Brooklyn Aikido Center


Brooklyn Aikido Center exists and functions as a labor of love — to create an inclusive, challenging, and supportive community for personal development.

Brooklyn Aikido Center: Honshinkan Dojo provides training of both body and mind through the traditional Japanese martial art of Aikido.

Aikido inspires personal development to increase confidence, calmness, and focus. Students develop self-protection skills that are effective and dynamic. Ultimately we aim to help students evolve their ability to assess their interactions with others in real time — to use this ability to make the bad better and the better remarkable.
