Best Karate Volumes 5-11 by Nakayama are the "gold standard" for JKA Shotokan Kata. Each volume covers several kata. Several camera angles are provided along with embusen and foot position. Rythm notation is also provided. These are a must have reference for any student. You can actually learn kata from these books once proficiency in the fundamental has been reached. Vol 5 is recommended for 8th-3rd kyu. Vol 6-8 is recommended for 3 kyu-1st dan. The unfortunate thing about this set is that Mr. Nakayama passed away before producing a volume containing Jiin and Wankan

'Bunkai: Secrets of Karate Kata Volume 1: The Tekki Series

This Book by Elmar Schmeissar contains complete and continuous kata interpretation for all three Tekki kata. The performance of each movement is shown along with a visualization of continuous applications against an opponent. This book is an eye opener that sheds new light on the Tekki series. Various striking and grappling applications from the kata are shown.

by Shojiro Sugiyama.

I like this book in that it packs 25 kata into one volume with directions in 3 languages! Instead of using pictures, he uses drawings of a little man transitioning through the movements. At first I found it a little hard to understand but once you get used to it, it's not bad. The only thing that would make this book better is if it were called "26 Shotokan Kata"
