In 1924 Toyama Kanken moved his family to Taiwan where he taught elementary school and studied related systems of Chinese Ch'uan Fa ( kempo/kwan-bop ), which included Taku (Hakuda in Japanese language ), Makaitan, Rutaobai, and Ubo. Taku is one of central China's Hotsupu (northern school) Ch'uan Fa and is further classified as Neikung Ch'uan Fa (Shorei Kempo), that is, an internal method. Makaitan and Rutaobai, which the techniques of nukite (spear hand) came, and Ubo, all belong to the Nampa (southern school) Ch'uan Fa and are external methods or Waikung Ch'uan Fa (Shorei Kempo). These later three styles hail primarily from Taiwan and Fukuden, China. Toyama sensei was also known to have studied and taught Tai Chi Ch'uan Fa. Koyasu sensei studied t'ai chi from Toyama.
