When I was younger, my older brother had a large Brazillian mate who was really into martial arts and japanese traditionalism.
The guy was very experienced with Juijitsu in its traditional and in it's Brazillian forms. But because of his love for japanese culture he practised more Ninjutsu and Ninpo. He had some pretty sick ass traditional Japanese weapons, christ knows how he got his hands on most them.
But yeah, they used to practise on me [V] if that counts as having any martial arts experience, then I probably have more experience than most...
