Nitpick: "judo" and "jujutsu" are already heavily used terms. Googling around for information about this, at least for me, is pretty difficult. Judo is an international olympic sport, jujutsu is one of the most famous traditional japanese martial arts, jiu jitsu is the most popular submission base for MMA...

I'd love a rebrand or rename in order to avoid having to work around the name collision.

Best of luck!
