I got the link to this website from “hisako” on Twitter.

This is a website that helps English speakers learn some common expressions in Japanese that you would hear from different characters in anime and manga. What I think is really neat about this website is that it demonstrates some of the different levels of Japanese speak according to different types. For instance the butler using honorifics from the humble perspective. The lessons are given with kanji, kana, or romanji (roman letters) and in spoken Japanese.
The website is still under construction, but check out what they’ve got so far. I’m pretty excited about this and I hope they expand it such that who ever wants to can easy learn basic Japanese in a fun way :).

I wish the flash is downloadable . . . . and copy-pastable . . . . it was indeed helpful but . . . I wanna see it even when I have nothing to do at work (it might be mistaken for a game x_x)
I don't know why but this reminded me of a subbed (crappy) anime that i watched, a character there was saying (subbed of course)”BAKA! BAKA! I am so stupid, i should..”
I was saying, who on earth subbed this?? why didn't he just translated the word?? and it he continues it throughout the episodes.
And don't forget the infamous “all according to keikaku” …
This site has an awesome and helpful goal behind it, but i hope it wouldn't lead to lazy/odd translations because it is a “common” anime/manga phrase.
