2. sensei studied a few arts. the most well known arts he studied were as follows:
growing up he studied "the controvesial" dux ryu. he as the youngest black belt and was the fastest to get promoted in the dux ryu's history. becoming disillusioned with dux's illusions(hee hee! that one made me laugh
) he went on to look for another more effective art. he moved to europe and began to train under dr. roy martina tja kai martial science system. after recieving his ranking there... he went on to go earn his dan's in hapkido. After his stay in europe sensei came back to the states and moved to texas where he became a student of robert bussey's. he became an insturctor under rbwi and then went off to create RTMS.
RTMS has not been around as long as other arts but continues to grow and add to itself to abstain from becoming stagnant (sp?).
3. that i'm not sure of but refer to question 4 for more details why.
4. there is no difference in rtms and tew ryu ninjutsu. tew ryu was a name he gave at the beginning when he first started to develop his art. as the style evolved he got tired of the confusion of many (the whole traditional and modern arguement of the ages) and decided to change the style name to rtms. tew ryu is now what we call the students. we are the ryu... school. a network of students from around the globe. that is why we don't associate ourselves with iga or koga... we are tew ryu.
hope this answers questions for the future.
peace
