Is this something you'd watch? Would it be something you'd be interested in? Would it be helpful? I'm a bit on the fence.
Absolutely! I was just looking at this sort of thing as I got on a bit of a "Yankee in Japan" youtube kick a while back. I then looked at a few "Yankee in UK" vids to compare.
This was all very un-scientific, but I sensed some trends.
I noticed, and again I just sampled four or five US/UK vlogs, that the American in Japan vlogs often centered around things like walk-throughs of the apartment, neighbourhoods and shops, etc.
The US/UK vlogs, and again I just watched the top search results for things like "American in England", seemed to be more so personal interviews/man on the street kinds of things.
I would guess language has something to do with this. But it resulted in a situation where I noticed "cultural cringe" in the US/UK vlogs. They ended up going down the old route of Yanks are idiots/Brits are weird.
Now I must say that it seemed to me that the US/UK vlogs seemed more student based, where as the US/Japan vlogs were more worker related.
But I really like the US/Japan ones where they demonstrated say the rice cooker....or the walk up to the train station or the local 7-11's selection of exotic snacks. Something about some of them were triggering the tingly/ASMR/Bob Ross effect....just the showing of everyday things in a new environment.....
Anyway, very unscientific I know....
