7 hidden fees to watch for at exchange counters in Japan in 2026
Most "0 % commission" signs at Japanese exchange counters are technically true and economically misleading β the shop's profit is hidden in the spread between the displayed rate and the live mid-market rate, plus six other tactics that quietly pad the cost. This guide names every fee mechanism that real shops use, the actual size of each, and how to spot them before you hand over cash. Most of these tactics raise costs by 0.3β2.0 % β small alone, significant in combination.
TL;DR
- Spread markup is the biggest hidden fee, typically 1β4 % built into the displayed rate.
- Minimum-amount thresholds add a tax on small exchanges.
- Denomination penalties kick in on bills under $20 / β¬20.
- Weekend / late-night surcharges add 0.3β0.5 %.
- Old-bill rejection can leave you stranded with a useless handful of cash.
- DCC at card-paid exchanges triggers a second markup.
- Round-down / round-up rules pocket a few yen per transaction β small but cumulative.
#1 β The spread (the biggest hidden fee)
When a shop displays "0 % commission" or "no fees," they're often referring only to a separate line-item commission they don't charge. The shop's actual profit comes from the spread β the difference between their displayed exchange rate and the live mid-market rate.
For USD on a typical day:
- Mid-market: 151.50 JPY
- Average shop "buy" rate: 149.00 JPY
- Hidden spread: 1.65 % = Β₯250 per $100
Compounded across $1,000:
- Β₯2,500 in hidden spread
- Β₯0 in line-item "commission"
- Total cost: Β₯2,500 (which the "0 %" sign quietly omits)
How to spot it: check the live mid-market rate before walking in. If the displayed buy rate is more than 1.5 % below mid-market on USD/EUR, you're looking at a wide spread.

#2 β Minimum exchange thresholds
Some shops add a flat fee on exchanges below a minimum amount. The fee may be:
- Β₯500βΒ₯1,000 on amounts under Β₯10,000
- Β₯200βΒ₯300 on amounts under Β₯5,000
- A worse rate tier (e.g., 1 % more spread) below the minimum
How to spot it: ask "minimum?" before exchanging small amounts. Some shops won't accept exchanges under Β₯3,000 at all.
Workaround: for amounts under Β₯10,000, a 7-Eleven Seven Bank ATM is often cheaper than any shop's small-amount tier. The flat ATM fee (Β₯110βΒ₯220) is fixed regardless of withdrawal size.
#3 β Denomination penalties
Many shops apply a worse rate to small bills (US $1 / $5, β¬5 / β¬10). The reasoning is operational: small bills are slower to count and harder to inventory. The penalty is typically:
- US $1 bills: 5β10 % worse rate than the displayed rate
- US $5 / β¬5: 2β4 % worse
- US $10 / β¬10: 0.5β1 % worse
- US $20+ / β¬20+: displayed rate
How to spot it: the rate board may have a separate column labeled "small notes" (ε°ι‘η΄εΉ£) with worse numbers. If you don't see one, ask explicitly before handing over $1 / $5 bills.
Workaround: consolidate to $20+ bills before flying. Worth breaking your $5s at home.
#4 β Weekend and late-night surcharges
Some 24-hour exchange counters (especially at airports and non-station locations) charge a small surcharge outside business hours. Typical amounts:
- After 8 pm: 0.3β0.5 % wider spread
- Weekends: 0.2β0.4 % wider spread
- Public holidays: 0.3β0.6 % wider spread
How to spot it: rate boards rarely advertise this β it's baked into the displayed rate. The same shop's daytime rate vs night rate should differ on a comparable currency.
Workaround: use a 7-Eleven Seven Bank ATM after-hours instead of a counter. Seven Bank's late-night surcharge is the Β₯110βΒ₯220 ATM fee (a flat Β₯110 difference, not a percentage), much cheaper on amounts above Β₯3,000.
#5 β Old-bill rejection (and "verification fee")
Most Japanese counters won't accept:
- Marked, written-on, or stained foreign bills
- US bills issued before 2009 (older "small portrait" series)
- EUR bills with significant wear or torn corners
- Foreign coins (most won't accept any coins at all)
A few counters will accept "old" bills but apply a verification fee of Β₯500βΒ₯1,000 β effectively a way to extract margin while appearing to help.
How to spot it: if your bills look pre-2010 or have any visible wear, ask the staff before handing over. The "we can take this but there's a small handling fee" line is the warning.
Workaround: bring clean, post-2009 USD bills only. Same for EUR β older designs with even small wear are most likely to trigger penalties.
#6 β Dynamic Currency Conversion at the counter
Some exchange counters offer to convert your card-paid purchase into your home currency at the time of payment β typically with a 5β8 % markup baked into the conversion. This is Dynamic Currency Conversion (DCC).
The flow looks like:
- You go to exchange Β₯100,000 worth of yen for cash
- The counter offers to charge your card in USD instead, "for convenience"
- The card is charged at a rate 5β8 % worse than mid-market
How to spot it: any time the counter or terminal asks "Pay in your home currency?" β say no, choose JPY.
β Article #12: Dynamic Currency Conversion trap.
#7 β Round-down / round-up rules
Smaller-print rule: many shops round the JPY received down to the nearest Β₯100 or Β₯500, while rounding the foreign currency up to the next Β₯10,000 β small per transaction, cumulative across the day.
Example:
- $487 worth of yen at displayed rate of 149: Β₯72,563
- Rounded received: Β₯72,500 (cost: Β₯63)
- Foreign currency tendered: $500 (refund of $13)
The Β₯63 disappears into the shop's margin. Across hundreds of daily transactions, it adds up.
How to spot it: ask the staff to confirm the exact yen amount before handing over your cash. A shop that won't disclose rounding rules is a red flag.
How do all 7 fees stack up in practice?
For a $500 USD exchange at a typical airport counter on a Saturday evening with $100 in $5 bills:
| Cost | Approximate amount | |---|---| | Spread (mid-market 151.50 β counter rate 145) | βΒ₯3,250 | | Saturday late-night surcharge (already in spread) | (included) | | Small-bill penalty on $100 of $5s | βΒ₯150 | | Round-down on receipt | βΒ₯50 | | Total cost | Β₯3,450 (vs Β₯75,750 mid-market) |
That's β4.5 % on a single transaction β about Β₯3,000 above the already-bad airport rate. The same exchange at a Shinjuku West Exit shop on a weekday morning: Β₯1,000βΒ₯1,500 of spread, no other fees.
The single quotable fact: the difference between the worst combination (airport + weekend + small bills + DCC) and the best (central Tokyo weekday + clean bills + JPY-paid card) on a $500 exchange is roughly Β₯4,500βΒ₯6,000 β over 6 % of the swap.
What this means for your trip
- β Always check the live mid-market rate before walking up to a counter.
- β Bring clean, post-2009 bills in $20+ denominations.
- β Avoid weekend / late-night airport counters when possible; use a 7-Eleven Seven Bank ATM instead.
- β Decline DCC at every terminal β choose JPY.
- β Ask about minimums and rounding before handing over cash.
- β οΈ Don't trust "0 % commission" signs as the full story.
- β οΈ Don't exchange small amounts (<Β₯3,000) at counters; use ATM or accept the convenience cost.
Frequently asked questions
Are these fees illegal?
No β Japan's regulators allow a wide range of pricing tactics as long as they're disclosed in the rate or in posted notices. "Disclosed" can be tiny print on a placard 2 meters from the register, which doesn't help most travelers in practice.
Which Japanese exchange chains are the most transparent?
World Currency Shop publishes its rate online with the mid-market markup visible; Wise (digital) shows every fee in the app before each transaction. Most physical chains (Travelex, Dollar Ranger, Daikoku) are within industry norms but don't break out the spread separately.
What if I'm charged a fee that wasn't disclosed?
Ask for a manager and request the official price list. If the fee was applied without disclosure, most shops will refund or adjust. For airport counters, the airport's tourist information desk can mediate.
Do online exchange platforms have these issues?
Most reputable online platforms (Wise, OFX, XE Money) charge explicit, disclosed fees and avoid the spread markup. The trade-off is that you typically can't get cash on the spot β you get a transfer or a card.
How much does the airport counter actually cost vs the worst
mistake combo? On a $500 exchange:
- Best central-Tokyo shop: cost about Β₯0βΒ₯500
- 7-Eleven ATM with no-FX-fee card: cost about Β₯350βΒ₯600
- Average central-Tokyo shop: cost about Β₯1,000βΒ₯1,500
- Airport counter: cost about Β₯2,000βΒ₯3,500
- Worst combination (airport + weekend + small bills + DCC): cost about Β₯4,500βΒ₯6,000
A factor of 10x between best and worst on the same physical amount of money.
Can I dispute a Japanese exchange shop's rate after the fact?
Practically, no. Japanese consumer protection agencies handle egregious fraud cases, but a "wide spread" or "small-bill penalty" that was technically disclosed in fine print is not actionable. Better to walk away before transacting.
What's the single biggest watch-out for a first-time visitor?
Decline Dynamic Currency Conversion at every card terminal β this single rule saves more money than all other tactics combined, especially for visitors who use cards heavily during their trip.
Open it live in Yen Finder
Yen Finder shows the live mid-market rate alongside every shop's current rate, with a colored badge indicating spread size. Green badges mean the shop is within 0.5 % of mid-market; red means 2 %+ off β that's the spread you'd be paying. Open the app before any exchange and the math is settled.
