Our Ohana

More Than a Gym.
We're Family.

Knightmare Jiu-Jitsu is a family-owned and operated academy right here in Honolulu, Hawaii. Founded by Coach Seung and his family, we've built a place where keiki and adults alike can grow through the art of Brazilian Jiu-Jitsu.

We believe every person who walks through our doors becomes part of our ohana. Our coaches — including Jr. Coaches Abby and Junie — bring patience, knowledge, and genuine aloha to every class.
