It's hard to say too much about Michael Jai White, whether you're talking about his talents (seven black belts, dozens of major acting roles, and even more television roles), or him as a person (former special education teacher, also just plain nice).
The first are White began learning was actually jujutsu, but, his first black belt was in Kyokushin karate. This is no doubt an important style to him to this day. So, it's not surprising that one of the ways he would choose to give back to the martial arts community would be teaching to the next generation of martial artists!
