In less that one year, we get a second amazing book by Hatsumi Sensei. While focusing on stick fighting with ROKUSHAKU BO (six ft long staff) and JO (5 ft walking staff) this book also offers the reader insight into current lessons the ninja grandmaster is teaching in Japan. The photographs illustrate the text though showing flow and direction. Once again, I am very impressed by the photography. This book is both a useful text for students and a work of art for the collector. A fine addition to your ninjutsu library.
