Shorinjiryu Karate is a dynamic, expressive, effective and unique form of budo. It has a richness of technique, history and practitioners, yet there are relatively few books and other media available on our style.
To the best of my knowledge, only a handful of books have been published to date - three in English, one in Japanese and one in German. There have also been a couple of training manuals written by some individual schools of Shorinjiryu, and there are a couple of books on Koshiki Karate - the competition system developed by Hanshi Masayuki Hisataka of the Kenkokan.
All of the published books are out of print, and this is a shame because these are important resources for practitioners of our style. A great piece of news is that two books on Shorinjiryu are now available from Amazon as Kindle eBook editions. This means they will be resources readily available to current and future generations of Shorinjiryu karateka.
Of particular interest is the Kindle edition of Scientific Karatedo, written by Hanshi Hisataka (my former teacher), and first published in 1976, with a 2nd edition in 1995. In my opinion, this is one of the most comprehensive and valid books written on karate - full stop. For Shorinjiryu practitioners, this is an important resource, with detailed information on many of the kata (including Naihanchin Dai, Nijushiho, Happiken, Bassai and Seisan), yakusoku kumite and bukiho practices of our style. It is a must have feature of every practitioners library.
Also authored by Hanshi Hisataka is the Kindle edition of Essential Shorinjiryu Karatedo, which was first published in print in 1994. This book is almost completely based on a manuscript co-authored by Hanshi Hisataka and myself during my years in Japan (1991-93). We worked very closely together on this book for over 2 years. It contains a huge "brain dump" of Hisataka Sensei's impressive personal knowlege on the techniques of karatedo, as well as extensive historical information which we jointly researched. After the final manuscript we did jointly, some additional material of a religious nature was added, and some original material on history and one kata (Seisan) were omitted. Aside from these aspects, Essential Shorinjiryu Karatedo should also be part of every Shorinjiryu practitioners library.
eBooks are a great way of having the wonderful information available in these books. Apart from the fact that previously hard to get books are now available, eBooks are always available (on your computer, smart phone or tablet), and are environmentally friendly (no trees killed, and less resources spent in getting them from the printing press to you).
