Yoshida (Urabe) clan taught. Michael Brown of Rhode Island Martial Arts possesses documents showing three families of James Mitose. The first family is from Mitose's father's side. This includes his father, Otokichi Mitose and Otokichi's parents, Kaheiji Mitose, and Kano Kawakami Mitose. The second family, from Mitose's mother's side, includes his mother Kiyoka Yoshida Mitose and Kiyoka's biological father, Sakuhei Yoshida. Sakuhei Yoshida was married to a woman who was not Kiyoka's biological mother. Sakuhei Yoshida conceived Kiyoka Yoshida Mitose with a woman outside of his marriage named Toju Kosho. James Mitose would learn Kosho-ryū from the family of Toju Kosho. It is worthwhile to note that on Mitose's parents' record of marriage, Kiyoka Yoshida Mitose's mother is not named as Toju Kosho. Instead the name Toju Unknown occupies this position of the document. To his students and in his book, What is True Self-Defense?, Mitose described his teachings as those of Japanese style. In the book, Mitose describes methods of Japanese yoga and the tai sabaki principles found in many Japanese arts. His later book, What Is Self Defense? and accounts and photos strongly suggest that, however he got it, Mitose had a background in an Okinawan style. Some modern proponents of Kosho Shōrei-ryū believe that he used an Okinawan art as a vehicle for his teaching of a native Japanese art. The contents of What Is Self Defense? seem to echo those of an earlier book: Karate Kenpo by Mutsu Mizuho (1933). This includes the arrangement of diagrams and photographs; in one case, a photo (of Higaonna Kamesuke) is reproduced entirely. Mitose's book also includes a picture of Motobu Chōki, reproduced from Motobu's book, in a position that usually indicates a student acknowledging his teacher. It is from here that some assume that Mitose was acknowledging Motobu as his teacher. Mitose listed Motobu as a Kenpo master in his book. Mitose is known to have taught only one Kata at his school: the Naihanchi Kata, which also was Motobu Chōki's primary form and the only one featured in Motubu's second book Okinawan Kenpo Kumite Hen. Mitose also taught the use of the Makiwara, a signature Okinawan training method. A thriving Okinawan community existed in Hawaii and Okinawan martial arts training was available there. Higaonna Kamesuke stayed in Hawaii after 1933 with Thomas Miyashiro, and taught classes in Kona. Higaonna had studied under Mutsu and Motobu, and taught Karate
