Long-time Japan resident here. I haven’t travelled outside Japan for quite a while so I don’t have a good sense of how payments work in daily life elsewhere. Here, the big convenience store chains now accept a couple of dozen different types of contactless, swipe, or QR code payments [1, 2, 3 (in Japanese)]. However, cash is also widely used, and many smaller businesses still accept only cash [4, 5 (ditto)].
