for those of you that can read japanese, i like to use this site for lyrics, i'm sure there are other good ones. but this one has good information not just about lyrics
http://music.goo.ne.jp/
if you want to copy the lyrics from this site, when you are on the lyrics page, select all (win: ctrl + a / mac: cmd + a) copy (win ctrl + c / mac: cmd + c) and then paste it into notepad/textedit etc.. you can then copy the lyrics from this. it gets around the protection the site has for copying lyrics.
enjoy
