One thing that goes with Japan is the US Navy. They have a few bases around here but the biggest one is Yokosuka.
Yokosuka has been a port for ships for hundreds of years. It is where the West and East finally came together. Now the men and women that live here and serve in the US military have a chance to train Jiujitsu and experiance what it is like to live in a foreign country and train with people that love the same sport.
Please check out this short film by Andy Barker. It details the opportunity that the U.S. Navy community has to connect with their friends in the Martial arts community.
