Three Life-Changing Benefits of Training Kyokushin
Unshakable Mental Strength
USA Kyokushin Karate pushes you to face challenges beyond your comfort zone. Through rigorous training and contact fighting, you develop resilience, focus, and the ability to remain calm under pressure — both inside and outside the dojo.
Discipline and Character
The spirit of USA Kyokushin Karate is built on respect, humility, and perseverance. Daily training instills discipline that extends into every aspect of life, shaping character, responsibility, and a deep sense of integrity.
Health, Confidence, Power
USA Kyokushin Karate is not just martial arts — it is a complete path to health. Students gain strength, endurance, flexibility, and vitality. As the body transforms, so does the mind, leading to lasting self-confidence and the courage to face life’s obstacles.
Philosophy of Teaching Kyokushin
My students are known for their exquisite form. I believe that true Kyokushin power does not come from sheer effort alone — it comes from the repetition of perfect form. Effort makes you winded and limits your potential, but perfect form allows you to move comfortably, accelerate through a longer distance, and generate far greater force.
As physics teaches us, force = mass × acceleration. By accelerating through a longer distance with precision, you unlock explosive, impulsive power that far exceeds brute strength.
I have had the privilege of learning from some of the world’s greatest Kyokushin masters, and with my scientific and medical background, I have developed a method that helps students achieve supple, controlled, and devastatingly powerful technique.
Testimonials
“One of the best things that ever happened to me was meeting Dr. Bomi Joseph. At 62, his energy is absolutely infectious. Training with him and the Kyokushin fighters has been life-changing — these are some of the toughest martial artists I’ve ever seen. Kyokushin has made a huge difference in my life, helping me focus, grow, and stay strong. ”

My Story
My journey began in May 1975, when I first met Sosai Mas Oyama at the Hotel Okura in Tokyo.
In the summer of 1979, I traveled to Japan and joined the Honbu Dojo in Ikebukuro, where Sensei Goda was my chief instructor. I dreamed of becoming an Uchi Deshi and even told him I wanted to quit school for Kyokushin. Shihan Goda spoke with Sosai Oyama—who, after testing my resolve, sent me back to medical school, saying:
“Kyokushin needs a doctor. We have enough ruffians.”
Later, I trained in London under Shihan Steve Arneil, and after completing school, I moved to New York in 1982. There, I was thrilled to discover a Kyokushin dojo in Manhattan, led by Soshu Shigeru Oyama. His Uchi Deshi, Sensei Hioki and Sensei Kenji Fujiwara, became my instructors.
When Sensei Hioki relocated to Phoenix, he entrusted me to his best friend, Shihan Fujiwara. From 1986 to 1992, I trained with Shihan Fujiwara in Bethel, Connecticut—seeking tournaments, challenges, and every opportunity to test myself in true Kyokushin spirit.
In 1992, I moved to California with Shihan Fujiwara and opened our own dojo in Campbell, CA. Since then Shihan Fujiwara moved back to Connecticut and then Japan. The dojo, that used to be the backyard of my house, has grown immensely. It has graduated numerous black belts and today stands as the Honbu (Headquarters) of Kyokushin Karate in the United States.
