I came to a website with an Anime/Manga Japanese-English Glossary. Its good for anyone who likes Anime or is learning Japanese partly because of Anime. I was searching for that and found it off Google. The website is: http://www.flame.org/~calger/animedict.html. Here is the introduction:
"Anime/Manga Japanese-English Glossary
The following Japanese/English glossary is words, phrases and grammar points that are commonly used in anime and manga. This list came about because I like to watch anime in the original Japanese, and over time I started picking up bits and pieces of the language just by listening. One day in a moment of boredom I jotted down what words I could immediately remember (about 100). This glossary really took off when I left to spend a year in Japan, where I studied the language formally and was exposed to the practical everyday use of the language. I learned a tremendous amount, and I've tried to make this glossary as accurate as possible. However I am by no means an expert in Japanese, and so everything in this dictionary should be taken with a grain of salt, as it were.
This is particularly important because Japanese is a very complex culturally-based language with many built-in levels of politeness. If you haven't studied the language yourself, it's easy to make incorrect assumptions about how Japanese used (e.g. the often-incorrect "Fangirl Japanese" rampant in anime fanfiction). The characters in anime and manga are usually friends (or motal enemies) and so use informal language with each other. That manner of speaking is NOT appropriate for a foreigner visiting Japan to use. So, my cautionary note: don't go around using the material in this glossary without formally studying the Japanese language first! The Japanese are pretty lenient about the butchering of their language where foreigners are concerned, but you still don't want to accidently insult anyone -_-;;
There are several systems for transcribing Japanese to the English alphabet. Due to font limitations I've had to spell most words as they're said, so the spelling here may look different from Japanese/English dictionaries you buy in the store. For an example, in this glossary "oni" is said with a short "i"; for "onii" the "i" sound is held twice as long. Long "o" sounds are written as "ou". I've been pretty rigorous in checking out these words and phrases for accuracy, but some meanings still elude me (remember I'm not an expert in Japanese) and I'm sure there are still mistakes in here. If you see any blatant errors or have a contribution, please let me know! :)"
