Query: great!!!

This is the best Kendo book I have found so far. A book can not replace real training, but if you are a student of Kendo, or think you might be interested in it, this book can help you mentaly. It covers the basic commands, and Japanese names for the equipment. This book also covers some spiritual side to the art. Kendo: The Definitive Guide by Hiroshi Ozawa is a great reenforcement, and enhancement to a great art. Buy it!
