Gunji Koizumi (1885 - 1965) arguably one of the most famous Judoka, in British history, a Chinese lacquer expert by trade and master of Tenshin Shinyo Jujutsu, Kenjutsu, Akishima Ryu Jujutsu and Katsu. He was only to stay for a year, training and instructing his martial Arts around the country, notably at the Kara Ashikaga Jujutsu school, the Piccadilly School of Jujutsu, the RNVR, etc. until he decided to journey to the United States. He did, however return in 1910 and eventually founded the London Budokwai, in 1918, offering Jujutsu, Kendo and other Japanese arts to the British public. A year later Koizumi asked Tani to join him as an instructor at his school of Martial Ways and Tani accepted, retiring from his Music Hall bouts.
