I just want to say two things about this book. Firstly, the book is well-researched to some extent.

However, I need to clarify a few things about Yabu’s Gojūshiho:
- Firstly, the Gojūshiho of Nakazato Shūgorō sensei is not from Yabu Kentsū sensei. Nakazato himself confirmed in a Japanese interview that all his kata came from Chibana Chōshin sensei, except for Gojūshiho, which comes from the Hanashiro Chōmo lineage.
- Secondly, the only student of Chibana sensei who received “Yabu no Gojūshiho” is Miyahira Katsuya, who got the kata via Tokuda Anbun 徳田安文 (1886-1945). Tokuda himself was a student of Yabu Kentsū at the Shihan Gakkō (mentioned by Yamauchi & Nakayoshi).
It also needs to be mentioned that the life dates given by Feldmann for Tokuda Anbun sensei are not correct. (see Page 325)
