If you have ever tried to send money overseas from Japan, you have probably been asked to enter a remittance purpose code. It can feel like an unexpected hurdle — especially when your Japanese is limited and the dropdown list looks confusing. The good news is that the concept is straightforward once you understand what it is and why it is required. This guide walks you through everything you need to know about remittance purpose codes in Japan so you can send money home with confidence.
What Are Remittance Purpose Codes?
A remittance purpose code is a short classification code that tells the bank or transfer service why you are sending money abroad. It is not unique to Japan — financial institutions around the world use similar systems as part of international regulations designed to prevent money laundering and illegal financial flows.
In Japan, banks and licensed money transfer services are required by law to collect this information whenever you send money internationally. The code you select gets reported to the relevant financial authorities as part of standard compliance procedures. It is a legal requirement, not optional.
Why Do Japanese Banks and Transfer Services Ask for This?
Japan's financial regulations — guided by the Act on Prevention of Transfer of Criminal Proceeds and international standards set by organisations like the Financial Action Task Force (FATF) — require that all international money transfers include a stated purpose. This helps authorities:
- Monitor for suspicious or unusual transactions
- Prevent money laundering and fraud
- Ensure funds are not linked to illegal activities
- Keep Japan's financial system trustworthy and stable
As a foreign resident in Japan sending money to your family, you have absolutely nothing to worry about. This is a routine part of the process — every international sender goes through it.
Common Remittance Purpose Codes You Will See
The exact list of codes varies slightly depending on whether you are using a bank or a specialist transfer service, but the most common categories you are likely to encounter include:
| Purpose | Typical Use Case |
|---|---|
| Family support / Living expenses | Sending money to parents, a spouse, or other family members for daily living costs |
| Education fees | Paying tuition or school fees for a family member studying abroad or in your home country |
| Own account transfer | Transferring money to your own bank account in another country |
| Salary / Income transfer | Sending your earned salary or wages to an account you own overseas |
| Savings | Moving funds to a savings account you hold in your home country |
| Loan repayment | Repaying a loan or debt held in another country |
| Payment for goods / services | Paying a business or individual for a product or service |
| Investment | Transferring funds for investment purposes overseas |
Most foreign residents in Japan who are sending money home will simply choose "Family support" or "Living expenses". This is the correct and honest choice if you are helping parents, a spouse, siblings, or children cover their everyday costs.
How to Choose the Right Purpose Code
The most important rule is simple: always select the code that accurately reflects your real reason for sending money. Do not guess or choose a random option just to get through the form. Providing false information is a serious matter under Japanese law.
Here is a quick guide to help you decide:
- Helping family with rent, food, medical bills, or daily costs? → Choose "Family support" or "Living expenses"
- Paying your child's school or university fees? → Choose "Education fees"
- Moving your own savings or salary to your personal account abroad? → Choose "Own account transfer" or "Salary transfer"
- Paying back a loan you took out in your home country? → Choose "Loan repayment"
If you are genuinely unsure which code applies to your situation, contact the bank or service's customer support before submitting. Most major transfer services have English-language support available.
Where You Will Enter the Purpose Code
The process differs slightly depending on which service you use:
Specialist Transfer Services (Wise, Remitly, etc.)
Services like Wise and Remitly include the purpose code selection as a standard step within their app or website during the transfer setup. It usually appears as a dropdown menu after you enter the recipient's details. The options are clearly labelled in English, making it easy to choose the right one.
Japanese Bank Wire Transfers
If you are sending from a Japanese megabank such as MUFG, SMBC, or Mizuho, the purpose code may be required either online or at the branch counter. At a branch, a member of staff will ask you to fill in a transfer form that includes a purpose field. The form may be in Japanese, so it is worth preparing your answer in advance — for most residents, simply writing "family support" or "living expenses" is sufficient to clarify.
Does the Purpose Code Affect the Transfer?
For the vast majority of everyday transfers — sending money home to family — choosing the correct code will not slow down your transfer or create any complications. However, in some cases, if you select a purpose that requires additional documentation (such as a large investment transfer or a business payment), the bank may ask you to provide supporting paperwork before processing the transaction.
As a general rule, routine family support transfers are processed without any extra steps beyond selecting the correct code.
A Note on Choosing the Right Transfer Service
Beyond purpose codes, it is worth making sure you are using a service that gives you good value. Bank wire transfers from Japanese megabanks tend to be the most expensive option because of high flat fees and a poor exchange-rate margin. Specialist services like Wise — which uses the real mid-market exchange rate with a transparent fee — or Remitly — which often offers promotional rates for first-time users and supports cash pickup in many countries — can save you a meaningful amount on each transfer.
The true cost of any transfer is the transfer fee plus the exchange-rate margin, not just the advertised fee. Always check the live quote in the official app before confirming. Fees and rates change regularly, so check each service's official website for the most current information.
To send money from Japan you will generally need your residence card (zairyu card) and a Japanese bank account or debit card. Keep these handy before you start.
Summary: Remittance Purpose Codes Made Simple
Remittance purpose codes in Japan are a standard legal requirement — not something to be anxious about. They exist to keep the financial system safe and transparent for everyone. Here is a quick recap:
- Always choose the code that honestly reflects your reason for sending money
- For most foreign residents sending money to family, "Family support" or "Living expenses" is the right choice
- Do not guess — if you are unsure, contact customer support before submitting
- The code does not affect your transfer speed or cost for routine family remittances
- Compare services on the total cost (fee + exchange-rate margin) and confirm the latest rates on official sites before sending
Sending money home is one of the most important financial tasks you handle as a foreign resident in Japan. Once you understand what purpose codes mean and how to fill them in correctly, the whole process becomes much less stressful. You are doing the right thing — take it one step at a time, and you will have your money on its way in no time.
