This is the most advanced, comprehensive, convinient Japanese English dictionary app. It is a-must-have for beginers as well as advanced Japanese leaners.

The unique feature of this application is that the meanings of the words you look up are displayed immediately. We have also taken time and effort to write the meanings of tens of thousands of words so that many people can easily understand. The content of your review is factually incorrect and misleading to many people. Please remove this review.
