Great online English-Japanese dictionary

A friend recommended to me a great online English-Japanese dictionary. It is at http://www.alc.co.jp/. It has the most words in its dictionary of any I have every seen. For example, only one of my 3 dictionaries has the word "biotech" in it, and that one has 6 entries. This dictionary has over 139 entries! Many words that I can not find elsewhere are in this dictionary.

Something I won't translate - how to use it. This is a Japanese web site, so the instructions are all in Japanese. This could be a challenge for anyone who is just starting to learn Japanese. The basics are that you enter the word or words in to the blue box at the top, and click the "英和.和英" button to search on this term. It does look for exact matches for the text you enter, so make sure you spell it correctly.

The other button ("クリア") is just for clear, which you can just as easily do by deleting the text in the box.
