Not so much a pocket book, due to its size. Initially I thought I was just buying a Dictionary on Karate & Japanese words, not so, I was really surprised when I received it - the book is neatly broken down into 22 chapters separating all the different kicking, blocking, striking & punching techniques (waza) for ease.
As well as that the Dojo Kun & Niju Kun are also listed.
Other interesting sections include "Vital Points & the Body", Kata, Competition Terminology, Rank & other useful Japanese words used in the dojo.
Pleasantly presented & easy to read & find the information you're looking for very quickly.
Ideal for beginners & the experienced alike, especially a must for instructors as a quick reference.
It ought to handed out for FREE when you join your club IMHO!
I see no reason why it could not be used equally well by other Karate Styles; Goju-ryu, Wado-ryu etc.
