On my shotengai there are many cash only shops and some cashless shops right next to it. I've also seen a lot of shops that are cash except for PayPay (presumably incentivized, or maybe they can support it without additional hardware). While it's a bit annoying, it's still better than the alternative (payment monopolies). The only thing that does irk me a little is that JR stations only support swipe, not touch pay for credit cards. I'm a bit undecided if that's just due to legacy hardware or as a subtle nudge to get people to use Suica instead. For Japanese payments, what's far worse is that so many shops and chains continue to have point systems that require their own point cards (and even the ones with apps seem to have awful slow UIs, at least on my iPhone).
