Koketsu Kai, Tiger's Den Martial Arts

Koketsu Kai, Tiger's Den Martial Arts Here at the Tiger’s Den we teach jiu-jitsu and Kenjutsu. The number of forms or Seiho is small and learning the basics is easy.

Our Jiu-jitsu system is a traditional based self defence style called Jukoshin Ryu Jiu-jitsu and our Kenjutsu is Niten Ichi Ryu. Jukoshin Ryu Jiu-jitsu
Jukoshin Ryu Jiu-Jitsu was founded by Soke Bryan Cheek, (10th Dan Jiu-jitsu, 8th Dan Kobudo, 7th Dan Judo) in 2003. Jukoshin Ryu Jiu-jitsu is recognized as a modern western martial art, with Japanese origins, and is accepted as such by the International Society of Headfounders and Headmasters. Jukoshin Ryu - Spirit of Gentle and Strong - Jiu Jitsu is now playing a major role in the family of martial arts, this is due to its very practical, efficient and no nonsense techniques, devised over some 30 years by Soke Bryan Cheek. With its emphasis on the 5 S's - Skill - Speed - Stamina - Suppleness and Strength, this system appeals to students that require a self defence strategy that really works. Jukoshin Ryu also provides a variety of techniques second to none, which enables all types of students the ability to succeed, and to become proficient in this combat art. Throws - Locks - Pressure Points - Strikes - Kicks - Grappling and weapons training are all inclusive in the vast syllabus available. It uses many traditional techniques, which have been tried and tested, and also many modern combat formulas, which make this style progressive yet proven. A uniform standard of training around the world is required of all participants within Jukoshin Ryu, with particular emphasis on all Dan gradings. These are monitored and controlled by the International Grading Committee consisting of members from ten different countries, ensuring a worldwide standard at Black Belt level. Niten Ichi Ryu Kenjutsu
Kenjutsu is the umbrella term for all (koryu) schools of Japanese swordsmanship, in particular those that predate the Meiji Restoration. The modern styles of kendo and iaido that were established in the 20th century included modern form of kenjutsu in their curriculum, too. Kenjutsu, which originated with the samurai class of feudal Japan, means "the method, technique or the art of the sword." This is opposed to kendo, which means "the way of the sword"

Specifically the style of kenjutsu we teach, Hyoho Niten Ichi-ryu, is that developed by Miyamoto Musashi in the early 1600s. This style teaches techniques for the Tachi or long sword/katana, Kodachi or short sword/ wakizashi and Nito or two swords (one long sword and one short sword). Perfecting the forms/seiho on the other hand can take a lifetime. Students begin by learning the twelve long sword forms, than the seven short sword forms and finally the Nito or two sword forms.
