I love this. Easy as pie to use and insanely useful. If you want to learn japanese, this is pretty much mandatory. すごく便利ですよ!

The MOST HELPFUL extension imaginable for a student of Japanese. You can read anything without having to pause to look up a pesky kanji you don't know. Rikai also knows a ton of words, even slang, so it's a great instant dictionary too. I highly recommend this extension!!

I just recently started using it and it helps me a lot. Works on jukugo and separate kanji. Excellent! Thanks!

I've been using this for a couple weeks and it's really nice. If you're trying to learn kanji and find them occasionally in your daily browsing, definitely get this. Edit: I've been using this plugin for over a year now and still love it.

Been using Rikaichan on firefox , recently moved to chrome ,Rikaikun for the most part gets the job done although i did notice that there are some memory issues and it slows chrome down .Also there is no name support as of yet.Would be perfect with these improvements.
