Harold Marion Mitchum is a tenth degree black belt in the Isshin-ryū karate system. He learned under the founder of Isshin-ryū Shimabuku Tatsuo while serving three tours in Okinawa (spanning approximately five years and 10 months) with the U.S. Marines. Though Mitchum himself claims that he was on Okinawa and trained under Shimabuku for seven-and-one-half years this is not the case.
