Just a note on the accuracy of the time period, Yukio Tani began "taking all comers" in London, by 1900 or 1901. He beat virtually all of his challengers with the "triangle choke" or sangaku jime. Only when he couldn't display it did he use other methods, savoring them wisely. The following is from an article, originally printed in *Warrior Dreams* by Graham Noble and today is seen on EJMAS :

"Yukio Tani was never too good with dates, and even the one date he did quote -- September 26, 1899, when he and his brother arrived in London at the invitation of E.W. Barton-Wright -- was wrong. Richard Bowen has established that the two came to Britain in September 1900, and were followed not long after by S. Yamamoto. Yukio Tani was to stay in England for the rest of his life, but his brother and Yamamoto returned to Japan within a year, possibly due to a disagreement on the use of jujutsu as "entertainment."
When Barton-Wright gave his lecture before the Japan Society of London in 1901 he took along Tani and Yamamoto to demonstrate jujutsu technique. They showed the throws and locks of the art and then Yamamoto performed what seems to have been pretty much a standard feat among many of those early jujutsu pioneers. He lay on his back with his hands tied and had a pole placed against his throat. Three men on either side of the pole held it down while two stood on Yamamoto and another two held his legs in position. At a signal these ten men pressed down to prevent Yamamoto moving, but within twenty seconds he had escaped the holds and was a free man.
At the same lecture Barton-Wright gave a demonstration of "locking" on a volunteer from the audience, the six-foot tall Lt. Douglas. "The lecturer," the report read, "a much smaller man than his opponent with the greatest of ease threw him down and in a variety of practical performances illustrated the modes of obtaining victory."
