Rare photo of Emperor Hirohito signing the Japanese unconditional surrender

I am indebted to Fergus Butler-Gallie for this photograph, which he captions as "the time the leader of WWII Japan and sometime God-Emperor, Hirohito, was loomed over threateningly by Mickey Mouse on a visit to Disneyland". My title is of course completely untrue.

Or is it? Surely there is something of the humiliation of defeat on display here? 

It is not the done thing nowadays, at least not outside China, Korea or Singapore, to dwell on the behaviour of the Japanese during the Second World War; if we were to do so then perhaps we would feel that the humiliation of defeat was only right and fitting. On the other hand, I would not be surprised if there were young Japanese men who have copies of this photograph hanging on their walls, next to photographs of Nagasaki and Hiroshima, and who daily swear to avenge the indignities visited on their country by the land of Mickey Mouse.
