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.
