In addition to the previous it’s also worth mentioning that Sensei Akamine travelled several times to China, particularly to the province of Fukien or Fujian, since he considered the best Chinese Kempo was developed in this region. There, Sensei Akamine learned some forms of Kempo that later would inspire him to create his own style of Karate. In addition, he learned aspects of herbalist medicine (treatment with medicinal plants) and Tui-na (medicinal treatment utilizing hand pressure, fingers, massage, and stretching of the muscle).

       Shortly before World War II, Sensei Akamine travelled to Tokyo to take residence and to teach martial arts. There, he attended university to take courses in Anatomy and Physiology, stimulated by the noble intention to learn alternative medicine techniques, such as: Shiatsu (pressure with the fingers), Do-in (to guide and to absorb the Ki) and Kuatsu (techniques of resuscitation and rehabilitation) in parallel with these events, he opened his Dojo which he names Shikan-kan (School of the superior men),
Shikan-ryu, the style. And from the name that he gave to his school and to his style, his nickname Shikan Akamine arose, which became very well known in Tokyo, and the country that would further welcome him, Brazil.

       Sensei Akamine spoke with affection of some friends that he had left in Tokyo, and amongst them Seiken Shukumine (Taido Kyokai), Hideo Tsuchiya (Shudokan), Hiroshi Kinjo (Jukendo) and Kanki Izumigawa (his Goju-ryu instructor).
