i study hakkoryu jujutsu,shorin ryu matsumora kempo karate,kodokan judo,kodokan kateme waza,kobudo,muso jikiden isshin ryu iaijutsu.i started training in these systems at about the same time.it costs a lot of money to test in each of these systems so all the time i trained ,i only could afford to pay for rank in hakkoryu.i have my black belt in that system and since i trained all of them concurrently,my instructor said that when i have the money,he would test me for at least my brown if not my black in a few of these systems.i studied for 12yrs now,and am his assistant instructor.ive tought for about 6yrs.
