I thought the book was excellent, it provided easy to follow pictures for not only techniques, but also for etiquette. It also contained each Koryu-No-Kata technique on a separate page, which is very unique. Each technique was easy to follow, with step by step pictures as well as detailed explanations. As there are not many books out there on this subject, I believe that this is a must for every student of Kenji Tomiki's system and those people who are curious about aikido in general. Furthermore, there was a great section on the history of aikido which was very informative.
