I’m very pleased to present this interview with Bill Hayes, Kyoshi of Shobayashi Karate-do. Hayes Sensei became a senior student of famed Okinawan instructor Eizo Shimabukuro and has worked diligently to pass along karate as it was originally taught to him over the course of multiple decades.

Hayes Sensei is a retired Major of the United States Marine Corps, having served two active tours of duty in Vietnam as well as three tours on Okinawa. He is often considered the “complete package” of Okinawan Karate, embodying Okinawan culture, diligent wellness, strong character, and technical transcendence.
Hayes Sensei is the author of the book “My Journey With the Grandmaster“, a work not originally intended for public consumption but now a staple in many traditional artist’s libraries. Hayes Sensei also publishes a quarterly newsletter containing rare bits of history and wisdom accrued over many years of research and study.
These days Hayes Sensei heads the Okinawa Shorin Ryu Karatedo Kenkyu Kai Shobayashi-Kan, a semi-private research group that he uses to guide students in a very personal way that mirrors the core essence of his original training on Okinawa.
I recently had the chance to sit down with Hayes Sensei and ask him a wide variety of questions, ranging from his personal experiences to matters of technique, as well as philosophical issues in present day training. I hope you enjoy the following videos, broken into topical sections.
