I can't say anymore this book is exclent. it has diagrams and is verry informative. just be sure to buy th required equitment.
While it should go without saying that no martial art can be learned solely from a book and that the intricacies need to be experienced with a real live teacher in real time, I think that this book can definitely benefit students of Eishin Ryu Iaido. Whether you are a beginner, trying to remember the waza (techniques), or an old hand, looking to brush up on the basics that can get lost over time, Suino's book is a good reference text.
I have to say that I was surprised. So many martial arts texts either have amateurish pictures (such as Yang Jwing-Ming's texts, which are otherwise so useful) or pictures that simply don't include enough details. This book has basic but clear graphics that, along with real-life/real-time instruction, make a lot of sense. Even Suino's description of how to put on the gi and hakama are better than most I've seen. (If he included how to fold the hakama, it would be even better! Luckily, you can get that online ([...]).)
Compared to a book like Flashing Steel, Suino helps the beginner in particular by focusing on the pragmatic topics: he lists and explains the introductory Batto Ho no Bu (Drawing Methods Set) techniques, the intermediatesd Tatehiza no Bu (Half-Seated Set), and the advanced Tachiwaza no Bu (Secret Forms, Standing Set). While the glossary could be longer, you can filter through the text to find other words/phrases that he uses and explains and pencil them into the glossary on your own.
The other thing that really excites me about this book is that he always includes the kanji (Japanese characters) for the names of the techniques. As an intermediate speaker of Japanese, that helped me a lot when I was trying to figure out what the names really meant.
