Fumio Manaka (martial name "Unsui") who has sixty years experience in the classical Japanese martial arts (Kobudo), founded the Jinenkan in 1996 to allow students to study the martial arts of old Japan freely and unhindered under his guidance. Between 1997 and 2005, Manaka Sensei produced a series of articles for his students dealing with various topics related to the arts studied within the Jinenkan including the techniques, histories and strategies of the various martial Ryuha (lineages). The information contained within these articles had previously been unavailable in the English language and when they were first published, they represented a treasure trove of information for students. This book draws on those original articles to provide information on the most fundamental techniques found within the Jinenkan, together with an overview of the martial Ryuha which are studied. The book is intended for to serve as an introduction to the Jinenkan for newer students but there is plenty within its pages which will be of interest to more experienced practitioners.
