Do you actually get a cash discount? If not then doesn’t seem worth it.
Not a cash discount per se, but specifically no extra fees. If the bill says (for example) ¥35,000, then ¥35,000 is exactly what I would pay in cash. If I were to pay with credit card then I would also have to also have to pay the +3.3% (or however much) in credit card processing fees. Someone has to pay Visa’s credit card processing fees (and that someone is always going to be me, lol).
And I see someone else’s (Robert.Walter’s) reply to Boeingfan where Robert suggest that there an extra admin burden or a risk of loss or mistakes associated with cash. I don’t know how it works in Australia with Boeingfan, but in Japan there are entire national processing systems involved with certain types of bills and cash payments. Once you pay in cash (at one of the 100,000 or so locations that you can pay in cash), there is an instant digital record of it (as well as an instant physical record of it). You can get certain bills from anywhere in Japan and pay for it in cash at any of the previously mentioned 100,000-ish locations.
And all of this is so very quick. From start (handing over the bill) to finish (getting a physical record of your payment back), that could take just 20-25 seconds or so. (IDK, I’ve never timed it.) Maybe even quicker if you wanted to try to ‘speedrun’ bill paying, lol.
Please note that with any of these bills that I am specifically talking about, I could quickly scan into an app and pay for it at home using whatever non-cash payment method. That’s definitely an option and it’s a similar process. Although you don’t get a physical record of your transaction — in that case it would be fully-digital.
I don’t want to make it seem like it’s cash or nothing. There are definitely many other payment methods. It’s just that cash payments (for the specific type of bills I’m describing) are super easy and incredibly convenient to do in Japan (and with no extra fees). It’s also basically the only time that I do use cash in Japan, lol. For everything else (whenever possible) I’ll use credit card, Apple Pay, Suica, PayPay or whatever other digital payment method.
