Our History

Kyoshi Noah Mitchell began studying karate at the Sankaku Kyokai karate organization in 1983.

His original karate instructor had studied Shotokan karate under Latino Gonzalez and Goju-Ryu karate under Peter Urban in the late 50s and 60s. He returned from military service in the Philippines and opened the Sankaku Kyokai Karate organization in Yorktown in 1967. His unique system combined traditional Shotokan and Goju-Ryu karate styles. In 1995, Sankaku Kyokai changed hands and became the Watakushitachi-no Karate Association, which lasted until 2006. At Mountain Stream Budo, we will endeavor to perpetuate this unique combination of systems, while helping it to grow and expand, as all healthy budo systems must do in order to improve.

Kyoshi Mitchell teaches Matayoshi-Ryu kobudo, a traditional Okinawan kobudo system. His lineage is tied directly to Matayoshi Shinpo Sensei himself. 

Shortly following Matayoshi Sensei’s death in 1997, Gakiya Yoshiaki Sensei founded his own organization, the Okinawa Kobudo Doushi Rensei-kai®, which is now a worldwide kobudo system. Kyoshi Mitchell's kobudo instructor is Gakiya Sensei’s top student, Hanshi Neil Stolsmark, 9th dan, Kokusai Honbu-Cho, and President of the OKDR.

Mountain Stream Budo is the official New York State branch of the Okinawa Kobudo Doushi Rensei-kai®, and Sensei Noah Mitchell is the New York State Shibu-Cho (branch head).

Mountain Stream Budo is also an official branch dojo of the United States Federation of Battodo and the Zen Nippon Toyama-Ryu Iaido Renmei.

"These days there are many different types of martial arts schools to choose from. Some are more like gyms than traditional dojos. Others are “belt factories” where you earn rank simply by showing up and paying the required amount of money. Mountain Stream Budo is the exception…the “diamond” in the rough. Sensei Noah Mitchell is a true martial artist. He is dedicated to his arts, his students and his dojo. His love for the martial arts is evident in his constant training and continued pursuit of knowledge.

Although Mountain Stream Budo is a traditional school in regard to etiquette, it has a relaxed atmosphere that allows for interaction between students and teachers in a way that fosters growth. There is incredible attention to detail in all that is taught. The bar is set high and the teachers at Mountain Stream Budo require proficiency from their students. Students who attain rank at Mountain Stream Budo have earned it, just as their instructors have.

Whether you are interested in traditional karate from Okinawa, jujitsu or sword arts (battodo) from Japan, or the weapons art of kobudo, Mountain Stream Budo offers superb instruction. If you would like to become a skilled martial artist under the watchful eyes of truly experienced teachers…if you want the rank you obtain to really mean something, then study at Mountain Stream Budo."

Sensei Chris Cardillo, Rising Phoenix Martial Arts

"I am currently a student at Mountain Stream Budo in jujitsu and karate, and also assist in the Lil' Dragons program. After finishing college, I found myself in that uncertain place most 20-somethings find themselves. I walked into MSB in early February of 2009 looking for a interesting way to stay in shape that didn't involve running endlessly on a treadmill in a gym full of muscle-heads. I was always interested in martial arts but never had the guts to just do it. And the first thing I noticed about everyone at this school was how nice and accepting each person is. There is no judgment based on physical ability or stature. There is a warm and welcoming atmosphere and everyone feels like family. MSB has allowed me to meet some diverse and amazingly talented people, and great new friends.

The actual instruction is an experience like no other. At MSB, you do not just learn how to kick and punch. It is a complete immersion into a way of life. It's more than just a physical education, it's also a mental and philosophical education. You learn not just self defense, but Japanese language, a bit of culture and history, and life lessons. This all-encompassing instruction is due to the school's diverse Sensei. Each has his or her own interpretation of martial arts and specific teaching style that results in a well-rounded education. They all provide great workouts, and each has his own intense form of physical conditioning. My favorite part about training at MSB is the physical as well as mental challenges that keep me alert, curious and in shape. "
