In 1995 he met Kato Hiroshi Shihan at Hombu Dojo, soon inviting him to San Francisco to teach his first San Francisco seminar and becoming one of Kato Sensei’s first American students. Friedman Sensei’s approach to Aikido stresses hard training and conditioning with an emphasis on practical application, while retaining a very relaxed physical state. James has an extensive background in highly competitive sports; he received a brown belt (2017) in Brazilian Jiu-Jitsu from Clovis Silva. He brings that intensity and focus into his teaching style in Aikido. Friedman Sensei received the rank of Roku dan (2011) from Hiroshi Kato Sensei.
