Mr Tani was knowledgeable not only in jujitsu, but also in rokushakubo and hanbo (types of staff fighting), horseback riding, sumo wrestling and kenjutsu (Japanese swordsmanship). Tani’s brother and another fighter named S. Yamamoto also arrived to teach at The Golden Square Dojo (Edward Barton Wright’s school) but left after a year to return to Japan. Tani and his fellow jitsuka Uyenishi (who had also returned to Japan before The Unstoppable Letty Pegg begins) ended up leaving a lasting mark upon England, being two of the first to bring jiu jitsu to Western Europe.
