About the ages of Black Belts: I myself am almost 16, and about to go for my second dan. I have been training for 8 years now, and the youngest Black belt in my Dojo was 11, and there was only one. She started when she was , and has been training hard ever since she was 4. She does very good Kata's and has a lot of focus. However, she did not get her Shodan for being Cute and little!!!, she routinely fights the adults, and sometimes wins. < >>
