Forgot one, since I haven't needed to use it in a while.
If your computer doesn't have Japanese fonts installed, you can use this filter to redisplay a page with graphics replacing Japanese characters. It works surprisingly well, but slow connections will have trouble. Just change the www.yahoo.co.jp
to any link you want.
Mod Edit: Link seems to be dead. Can't seem to find a working Shodouka on Google either. Maybe it will come back one day.
