Extension summary

As a Japanese dictionary, rikaikun helps you look up the only the words you don't know without losing your place. It's also useful for Japanese speakers wanting to know how to say Japanese phrases in English.

Features:

  • Using shift or enter, switch between word, names, and Kanji dictionaries.
  • Enable text to speech in the options to hear Japanese words you look up spoken out load.
  • Press 'c' to copy the current word and definitions to the clipboard for making flash cards.
  • Customize how the pop up dictionary looks and what content it shows.

Activate the extension by clicking the 理 icon in the top right. When the introductory pop up appears, rikaikun is ready for action.

When it's activated, when you hover over Japanese words they'll be translated in a pop up. If you hit shift/enter, you'll see some information about the first Kanji.

yani hoşuma gitti ancak keşke sadece Japonca metinleri İngilizceye çeviriyor bunun yerine Türkçe vb. dillerde çevrilebilse güzel olur

For me it worked perfectly until recently. Now it does not work at all. I am not sure of the reason. I changed the size and colour of mouse pointer (because I sometimes lost track of it on the screen). I really wish it worked like it did previously.
