Hohan Soken left Okinawa in 1920 for Argentina to seek his fortune. This was a time during the rising influences of the Japanese Imperialistic expansion and Japanization of the former Ryukyu Kingdom that was abolished in 1868 through 1911 (the Meiji Restoration period). The removal of all associations with the Chinese influence was digarded and replaced with Japanese ideals and thought. Thus when Soken returned to Okinawa in 1955, his original teachings were not influenced by the changes of modernization  of over 35 years to what was now known as Karate. The system introduced by Anko Itosu for school children was taught in prefecture schools and Japanese Univeristies and practice by those, now adult teachers of a very Japanese form of what once was a indigenous martial art of the Bushi Class called Tode. This absence from the westernized and industrial Japan created a "Time Capsule" of ancient fighting techniques and true bushijutsu (ancient warrior martial art) that was foreign to most so called Masters of the day in the mid 20th century. Only those students who trained directly with Soken Sensei received the inner fighting methods of the family kata (forms) passed down by Bushi Sokon Matsumura.
