other will turn to match, letting you look up the corresponding date. Of course, you *could* do this in your head, especially for the most current era (heisei) since you always know what the most recent year of the era is, but once you start getting into past eras, it becomes increasingly difficult unless you have the exact years of the emperor's death and the length of their reign memorised, something which most Japanese, especially young people, do not. For this reason, most Japanese day planners come with a small conversion chart in the back for reference. If you live in Japan and have such a chart you probably won't need this application but if not, and you find yourself needing to convert between the two calendar systems, it can be quite handy. At any rate, it's free, so you can't go wrong!
I hate doing conversions in my head. Kudos!
It was always difficult figuring out the Japanese year period. This app helps out soooo much.
Clean. Simple. Great job!
