It is an extremely rare book introducing Wado-ryu Karate Kata.Fortunately,it comes with 3 Dvds(region code 2).
Otsuka Hironori taught Karate at Tokyo University for more than 40 years.It is published and supervised by Tokyo Universtiy and is a non-commercial publication.It is distributed only for members.There are very very few copies left.
According to the preface to this book,Otsuka Hironori didn't like to take photos of Kata or to explain it verbally.Tokyo University published some Karate books under license from Otsuka Sensei.However those books are sold out and so new edition was published.
In my opinion,it would be very very difficult( or might be impossible) to obtain it again.This is a must-have item if you are interested in Wado-ryu Karate.
