If young people anywhere would see floppies, I'm guessing Japan would be more likely than a lot of other places. They're notoriously slow about getting rid of old tech. I think Sony was still making VCRs until 2016, and faxes were ubiquitous even like 10 years ago.

I saw people in the mid 2000s plug in USB floppy drives so they could work with whatever records they still had on floppy. I have no idea why that was easier for them than just putting the files on a USB drive.
