While traveling through Japan, my two sons and I had the opportunity to participate in a Shorin-ryu karate class led by Ryo Wakabayashi. Having trained in ITF Taekwondo, I expected familiar movements with a different uniform. Instead, I walked away with a renewed appreciation for the value of learning outside my own discipline.
One of the first differences I noticed was how Shorin-ryu used the legs defensively. In ITF Taekwondo, we’re accustomed to using our feet as offensive tools—fast kicks delivered from a greater distance. During the karate class, however, the instructors emphasized lifting the knee and using the leg to check, redirect, or absorb incoming attacks before immediately transitioning into a counter. It was a subtle difference, but one that expanded how I think about movement and defense.
“The more you know, the more you realize how much remains to be learned.”

The second lesson was breathing. Every technique was synchronized with deliberate breathing. Rather than simply generating power through speed and body mechanics, each movement was connected to controlled inhalation and exhalation. The breathing created rhythm, stability, and focus, making every technique feel intentional rather than rushed. It was a reminder that efficiency often comes from mastering fundamentals instead of adding complexity.
As someone who works in operations and Lean leadership, I couldn’t help but connect these lessons to continuous improvement. Lean teaches us that improvement rarely comes from believing we already have the best process. It comes from observing, asking questions, respecting different approaches, and remaining willing to learn. Visiting another martial art was much like benchmarking another organization. You don’t abandon your own system, but you often return with ideas that make your own practice stronger.
Whether on the training floor or in the workplace, growth requires humility. There is always another perspective that can sharpen your skills if you’re willing to become a student again.
Of all the experiences we had in Japan, this karate class will remain one of my favorites. Sharing the mat with my sons, learning something completely new together, and encouraging one another through unfamiliar techniques reminded me that the best lessons are often the ones experienced side by side. Long after the techniques fade from memory, I’ll remember the privilege of learning together as a family.
