The cheapest way to send money home from Japan is almost never your bank — licensed remittance apps move the same yen for a fraction of the cost, with the real difference hiding in the exchange-rate margin rather than the advertised fee. Setup takes a residence card and My Number once, transfers arrive in minutes to days, and the golden rule is to compare the amount received, not the fee charged. Informal hand-carry networks undercut nobody once confiscation and legal risk are priced in.

Where the cost actually hides
Every transfer has two prices: the fee printed in the app and the exchange-rate margin buried in the conversion. Specialist providers charge a visible few hundred yen and shave 0.5–1% on the rate; banks charge thousands in fees and take a wider margin. This is why the only honest comparison is done backwards — start from the same ¥100,000, and ask each service how much lands on the other side. The winner changes by corridor and by week, so people who remit monthly re-check a couple of apps each time rather than staying loyal.
Setting up the pipe
The one-time setup needs your Japanese bank account as the funding anchor, your residence card, and your My Number — providers must collect it by law, so treat the request as a good sign, not a red flag. Most licensed apps cap single transfers around ¥1,000,000, deliver to bank accounts, cash-pickup counters, or mobile wallets, and land in minutes to two days depending on the corridor. After registration, a monthly remittance is a two-minute phone task.
The channel to refuse
In every migrant community there’s an informal offer: someone collects yen here and pays out at home at a “better rate.” Refuse it. The unlicensed channel is illegal at both ends, has no recourse when the money disappears, and the collected accounts on the Japan side regularly surface in money-laundering prosecutions — the same trap as lending your bank account. The licensed route costs perhaps 1% more and comes with receipts — which themselves have value: a steady, documented record of supporting family is evidence that helps rather than haunts you at tax and visa time.
Common mistakes & warnings
- Never use informal money carriers or "someone in the community who sends cheap" — these unlicensed channels are illegal on both ends, offer zero recourse when money vanishes, and using them can implicate you in someone else's money-laundering case.
- The advertised "zero fee" is usually recovered in the exchange rate — a 2% FX margin on a ¥100,000 transfer quietly costs ¥2,000. Always compare the final amount your family receives from the same yen.
- Keep transfer receipts — a consistent remittance record supports dependents' visa applications, and unexplained large flows in either direction attract compliance reviews on your Japanese account.
Frequently asked questions
What do I need before my first transfer?
A Japanese bank account, your residence card, and your My Number — remittance providers are legally required to collect it. Registration is a one-time step of a day or two; after that, transfers are minutes of phone work.
Why not just use my bank?
A megabank wire costs ¥3,000–7,500 in named fees, takes days, often requires counter visits, and applies a wider exchange margin on top. Licensed apps move the same money for a fraction of that — banks make sense mainly for very large sums above app limits.
Is there tax on money I send home?
Japan doesn't tax outbound remittances of your own earned income — the money was already taxed as salary. Two caveats — large transfers may prompt your bank to ask the purpose, which is routine, and the recipient country's gift or income rules are a separate question worth checking locally.
