Our Dojo is located at 226 South Broadway in Denver. We have trained in the same location for over forty five years.

The building dates back to 1919 when it was a series of shops, and at one time was a meat market. The meat market sign was visible until a few years ago.

The building became a martial arts studio in 1966, and has been ever since. Sensei Yaguchi became the Chief Instructor in 1972 and remained so until 2016 when he decided to retire.

At the start of 2017 Dale and Ryu took over the business in the same location. Although it's not new, it's a location we have come love and revere. It is an authentic old style Dojo. The history and tradition inspires us to excel in our practice. Come in and see for yourself.
