Query: Best Japanese Book ever.

I can't stand doing boring work. I have very little patience and I lose interest in studies easily. This is the ONLY Japanese book I've ever finished. Why? It kicks ass from beginning to end.Seriously, if you want to learn Kana, this is the book for you. It starts with a good explanation of the why/how/what of these two syllabaries. Then it goes right into hiragana but doesn't overwhelm you. After you've been introduced to enough material, you get a review. (There are tons of reviews and they all cover word examples that are practical to know for cultural or historic events.) Once you've completed hiragana, the book moves on to katakana. The system builds upon itself and the two syllabaries make sense the way they're presented in this book.I started this book back in XMAS 2003. Three months later, I know both kana syllabaries like the back of my hand.Best Japanese purchase EVER.
