Learn How to Join the OneHeart Challenge
If our work speaks to you, learn how you can join us in the Challenge.
Much More than a Black-Belt Test
Join a team of like-minded karate students as we embark on a journey through the OneHeart Challenge, a year-long quest rooted in the principles of of Isshinryu Karate–the ‘One-Heart Way.’ While some will use the challenge as part of their next rank promotion, it is so much more than a black-belt test. This challenge embodies the harmonious fusion of mind, body, and spirit.
Join us in the spirit of Isshinryu, where for us, the journey to black-belt becomes a quest to bring our practice Out of the Dojo and Into the World.
