Getting yen feels like a chore you just get done at the airport. That reflex quietly costs you money — the airport counter is convenient precisely because it can afford the worst rate. Mio doesn't care about convenience. Here's the math on the cheapest way to get Japanese yen.
Every method has two costs stacked on top of each other. First, the FX markup — how far the rate you're given sits from the real mid-market ("interbank") rate. Second, the fixed fees — an ATM fee, a "foreign transaction" fee, or a flat commission. A counter can advertise "0% commission" and still lose you money through a wide rate spread. Add both to see the truth.
1. Airport / hotel cash exchange counters. The most convenient, and usually the worst rate — the markup is wide because you're paying for being right there at arrivals. Fine for a small emergency float; avoid it for large amounts.
2. ATM withdrawal with your home card at a 7-Eleven (Seven Bank) or Japan Post Bank ATM. These reliably accept foreign debit and credit cards and hand you a near-interbank rate. The catch is your home bank: it may add a foreign-ATM fee plus an FX fee (roughly ¥110–220 ATM fee + ~1–3% card FX, illustrative — check your own card).
3. A travel money / multicurrency card (Wise, Revolut and similar). You load yen at close to the mid-market rate in advance, then withdraw at a 7-Eleven ATM. If it lets you dodge your home bank's FX margin, this is usually the cheapest all-in option.
| Method | Rate quality | Typical fees | Best for |
|---|---|---|---|
| Airport / hotel counter | Worst (wide markup) | Baked into the rate | Tiny emergency float only |
| 7-Eleven / Japan Post ATM (home card) | Near mid-market | ~¥110–220 + ~1–3% home-bank FX | Most travellers, no prep |
| Travel money card + 7-Eleven ATM | Near mid-market | Low load fee; small ATM fee | Cheapest all-in, a little prep |
Figures are illustrative and change often — compare your own card's fees before you travel.
| Method | Rough all-in cost of ¥50,000 |
|---|---|
| Airport counter (~5–8% wide markup) | You effectively pay ~¥52,500–54,000 worth |
| 7-Eleven ATM, home card (~2% FX + ¥220) | ≈ ~¥51,200 worth |
| Travel card + 7-Eleven ATM (~0.5% + small ATM fee) | ≈ ~¥50,500 worth |
Same ¥50,000 in your hand, but the airport counter can quietly cost ¥2,000–3,500 more than a travel card for one withdrawal. Do that a few times on a trip and the gap is a nice meal.
The ATM fee is a flat cost, so it hurts most on small withdrawals. Pulling ¥10,000 five times pays the fixed fee five times; pulling ¥50,000 once pays it once. Withdraw a larger amount less often (within what you're comfortable carrying) and the per-yen cost drops. Just keep an eye on your card's per-withdrawal limit.
Don't exchange large cash at the airport. Use a fee-light debit or travel money card at a 7-Eleven (Seven Bank) or Japan Post Bank ATM, and withdraw larger amounts less often to spread the fixed ATM fee. Japan is still cash-heavy in smaller shops, temples and rural areas, so always carry some yen — but get it the calculated way, not the convenient one. Sorting your data and connectivity → before you land saves the same kind of quiet markup.
