Many businesses still don't even accept credit cards. A Japanese airline can get you to any corner of the globe without a hassle, so long as you're paying in cash, even if the tickets come up to a few thousand dollars each (and I wish I wasn't speaking from experience). This is made even more difficult by the fact that I don't think I've ever seen a 24-hour ATM anywhere in Japan.

That's right; most banks in Japan keep their ATMs indoors, which means that once the banks close (typically around 6 p.m.), so do the machines, utterly defeating their entire purpose for existing. It's another extension of that technological resistance -- pretty much anywhere outside of Tokyo harbors a deep generational resentment for automation. They don't want the ATMs operational while there aren't any bank employees around to help in case something goes wrong (although outside of users being clubbed with a thermos and robbed, the list of possible mishaps is embarrassingly short). You can always try an ATM at a convenience store (the number of which currently exceeds the national population), if you don't mind the variable transaction fees that seemingly change at random. And that's only if your ATM card will even work in machines outside of your bank, which it almost certainly won't.
The damn thing even looks like a 1980s fever dream of the future.
