The Warrior Scholar Mindset
Before you look at what the Academy offers, consider whether this describes how you already think about your training.
You value study over status. Rank and recognition matter less to you than actually understanding what you practice.
You believe principles come before technique. A movement means little to you until you understand why it works.
You see martial arts as a lifelong pursuit. You are not looking for a program to finish, but a study to continue.
You care about preserving authentic teaching. You would rather learn something correctly, and completely, than quickly.
You understand that character is built through disciplined practice, not claimed through a belt or a title.
If this describes you, you are already a Warrior Scholar.
The Academy exists to give that mindset a place to continue its study.
The Academy
The Home of Hanshi Bruce Juchnik's Teachings
Warrior Scholar Academy exists to preserve, organize, and teach the body of work Hanshi Bruce Juchnik has developed over decades of study in Kosho Ryu Kempo.
Rather than a catalog of unrelated courses, the Academy is organized as a path of study: beginning with the Chronicles, continuing through structured training, and extending into advanced work for practitioners ready to go further.
Hanshi Bruce Juchnik
A Lifetime of Study, Preserved and Continued
Hanshi Bruce Juchnik leads Warrior Scholar Academy. He is the 22nd inheritor of Kosho Ryu Kempo, passed to him directly by James Mitose, and serves as director of Sei Kosho Shorei Kai International.
His study of the art has continued for decades, shaped by direct instruction from Mitose and by teachers including Robert Trias, who personally entrusted him with preserving material from his own line before his passing.
Warrior Scholar Academy exists to carry that same responsibility forward, preserving, organizing, and teaching this body of work for current and future generations of practitioners, rather than simply adding to a catalog of courses.
The purpose is not to give you one more system to collect. It is to help you continue studying with greater depth, context, and understanding.

The Kosho Chronicles Study Membership is the continuing education program of Warrior Scholar Academy, built for practitioners who understand that study does not end at any rank. Each week, members continue examining the principles, history, and philosophy of Kosho Ryu through the ongoing teachings of Hanshi Bruce Juchnik, in the company of others still asking the same questions. This is where that practice continues.

What the Academy Exists to Preserve
Warrior Scholar Academy exists to preserve, organize, and teach the body of work developed by Hanshi Bruce Juchnik over more than five decades of study in Kosho Ryu Kempo.
This is not a catalog of courses to complete. It is a living tradition: principles tested through practice, history preserved through study, and teachings carried forward for practitioners who have not yet begun.
Every Chronicle, every course, and every department within the Academy exists in service of that same purpose: to make sure this work continues to be understood correctly, and continues to be taught.
