Kōtarō Yoshida dating history

Details

Kōtarō Yoshida (吉田 幸太郎, Yoshida Kōtarō, October 1883–1966) was a 19th- to 20th-century Japanese martial artist. There have been claims that Yoshida was a member of the Kokuryukai,
Amur River Society (also known as the Black Dragon Society), an ultra-nationalist organization of disenfranchised ex-samurai who promulgated "pan-Asiatic ascendancy" in line with the rise of Japanese imperialism. Others have asserted that he was a member of the Genyosha (the "Dark Ocean Society'), a previous organization founded by Toyama Mitsuru. However, the membership roles of both of these organizations are meticulously documented, and Yoshida's name does not show up in the registry of either the Genyosha or the Kokuryukai.
Therefore, although it is quite likely that Yoshida had right-wing, nationalist leanings, he was not a significant figure in the major nationalist organizations of the late Meiji and Taisho periods.
