Hichibuku Goshinjutsu Genri
I finally got to see a full copy of the Hichibuku Goshinjutsu Genri 秘致武九護身術原理 document written by Takamatsu Sensei. It is not a very large document but contains a number of important principles related to the application and practice of this treatment method.
This relatively small document is part of a larger manuscript: Tatara Hibun 蹈鞴秘文 of which I have only seen an outline for. The Hichibuku Goshinjutsu Genri document follows closely to Chapter 5 of Hatsumi Sensei’s book “Ima Ninja” which I have provided some translation of in English here: Ninpo Used in Daily Life.
