No, you wouldn't be dumb, but you should do the math first, because a foreign transaction fee can quietly cancel out a bigger bonus if your Japan restaurant spending is high enough. A fee on foreign purchases is a percentage of each charge, so it grows with every dinner, while a sign-up bonus is a one-time payout. The smart move is to put both numbers side by side: what the extra bonus is worth, and what the fee will cost on the total you expect to spend abroad.
Key Takeaways
- A foreign transaction fee is a percentage of every purchase, so the more you spend in Japan, the more it costs.
- A one-time bonus can outweigh the fee on modest spending, but heavy restaurant spending can flip the answer.
- Compare the extra bonus to your expected fee total, or carry a second card with no foreign transaction fee for the dining.
What does a foreign transaction fee actually cost you?
A foreign transaction fee is a charge added to purchases made outside the US or processed by a foreign bank. It's a percentage of each purchase, and it shows up on your statement as a separate line. Compare current business card offers.
Because it's a percentage, the math is simple. Say the fee is 3% and you spend $4,000 on restaurants in Japan. The fee would be $120. Spend $10,000 and it would be $300.
Restaurants are a place where this adds up fast. Meals are frequent, they're often paid for the whole table, and business dining can mean client dinners that run high. Small charges that seem harmless each time can build into a real number by the end of the trip.

Learn MoreHow much is the bigger bonus really worth?
A sign-up bonus is a one-time reward for spending a set amount in the first few months. It's real value, though it only counts if you can hit the minimum spend through normal business costs. In the CFPB's data, the average rewards bonus earned on general-purpose rewards cards was $311 per account in 2024.[1]
Bonuses also make up a meaningful slice of what people earn. Sign-up bonuses accounted for nearly one in 10 dollars of credit-card rewards earned overall.[2]
So a bonus can be a big part of a card's value. But a bigger bonus only wins if it's bigger by more than the fees you'd pay. What matters is the gap between the two cards' bonuses, not the bonus on its own.
If one card's bonus is worth $300 more than the other's, that $300 is what you're weighing against your fee total. Compare the difference, not each bonus alone.
A quick percentage calculation tells you how much a foreign fee could cost on your expected spending.
Would I be dumb to take the fee card? Run this math
Here's a simple way to decide. Take your expected Japan restaurant spending, multiply by the fee percentage, and compare that with the extra bonus the fee card gives you.
Example: the fee card's bonus is worth $400 more than the no-fee option, and the fee is 3%. If you'll spend $5,000 on dining in Japan, the fee is $150. You'd come out about $250 ahead. If you'll spend $15,000, the fee is $450, and you'd be $50 behind.
The break-even point here is about $13,300 in foreign spending, since $400 divided by 3% is that amount. Below it, the fee card wins on paper. Above it, the no-fee card does.
Don't forget the rewards on the spending itself. If the two cards earn different rates on dining, add that difference in too. Rewards earned averaged 1.6% of purchase volume on general-purpose rewards cards in the CFPB's most recent data,[3] so a fee of around 3% can be bigger than what you'd earn back on the same charge.
- Estimate your total Japan restaurant spending.
- Multiply it by the foreign transaction fee percentage.
- Subtract that from the extra bonus the fee card offers.
- Add or subtract any difference in rewards on dining.
- Factor in annual fee differences for the first year.

Can you get the bonus and still avoid the fees?
Often, yes. Nothing says you have to use the same card for everything. You could open the business card with the bigger bonus, meet the minimum spend with domestic costs like software, supplies, or advertising, and then pay for Japan meals with a different card that has no foreign transaction fee.
This works best if your normal business spending is enough to hit the bonus minimum without the Japan trip. If the trip is the only way you'd reach it, the fee card starts to look more appealing, since those charges earn you the bonus too.
Keep one more thing in mind: the fee only applies to foreign purchases. If you'll mostly pay in yen, you'll pay it. Some merchants offer to charge in US dollars instead, but that conversion often comes with a worse exchange rate, so it's usually better to pay in yen.
Many travelers bring a second card anyway, in case one is declined or lost. Making it a no-foreign-fee card gives you a backup and a cheaper option for dining.
When does the fee card make sense?
The fee card is a reasonable choice when your foreign spending is modest, the bonus gap is large, and you'll comfortably meet the minimum spend. It also makes sense if the card has other benefits your business uses year-round, since you'll be using it for more than one trip.
It's a harder sell if you'll spend heavily abroad, travel to Japan often, or only want the card for one purpose. In those cases the fees keep recurring while the bonus happens once.
And whichever card you pick, pay the balance in full. Interest charges can wipe out any rewards faster than a foreign fee can. These are generally recommended for good to excellent credit, so check your own credit situation before you apply.

The Bottom Line
You're not dumb to choose a business card with a foreign transaction fee, as long as the bigger bonus beats the fees you'd pay on your Japan dining. For modest spending, it often does. For heavy restaurant spending, the fees can take it all back.
The safest plan is to do the math, and if the numbers are close, split the job: use the bonus card for domestic business costs and a no-foreign-fee card for meals in Japan. Compare current offers to find the combination that fits your spending.
