Sometimes, when you play a JRPG, you encounter new terminology or a unique world for their world-building. It can be a challenge for translators to localize it. Simply using a machine translator may not provide a good answer because the author purposely uses their own terminology.

You need a dictionary of kanji to achieve a better understanding and a good translation. Translator++ supports Rikaikun, which shows the reading and English definitions of Japanese words when you hover over Japanese text in the browser. As a Japanese dictionary, Rikaikun helps you look up only the words you don’t know without losing your place.


  • Switch between words, names, and kanji dictionaries using shift or enter.
  • Enable text-to-speech in the options to hear Japanese words you look up spoken out loud.
  • Press ‘c’ to copy the current word and definitions to the clipboard for making flashcards.
  • Customize how the pop-up dictionary looks and what content it shows.

Rikaikun add-on is available on Translator++ version 5.2.18 onwards, and there is no requirement point; it is free to use. Once installed, the Rikaikun icon will show up on the main toolbar.
