I have practised ninjitsu with ninja instructor Arie Van Den Akker. The Kuroi ryu Ninjitsu style the grandmaster is Ashida Kim i supose. I quit ninjitsu because i was to bussy with school. We did many outdoor training, blowguns, stances, sparring, locks, groundfighting, weapons, stealth. It was a bit ju jutsu like, but with pressure nerve points. And many more, But i am very interested in brazilian ju jutsu, does anyone know more about that?
