The Art of Koka-ryu Kempo: True Traditional Budo Training | Martial Arts Fighting Techniques

In this video, I share a brief demonstration on The Art of Koka Ryu Kempo.

[History of the Art, taken from]

Koka Ryu Kempo (甲賀流拳法) was constructed by Soke Anshu Christa Jacobson as a system for self-improvement, self-discipline and self-protection.  Soke Anshu trained in many different kenpo / kempo systems and wanted to compile all of her training into one practice of kempo calling it, Koka-ryu Kempo.  The Art of Koka-ryu Kempo is a direct lineage of Kosei Ryu Kempo which originated from the Shiga prefecture of Japan, also known as Koka.

In 2006 Soke Anshu inherited the art of Kosei-ryu Kempo, making her the 4th Soke within its lineage.  However; since she was already teaching kempo as part of the Budo Ryu Kai curriculum, she had to make a choice.  To either cut out all of the kempo teachings that are not Kosei-ryu, and only teach the Kosei-ryu methods, or to take the art of Kosei-ryu Kempo that she inherited, and combine it with her other kempo training and experiences.

Soke Anshu decided to combine all of her kempo training, principals, and strategies together under the Budo Ryu banner; constructing the art of Koka-ryu Kempo.  Since Kosei-ryu came from the Shiga prefecture of Japan, and it’s the fundamental base of the Budo Ryu kempo curriculum, it is only fitting to have named the kempo training Koka-ryu Kempo which translates out as: “Koka School of Fist Fighting”.

This lesson is directly for the practitioners of the ancient Japanese koryu martial arts of the ninja and samurai, such as ninjutsu (ninpo) and bujutsu (budo).

Search for Historica Shurikenjutsu – 手裏剣術

Historical Ninja and Samurai researcher Antony Cummins is researching the origins of the historical shuriken.  Where there is a problem is in all of the major text of ninjutsu; they do not mention that shuriken at all.  The Bansenshukai, Ninpiden or the Shoninki has no mention of the use of shuriken at all.

So why is the shuriken attached to the ninja if it is not found in any of the historical text?
Can anyone help with any information on this topic?
