I started Brazilian Jiu-Jitsu when I was 50 years old. At the gym I attended at the time, a Jiu-Jitsu class was added once a week, and that was how I first encountered the art.
I became deeply fascinated with Jiu-Jitsu and, at the age of 55, transferred to Carpe Diem Jiyugaoka to begin training seriously. After five years of consistent effort, I earned my black belt.
Because I started later in life, I have always trained with careful thought and intention. In my teaching, I focus on helping beginners—including those with little athletic experience—improve steadily and safely, without injury.
Let’s enjoy Brazilian Jiu-Jitsu together.
Instructor
Koji ImanariKoji Imanari is a black belt in Brazilian Jiu-Jitsu with over 20 years of experience. He began training in Brazilian Jiu-Jitsu in 2003. The following year, at the age of 31, he traveled alone to Brazil, where he immersed himself in intense training alongside high-level competitors. After returning to Japan, he has worked for many years as both a competitor and an instructor in Brazilian Jiu-Jitsu and grappling. He is known for providing clear, logical explanations, practical advice, and up-to-date techniques—not only for beginners, but also for advanced practitioners and professional athletes.

Nice to meet you. My name is Koji Imanari, and I’m an instructor here.
I started Brazilian Jiu-Jitsu at the age of 30, without any prior martial arts experience. I don’t have a competition record that I would boast about, but I was fortunate enough to earn my black belt.
Of course, starting early is great—but starting later is absolutely not a problem.
Through Jiu-Jitsu, I’ve met countless people and witnessed many unforgettable moments. If I hadn’t started training 20 years ago, I honestly can’t imagine where my life would be today.
I hope to help make your life richer through Brazilian Jiu-Jitsu in whatever way I can.

I began training in martial arts at the age of six at a combat sports gym run by my father. From a young age, I experienced wrestling, judo, and Brazilian Jiu-Jitsu, which shaped my approach to martial arts.
Today, I focus on creating an environment where everyone - from complete beginners to those aiming to become competitors - can enjoy learning Brazilian Jiu-Jitsu.
The more you train, the deeper and more fascinating Jiu-Jitsu becomes. It’s an art that truly pulls you in. I hope you’ll experience that excitement for yourself.
If you feel that you’re "not athletic" or think martial arts might be intimidating, please don’t worry - just come and try it.
You may discover a new passion or goal.
