Michael Rogge is a Dutch banker (retired, I presume) whose YouTube page includes films of old Hong Kong in the 1950’s and Japan in the 1950’s and 1960’s.
There’s a great video titled “Everyday life in bygone days in Tokyo, 1966 昭和東京“, which was filmed by a German camera crew, according to the description. It is a patient, intimate look at life in 1966 Tokyo, following people to their work, shopping, and into their homes. It includes aerial views of Tokyo, including footage of the shinkansen. It’s well worth watching.
