Someone interested in Kanō Jigorō's visit of Germany in 1933, could, for example, search for the article
"Exzellenz wirft jeden Gegner - Bericht über den Besuch von Baron Dr. Jigoro Kano in Berlin"
from "Berliner Illustrirte Zeitung".
Unfortunately I don't know the exact date at the moment. But I know, that most photos in this article in fact were taken earlier in June, at the open-air rooftop-dōjō of the "I. Oesterreichischer Jiu-Jitsu-Klub" in Vienna, where Kanō-shihan demonstrated together with Takasaki Masami and Kotani Sumiyuki:
Nevertheless, there is also a picture of Kanō-shihan talking during a "SA-Sportfest" with SA-Gruppenführer Hans von Tschammer und Osten (at this time "Reichskommissar für Turnen und Sport" since April 28th, 1933), who shortly after this conversation was appointed "Reichssportfuehrer" (July 19th, 1933).
BTW, did you all know that a "Jiu-Jitsu-Griff" allegedly once even saved Hitler's life?
According to the memoirs of Ernst Hanfstaengl, a sponsor of Hitler since the early 1920ies, it happened in November of 1923. After the abolition of his attempted coup, Hitler, hidden in Hanfstaengel's villa, tried to escape the impending imprisonment by shooting himself. When Hanfstaengl's wife Helene (nee Helene Elise Adelheid Niemeyer), "stormed up the stairs to Hitler's garret, the latter entered the anteroom of his hideout with a revolver pulled out. 'This is the end', he shouted, 'to let imprison myself by this pigs - never! Rather dead!'. But before he was able to walk the talk, my wife already had applied the effective Jiu-Jitsu-lock of the police-officer from Boston¹, and the revolver went flying in a big arc into a barrel standing there at some distance, and was rapidly buried under the stock of flour within.
If the story is true, it changed history radically. Or, perhaps better, without this intervention by Helene Hanfstaengl history would have been changed radically.

¹ After school Hanfstaengl emigrated, studied at Harvard until 1909, and later lived in New York for some years. After WWI, when his "Hanfstaengl-Kunstsalon" - the New York branch of the parental company in Germany - already was confiscated by the US-administration as "property of a foe", he returned to Germany.
