Grandmaster Tanemura was born with the name Tsunehisa Tanemura on the 28th of August 1947, in the town of Matsubushi, which is located in Saitama prefecture, Japan. Tsunehisa was his given name, but later he took the name "Shoto" meaning the "Law of the Sword". 

His father, Sadatsune Tanemura, was the 17th family head of a Samurai line, whose roots extend to those of the Emperors Uda and Seiwa as well as having blood ties to the famous daimyo of the Sasaki and Takeda families. He was an expert in kenjutsu (the art of the sword) and jukenjutsu (the art of the bayonet), as well as various schools of jujutsu (Shizen Ryu system) and Ninjutsu (Takeda system). Being a very traditional father, Sadatsune introduced his son to the martial arts at a young age. 

Grandmaster Tanemura majored in law and graduated from Hosei University. But instead of becoming a lawyer, he wanted a career that allowed him to be out on the streets using his Ninpo and Jujutsu knowledge to protect and help others. When the Grand Master was just deciding what to do with his life, he was involved in a terrible accident. A truck crushed his tiny car, and the injuries Tanemura sensei sustained (including large pieces of glass in his face) looked so bad, that someone mistakenly reported that he had died. In the hospital, forced to consider that his brief life might soon be over, Tanemura Sensei asked for Heaven's help. He promised to change several selfish things about himself, and dedicated the rest of his life to protecting others and teaching them to protect themselves. 

At the age of twenty-two, he joined the Tokyo Metropolitan Police Department. From traffic cop to detective, his work as an officer enabled him to utilize and test all he had learned in the dojo. His skill was called upon on many occasions, and not once did it fail him. Observing his talent, his superiors allowed Tanemura Sensei to teach Ninpo and Jujutsu to policemen at a special martial arts club. Later, he officially became a professor at the police academy. 

After fifteen years of service, he felt in his heart the need to preserve true martial arts in the whole world (not just Japan). So he resigned his job as a Lieutenant to carry out this mission. Soon after leaving the police department, he founded his Genbukan Ninpo Bugei Dojo and organized the Federation.

On November 28th, 1984, Grand Master Shoto Tanemura started with just a handful of students in his Matsubushi dojo. Now his black belt instructors teach thousands of dedicated martial arts in over 15 countries as well as the Grand Master having personally taught seminars worldwide.

Sensei started his martial arts career in 1976 with the art of Judo on the island of Guam. Upon his father’s reassignment to the US, he studied Kenpo Karate under the legendary Mr. Ed Parker in Pasadena, California.

Sensei joined the US Air Force where he became a Joint Terminal Air Controller - TACP/ROMAD (Recon-Observe-Mark and Destroy).  

In 1989 he was assigned to the Joint Special Operations Command and served in many global operations including operations Just Cause and Desert Shield/Storm and worked with elite forces, such as US Army Special Forces, Rangers, Navy SEALs, Marine Force Recon, and UK SAS & SBS.. 

Sensei Ron also spent much of the early 1990’s as a professional skydiver, teaching and competing around the southern US. This led to him becoming the first US Air Force member permanently assigned as a Military Freefall Instructor (MFFI-275) to the elite US Army's JFK Special Warfare Center & Schools. 

After retiring to Tucson, Sensei worked for Raytheon Missile Systems until the attacks of September 11th, 2001. Because of Sensei’s counter-terrorism experience, he was selected to become a Federal Air Marshal, where he learned law enforcement’s non-lethal techniques of Pressure Point Control Tactics, Pain Compliance techniques, and the Koga System, as well as mixed martial arts from former and current champions. 

In 2003, Sensei found a home in Ninpo and traveled to Japan in 2004 to study with Tanemura-sensei. In January 2006 Sensei Ron, decided to move back to the Tucson area and open the Genbukan Shyakunetsu Dojo

How Are the Martial Arts Taught at the Shyakunetsu Dojo Different?


Ninpo Taijutsu is one of the few surviving complete martial arts systems. This 2,000-year old tradition is ideally suited for personal defense since it requires neither speed nor strength, but relies on angles, distance, interval, and natural movements. 

This allows Taijutsu practitioners that are young or small in stature to use relaxed natural movement and angles to overcome a larger opponent's speed and strength. Movement is refined for grace and naturalness in all actions with power resulting from mere movement and evasion from a simple adjustment of body position.

Ninpo Taijutsu is a complete martial art, and as such, incorporates strikes, punches, kicks, throws, locks, tumbling, concentration, empowerment, and literally an unlimited amount of variations.

A few times a year we will train outdoors; it is important for us to commune in our daily environment and other places we may encounter. The martial artist who trains only on mats or smooth wooden floors is often unprepared for hard falls, bad weather, or uneven terrain. 

In contrast, senior students are comfortable fighting in any environment, and rolling and falling even on concrete or from height in the light or dark. This training teaches one to perform automatically, without having to think about what technique is going to be executed.
