Tools to Help Read Japanese Web Pages
Plugins for Firefox, Chrome or Safari
Rikaichan (Jonathan Zarate) *** Highly Recommended *** Free *** A Firefox plugin that has similar features to (see below). You can put your cursor over any word on the resulting page to get the reading and the English meaning. If you haven't yet upgraded to Firefox (It's free), then this is a very good reason to do so. ADVANTAGES: This even works offline. There is also a word lookup (dictionary) function that makes many of the other EDICT dictionary lookup programs obsolete. For example, you can enter "飼っている" and it will find "飼う" for you. This means you can copy and paste things "as is" to get meanings.
Rikaikun - For Chrome and does about the same thing as "Rikaichan" does for Firefox.
Rikaitan (for Safari by Jordan Hill) - You'll have to search for it within Safari. I can't link to it.
Jim Breen's WWWJDIC Server - Text Word Translation Input Japanese in the form (or enter a URL) and get a page generated with all the words looked up for you already. One important advantage this one has over the next one is that you can print the results to paper, then read the text away from a computer (while commuting, etc.).
(Todd Rudick) Enter a URL, then put your cursor over any kanji on the resulting page to get the reading and English. (This didn't work with some browsers I tested it with.)
(Alex Schonfeld) This is similar to . However, it has the advantage of working with more browsers.
OFFLINE? WordChamp's Web Reader You don't need to register, so just ignore that part. This doesn't recognize various verb conjugations like and do. Try Charles Kelly's Bilingual English-Japanese Random Sentence Generator via WordCamp (The direct link is Bilingual English-Japanese Random Sentence Generator - 英日文章自動生成プログラム ).
The rest are for reading help (hiragana or romaji) only, no English definitions.

Adaptive Technologies' Furigana Web Page Converter You don't need to register or have a password, so just skip to the bottom of the page to enter a URL. FEATURE: You can even get Romaji furigana, if you want. This makes it very easy to see what was not on the original page.
Kakashi Web Front End: Read Japanese Websites in Romaji (Joel Yliluoma) Converts web pages from Japanese characters to Romaji.
