During those years leading up to Pearl Harbor, the Japanese gave way to a weird megalomania of a kind that has affected other peoples from time to time. This was simply the belief that everything had originally been invented in Japan: the first bicycle and the first sewing machine, radios, escalators, and electric toasters. You name it, the Japanese had made the first one, only to have their brilliant idea pinched and exploited by the West (exactly the opposite, of course, of how the West then viewed the Japanese). But I never heard any Japanese lay claim to a first that was undoubtedly theirs: talking pictures. These were being featured in Japanese movie theaters at least ten years before Hollywood startled the world with Al Jolson in The Jazz Singer .
