Hello: I was looking at www.njoyamakarate.com located in cliffside nj and would like to know if anyone has had any experience with this school. I do not have any previous karate instruction and would like the forum members here to opine on their knowledge of Oyama schools, either in the above mentioned school in nj or in the nyc area. I am mainly interested in the practical self defense/street fighting aspect of the art. Thank you for any information.
