Toyama certainly had some links to China, for example:
On the far right (no pun intended) is Chiang Kai-Shek, leader of Republican China. I have to wonder, if there were some martial arts exchanges, or discussions regarding fundamental bodyskill training. According to the memoir of one of Chiang's aides, Chen Lifu, Toyama "looked after" Chiang in Japan during a 1927 visit. Chiang was known to have had various kungfu training. In Taiwan, he had a bodyguard cadre trained by the Liu Yunqiao, a high level bajiquan practitioner.
