I have written about Rikaichan before and how it is one of my favorite tools for reading and learning Japanese. It allows even a someone with a basic understanding of Japanese to read like a pro. Well, for all those who use Google’s chrome, a port has been made called Rikaikun.
Since the current release of Chrome doesn’t handle plugins you will need to install the beta. It will ask you to do this if you try and install the plugin. Give it a try and let me know what you think. I’ve got it downloaded and it seems to work just fine. In fact it was easier than Rikaichan because all I needed to do was one click.
