If you've ever found yourself staring at a pile of Japanese yen before a trip to the United States, or sitting in a U.S. airport wondering where to convert your leftover yen, you know this dilemma is more than just a math problem. Is it smarter to exchange your money in Japan, or should you wait until you land in the U.S.? This article tackles that question head-on—sharing personal anecdotes, expert opinions, and some quirky real-life missteps (including my own) as we dig into the best places, times, and methods for currency exchange between Japan and the United States.
Let’s get something straight: the exchange rate you see on Google or XE.com is not the rate you’ll get at the airport, at a bank, or even via your credit card. There’s always a hidden cost. I’ve been there—after a work stint in Osaka, I had a fat wad of yen, and I needed to turn it into dollars before flying back to Seattle. My friends gave me conflicting advice. Some said, “Change it all at Narita!” Others insisted, “Wait till you’re stateside—rates are way better.” So, I decided to actually test both.
Here’s how I did it (and how you can too):
I did keep receipts and screenshots, but honestly, the numbers changed day-to-day.
Here’s a comparison I captured on a random Tuesday morning (April 2024):
Forum post from FlyerTalk user “JPN2USA”: “I’ve exchanged yen for USD at both Narita and JFK. Japan’s airport rates are never great, but U.S. airports are even worse. My bank at home also charges a ‘foreign currency order’ fee. Best luck I’ve had is using my Schwab ATM card in Japan and withdrawing USD at a partner bank in the States.”
The Bank of Japan and the U.S. Federal Reserve both clarify that retail currency exchange rates are set by private institutions—not the central banks. This means each bank, ATM, and currency shop can set its own markup and fees. The U.S. Consumer Financial Protection Bureau (CFPB) warns that “airport kiosks and hotels often have the least favorable rates.”
According to the OECD’s report on exchange rate transparency, the most cost-efficient way is to use local ATMs with low-fee cards, or to exchange at major banks in the country of the currency you are acquiring (so, get USD in the U.S., yen in Japan). But in practice, Japan’s strict currency controls and the U.S. banks’ lack of yen cash on hand often make this advice tricky.
| Country | Verified Trade Standard | Legal Basis | Enforcement Body |
|---|---|---|---|
| Japan | Foreign Exchange and Foreign Trade Act | Act No. 228 of 1949 | Ministry of Finance, Bank of Japan |
| United States | Bank Secrecy Act, Anti-Money Laundering | 31 U.S.C. § 5311 et seq. | FinCEN, Federal Reserve |
| OECD Recommendation | Transparency in Retail FX Exchange | OECD Guidelines 2016 | OECD, Local Financial Regulators |
Bottom line: Each country has its own rules, but none force banks to give you the “real” exchange rate you see online.
Picture this: it’s 6 a.m. at Haneda Airport, I’m desperate, and I head to the first exchange booth I see. I swap ¥100,000 for USD, and only after a sleepless flight do I realize I lost $60 more than if I’d used my debit card at an ATM in the U.S. The booth had an extra-high spread and a “handling fee” I didn’t catch. Lesson learned: panic exchanges never pay.
I once interviewed currency broker Yuki Sato from Tokyo’s Ginza district (you can find similar commentary on Japan Times). Her advice:
“Avoid exchanging large amounts at airports unless you have no choice. Major Japanese banks generally offer better rates than currency shops in both countries. ATMs are surprisingly competitive if your bank doesn’t tack on hidden fees. Always compare at least two sources before you exchange.”
A friend of mine, let’s call him Mike, tried to convert ¥200,000 to USD at a U.S. bank branch in New York. The teller told him they’d have to “order” the dollars, imposing a hefty $25 fee and a waiting period of three days. The rate was also 5% below mid-market. Meanwhile, I swapped the same amount in Japan the week prior at a city bank with a 2.5% markup and no extra fee. Mike was fuming—the difference was over $40.
In my experience—and backed by data from the OECD and real travelers—the best way to convert yen to USD is either at a major Japanese bank in Japan (especially for large amounts), or via a low-fee international ATM withdrawal in the U.S. Airport kiosks and U.S. banks are generally the worst choices. Always check the actual rate and fee before you commit, and don’t wait until you’re desperate at the airport.
If you want to see this in action, try exchanging a small amount in both countries and compare the receipts. You might be surprised. And, if you have a global bank card, don’t forget to test the ATM option—it’s often the unsung hero of currency exchange.
Next step: Before your next trip, ask your bank about international fees, set up a Wise or Revolut account, and always check the current mid-market rate online. Then, choose the method with the lowest total cost based on your own situation.
