Les Pereira On this page you will find links to two publications on Shihan Jan De Jong (O.A.M.)
and Tsutsumi Ryu Ju Jitsu. We were lucky enough to meet John and his
family shortly after our arrival in Perth. He did much to help us in
our early years in Australia. John passed away in 2003. My family and I
were honoured to be part of the celebration of his life.
