Fair point. Is there any way of finding out what films/general readership books etc. were popular at the time? Maybe the publishing houses of the day (if any survive) have a list of best sellers. This might be a way to get an idea of what was going on in popular culture at the time. Like, I’m not a film person, but I do recognise the names of popular films atm and have an idea of what they’re about even though I’ve never watched them and probably never will. Even current tv shows might give some idea of what was popular - that is, if tv was around in that area at that time. Would shinto religious observance be useful source of info about probable life experience? Or other customary observances that are traditional to that general area? I’m thinking of the tree-threatening ceremony, for orchard growers.
