I want to steer all of you who are SERIOUS about learning Japanese to a very very helpful and useful sight created by a woman named Kim Allen. Here is the site address:

(if that doesn't work try:"http://kimallen.sheepdogdesign.net/Japanese")

I highly recommend this site!! It is very useful, and especially if you're going to visit Japan, you should read about her trips which are located near the bottom of the page, after the language stuff. Oh, and read EVERYTHING:
