There have been many claiming the mantle of James Mitose’s Kosho Ryu, and Bruce Juchnik and Nimr Hassan have been two of the most prominent. In this thread on Martial talk, John Bishop provided links to four Youtube videos that provide recordings of discussions between these two men regarding what they learned from James Mitose, and the direction they planned to take Kosho. Juchnik was a Tracy black belt who met Mitose while he was in prison serving his sentence for his part in a murder conspiracy. Nimr Hassan was the one who (as Terry Lee), was convicted of the actual murder of Frank Namimatsu.
These debates have quieted slightly with the increased activity of Thomas Barros Mitose, who has assumed the defacto head position of Kosho.
These discussions offer invaluable insight into the background of today’s Kosho. I’ve embedded them here after the jump, but the relevant discussion is at Martialtalk.
