For almost a century, Brazilian Jiu-Jitsu has been considered the most efficient and effective martial art in the world and over the last decade BJJ has experienced explosive growth in popularity and participation as the world has witnessed its effectiveness throughout the global media.

For men, women, and children, with or without any previous martial arts experience, we welcome you to explore what Brazilian Jiu-Jitsu training at Kimura BJJ Boston is all about: self-defense, improved health and fitness, competition, stress relief, and camaraderie with like minded people in a supportive environment.

At Kimura BJJ Boston, ego is left at the door and all of our students contribute to a cooperative learning environment for all, supporting each other so that every student benefits as they advance their own learning. At Kimura BJJ Boston, our advanced level students very often join in our beginner classes to share their experience and knowledge with newer students and to help them accelerate their learning and development. These concepts of unity, cooperation, peer support, and advanced practitioners training alongside beginners, are just a few of the many characteristics that make Kimura BJJ Boston so unique.

We welcome you to our unique Kimura BJJ Boston culture of unity, camaraderie, and BJJ excellence.
