Japan Overseas Remittance Guide: Feeling Overwhelmed by Your First International Transfer?
If you’ve ever tried sending money to or from Japan for the first time, you probably remember that feeling.
The exchange rate looks confusing.
Bank staff mention unfamiliar terms.
And somehow, the money that arrives is less than what you expected.
Whether you’re:
- A student moving to Japan
- On a working holiday visa
- Supporting family back home
- Or working in Japan and sending savings overseas
International transfers can feel unnecessarily complicated.
Today, I’ll walk you through this clearly and calmly — comparing traditional SWIFT bank transfers with Wise, and explaining whether Japan’s My Number card is actually required.
Let’s simplify this.
Why Are Traditional SWIFT Transfers So Expensive?
Most banks around the world use the SWIFT network (Society for Worldwide Interbank Financial Telecommunication).
It’s secure.
It’s global.
But it’s not simple.
When you send money internationally through your bank, the funds rarely go directly from Bank A to Bank B.
Instead, they often pass through:
- Your sending bank
- One or more intermediary (correspondent) banks
- The receiving bank
At each step, fees may be deducted.
And that’s not even the biggest cost.
The Hidden Cost: Exchange Rate Margin
Banks don’t use the real mid-market exchange rate (the rate you see on Google).
They apply their own rate — with a built-in spread.
That spread is profit for the bank.
So even if the transfer fee looks reasonable, you’re often paying more through the exchange rate itself.
For large transfers, this hidden margin becomes significant.
How Wise (Formerly TransferWise) Keeps Fees Low
Wise works differently.
Instead of physically moving money across borders, it matches transactions locally.
Here’s how it works:
If you send $1,000 from Korea to Japan:
- You deposit KRW into Wise’s Korean account.
- Wise pays out JPY from its Japanese account to the recipient.
No cross-border bank chain.
No intermediary banks.
Just internal matching.
That’s why:
- Transfers are faster
- Fees are transparent
- Exchange rates are fair
Most importantly, Wise uses the mid-market rate — the real rate without markup.
They charge a clearly displayed service fee instead of hiding profit in the exchange rate.
That transparency is what changed the game.
Wise vs SWIFT: Side-by-Side Comparison
| Feature | Bank SWIFT Transfer | Wise Transfer |
|---|---|---|
| Exchange Rate | Bank rate (with margin) | Mid-market rate |
| Fee Structure | Sending + intermediary + receiving fees | Transparent service fee |
| Speed | 2–5 business days | Seconds to 2 days |
| Transfer Limits | Generally flexible | Per-transaction limits |
| Best For | Large corporate transfers | Personal transfers |
When Should You Use Each?
From experience and research:
Wise is ideal for:
- Monthly living expenses
- Rent payments
- Tuition transfers
- Small to mid-size regular transfers
SWIFT may be better for:
- Large property purchases
- Business capital transfers
- Situations requiring in-branch consultation
It’s not about which is “better.”
It’s about which fits your purpose.
Do You Need a My Number Card in Japan?
Now let’s talk about Japan’s My Number system.
For U.S. readers unfamiliar with it:
Japan assigns every resident a 12-digit Individual Number (similar in function to a Social Security Number).
Financial institutions must follow strict anti-money laundering laws.
If You Use a Japanese Bank:
Most banks require My Number documentation when:
- Sending money abroad
- Receiving certain international transfers
You’ll typically need:
- My Number Card
OR - A resident certificate showing your My Number
Plus your residence card.
If You Use Wise Japan:
Wise is licensed in Japan as a registered fund transfer service provider.
They must follow KYC (Know Your Customer) regulations.
For account activation, you will usually need:
- My Number documentation
- Residence card
- Identity verification via app
If you just arrived and don’t have the plastic My Number card yet, you can obtain a residence certificate from your local ward office showing your number.
Important:
If you are sending money from the U.S. or Korea into Japan, the recipient’s My Number is NOT required.
The My Number requirement applies to the sender in Japan, not the receiver.
My Final Thoughts
If you’re sending regular payments between Japan and Korea — or Japan and the U.S. — Wise is typically more cost-efficient and transparent.
For very large transfers, compare carefully.
Sometimes traditional banks offer exchange rate benefits for VIP customers.
The key is awareness.
Once you understand where the fees are hiding, you stay in control.
And that’s the real goal.

Once you start thinking about international transfers,
a bigger question naturally follows:
“How do I actually set up my entire financial life in Japan?”
Sending money is just one piece of the puzzle.
Living in Japan means understanding how to:

- Navigate Japan’s cashless payment ecosystem
That’s why I’ve put together a separate guide:

It’s designed especially for newcomers.
Step-by-step explanations,
required documents for foreigners,
