A six-seat counter bar. Good whisky, one bartender, no prices on the wall. The bill comes, you reach for a card, and he shakes his head and puts out a small tray instead.
Nothing has gone wrong. Japanese currency law is narrower than visitors expect: it settles what counts as money, and how much of it counts in one payment. It never says what a bar has to accept.
What the currency law actually obliges
Two provisions, and that is the whole of it.
| Instrument | Statute | Legal tender for |
|---|---|---|
| Bank of Japan notes | Bank of Japan Act, Article 46(2) | Any amount. No limit |
| Coins | Currency Unit and Coinage Issuance Act, Article 7 | Up to twenty times face value — twenty coins of each denomination per payment |
The Ministry of Finance gives the reasoning plainly: coins suit small transactions, and a heap of them is a burden to count and store. The limit is not a prohibition — a venue willing to take more may.
That has an edge on a bar bill: three thousand yen in hundred-yen coins is thirty coins, past the limit, and the bar may decline the excess.
Where that rule stops
Beyond those two provisions there is nothing, and the government has said so on the record.
Asked in 2019 whether businesses should be required to accept legal tender, the Cabinet answered on 18 October that those two articles are the only provisions in law on compulsory currency force, and that requiring legal tender to be accepted regardless of what the parties have agreed is not being contemplated, given freedom of contract. Asked whether entering a shop displaying a cashless-only notice amounts to agreeing to it, it declined to generalise: that turns on the circumstances, including whether the customer knew of the condition.
So no Japanese law obliges a bar to take your card. And none obliges it to take your cash either. Cashless-only venues operate here lawfully.
Cash is still the thing to carry, but for a duller reason than a rule protecting it: it has the fewest ways to fail. A note is not declined by an issuer and does not time out on a terminal.
Why a small bar may not take cards
Accepting a card is not free to the venue. Three costs sit behind the terminal: a percentage of every transaction, the terminal and its upkeep, and a wait, because the money arrives days after the drink does. Where one person is owner, bartender and washer-up, none of those is nothing, and the cash box already works.
Scale is the part that gets missed. The Ministry of Economy, Trade and Industry put the cashless share of consumer payments at 58.0 per cent for 2025, ¥162.7 trillion. But it is a ratio measured in yen across all household spending, dominated by wherever the most money moves, and it says nothing about a counter with six seats at it. Roughly two-fifths of consumption is still settled in cash.
The refusal is arithmetic, not attitude.
What to carry, and where to get it
Read the door before you sit. The notice, where there is one, is short.
| Sign | Sounds like | Means |
|---|---|---|
| 現金のみ | genkin nomi | Cash only |
| カード不可 | kādo fuka | Cards not accepted |
| キャッシュレス決済のみ | kyasshuresu kessai nomi | Cashless only — notes will not help here |
| クレジットカード可 | kurejitto kādo ka | Credit cards accepted |
Draw cash before the evening rather than during it. Two networks publish their terms for cards issued outside Japan.
| Operator | Cards marked | Per withdrawal | Hours | Operator’s own fee |
|---|---|---|---|---|
| Seven Bank (7-Eleven) | VISA, Mastercard, UnionPay, American Express, JCB, Discover, Diners Club | ¥100,000; ¥30,000 if read by magnetic stripe | 00:00–24:00 for VISA and Mastercard; the other brands pause 10 to 20 minutes around midnight | Varies by brand |
| Japan Post Bank | VISA, PLUS, Mastercard, Maestro, Cirrus, JCB, China UnionPay, Discover | ¥50,000 | Post office ATMs 07:00–23:00 weekdays, 07:00–21:00 Sundays and holidays | ¥220 for some cards. No balance enquiry |
Published terms as retrieved 29 July 2026. Both operators warn that a card carrying the right mark may still be refused by its own issuer, so these are ceilings, not guarantees. The caps are per withdrawal.
Buying bottles to take home is a different calculation. From 1 November 2026 you pay the tax-inclusive price at the till and reclaim the consumption tax at the airport, so the cash you need in the shop goes up rather than down — see buying whisky in Japan.
What this page deliberately does not tell you
It does not say which bars, streets or districts take cash only, or how many do. Nobody publishes that, it changes, and establishing it would mean walking into each one, which has not been done. A figure invented for the sake of having one is worse than none when you are standing outside a door.
Whether the place in front of you takes a card is a question for that place, asked before you sit down. This describes what the currency provisions cover and what the government has said about their limits. It is not legal or financial advice, and not a recommendation of any card, bank or payment method.
The guide to cover charges covers the other half: what the bill can contain, and why no rule obliges anyone to tell you the figure in advance. The phrase for asking whether cards are taken is in the list there. Both answers are at the door, before you sit.
