Honbu Dojo Denver, Colorado
Classical Jujitsu, Traditional Karate and Tai Chi Chuan — Nagai Ryu, Shin Go Ju Ryu and the Chen style — preserved through ancestral kata, unbroken lineage, and selfless instruction. A sanctuary of physical mastery and stillness.
The Budo Standard
We are not a commercial school. Nobody here draws a wage for teaching, every dollar goes back into the mat, and the reason the doors open on a Wednesday night is that somebody once taught us for nothing.
Direct pedigree passing through Professor Matsuyama, Ueshiba O Sensei, Mifune Sensei, Shihan Goody and Sifu Gene Chen. We preserve uncorrupted kata, bone-deep structural alignment, and realistic combative leverage.
Yama Arashi Ryu is a non-profit. Every dollar that comes in goes straight back into the school — the mat, the space, the equipment. Not one of our black belts takes a wage for teaching. There are no contracts, no sales staff, and nobody here whose livelihood depends on signing you up.
Our teachers were handed this art by people who asked nothing for it. Teaching is how that debt is paid: giri, the obligation to pass on what was passed to you. It is why the mat is staffed on a weeknight by attorneys, civil servants, software engineers and craftsmen who did a full day's work first — people who average thirty years in the art, and more than forty-five at the senior grades.
