Yes, you can deposit yen, but your bank will convert it to dollars and charge you for the conversion
Most US banks accept foreign currency deposits, including yen. However, the process is not the same as depositing a check or cash in dollars. Your bank will convert the yen to US dollars at their exchange rate, deduct a conversion fee, and credit your account with the remaining amount in dollars. The entire transaction typically takes 5 to 10 business days, and you will lose money on both the exchange rate and the fee.
The exact process and fees depend on your bank and the amount you are depositing. Some banks handle foreign currency deposits at the branch level; others send them to a correspondent bank that specializes in currency conversion. Either way, you have no control over the exchange rate they use, and it will be worse than the mid-market rate you see online.
Key Takeaways
- Your US bank will convert yen to dollars automatically, but you will pay both a conversion fee and an unfavorable exchange rate.
- Physical yen cash and yen checks are handled differently—cash deposits are faster but checks take longer and may be rejected if the bank cannot verify them.
- For large amounts, a wire transfer from a Japanese bank account costs less than converting physical currency at a US bank.
- Some banks charge flat fees for foreign currency deposits; others charge a percentage of the amount converted, so calling ahead to ask your bank's specific fee is worth the time.
How banks handle physical yen cash deposits
If you have yen in cash, you can take it to your bank branch and ask to deposit it. The teller will count the bills, note the amount, and send them to a currency exchange service or correspondent bank. That service converts the yen to dollars at their rate, deducts their fee, and your bank credits your account with the result.
Physical cash deposits usually take 5 to 10 business days to clear. During that time, the exchange rate can move against you—if the yen weakens relative to the dollar while your deposit is in transit, you will receive fewer dollars than you would have on the day you deposited it. Your bank typically locks in the rate on the day the currency exchange service receives the cash, not the day you handed it to the teller.
Some banks will not accept foreign currency cash at all, or will only accept it at certain branches. Call your bank before you go to the branch with yen in hand.
Yen checks and wire transfers from Japan
Depositing a yen check is slower and riskier than depositing cash. Your bank will send the check to a correspondent bank in Japan for collection, a process that can take 2 to 4 weeks. If the check cannot be verified or if there is a problem with the account it is drawn on, the check will be returned unpaid and your bank may charge you a return fee of $15 to $30.
A wire transfer from a Japanese bank account is faster and more reliable. The money arrives in your US account in 1 to 3 business days, and there is no risk of the transfer being returned. However, wire transfers carry their own fees—typically $15 to $50 on the US side, plus whatever your Japanese bank charges on their end. For amounts under $500, a wire transfer may cost more than a currency exchange fee; for amounts over $2,000, a wire is usually cheaper.
Exchange rates and fees: what you actually pay
Your bank does not use the mid-market exchange rate—the rate you see when you search "USD to JPY" online. Instead, they use their own rate, which is typically 1 to 3 percent worse than mid-market. On top of that, they charge a conversion fee, which ranges from a flat $15 to $50 or a percentage of the amount converted (usually 1 to 2 percent).
Example: You deposit ¥100,000 in cash. The mid-market rate is 1 USD = 150 JPY, so mid-market value is $667. Your bank's rate might be 1 USD = 154 JPY (worse for you), giving you $649. Then they deduct a $25 conversion fee, leaving you with $624. You lost $43, or about 6.4 percent of the value, to the rate spread and fee combined.
Before you deposit, call your bank and ask: What is your exchange rate for yen deposits? Do you charge a flat fee or a percentage? Is there a minimum or maximum amount? Some banks offer better rates for larger deposits, and some waive fees for customers with premium accounts.
When to use a currency exchange service instead
If your bank's fees are high or their rate is particularly bad, you can convert yen to dollars at an independent currency exchange service before depositing the dollars. Services like OFX, Wise, or local currency exchanges often offer rates closer to mid-market than banks do, though they also charge fees.
The trade-off is time and convenience. You have to physically go to the exchange service (or use an online service and wait for a wire transfer), convert the yen, and then deposit the dollars. For small amounts, this is not worth the extra step. For amounts over $5,000, it may save you money to compare your bank's all-in cost against what an exchange service would charge.
Be aware that some currency exchange services are not regulated the same way banks are. Check that the service is registered with FinCEN (the Financial Crimes Enforcement Network) before you send them money.
Timing and what to expect after you deposit
After you hand over yen cash or a check at your bank branch, the teller will give you a receipt showing the amount of yen deposited. Your account will not be credited immediately. Instead, the bank will send the currency to a conversion service, which converts it and sends the dollars back to your bank. This takes 5 to 10 business days for cash and 2 to 4 weeks for checks.
During this time, your bank may place a hold on the deposit, meaning the money will not be available for withdrawal even after it hits your account. Holds on foreign currency deposits typically last 5 to 10 business days after the conversion is complete. If you need the money urgently, ask your bank whether they will release funds before the hold expires—some will for customers with good account history.
Once the hold is lifted, the dollars are yours to use. The conversion is final; you cannot reverse it or ask for a better rate retroactively.
Frequently Asked Questions
What if my bank says they do not accept yen deposits?
Some smaller banks and credit unions do not handle foreign currency deposits at all. If yours does not, you can convert yen to dollars at an independent currency exchange service first, then deposit the dollars. Alternatively, you can open an account at a larger bank that accepts foreign currency, though this is only practical if you plan to make regular deposits.
Do I have to report yen deposits to the IRS?
No. Deposits of your own money are not taxable income. If the yen came from work, investment income, or another source that would be taxable, you report the income itself, not the deposit. Your bank will not report the deposit to the IRS unless the amount is over $10,000 in a single day, in which case they file a Currency Transaction Report—this is routine and does not mean you are under investigation.
Can I deposit yen into a savings account or only checking?
Most banks allow foreign currency deposits into either account type. However, some banks only accept foreign currency at certain branches or only for certain account types. Call your bank and ask before you go to the branch.
What if the yen weakens while my deposit is being processed?
You will receive fewer dollars. Your bank locks in the exchange rate on the day the currency exchange service receives the yen, not the day you deposited it. If the yen weakens between those two dates, you absorb the loss. This is why large deposits are sometimes worth converting through an independent service or via wire transfer—you can lock in a rate immediately instead of waiting for the bank's process.
Is there a limit to how much yen I can deposit?
Most banks do not have a limit on foreign currency deposits, but some require advance notice for amounts over $10,000. Call your bank to ask. Amounts over $10,000 in a single day trigger a Currency Transaction Report, which is standard and not a problem as long as the money is legitimate.
