Avoiding Scams and Phishing in Japan: Fake Texts, Calls and Delivery Cons
Updated: 2026-09-04
Quick answer
Most scams that reach new residents in Japan arrive quietly, as a text message or a phone call that looks routine. The usual ones are fake parcel-delivery notices, messages pretending to be your bank or a payment app, and phone calls that invent an urgent problem. None of them are clever once you know the shape they take.
The single habit that protects you: never tap a link or follow instructions from an unexpected message, and never move money or read out a code because someone on the phone told you to. Open the company's real app or website yourself instead. That one pause defeats almost everything below.
Fake delivery-notice texts
A very common message claims a parcel could not be delivered and asks you to tap a link to reschedule delivery or confirm your address. It may borrow the name of the postal service or a courier, and the link leads to a copycat page that harvests your login or card details, or asks you to install an app.
Real couriers in Japan leave a paper slip in your mailbox and let you arrange redelivery through their own official app or the number printed on that slip. If a delivery text contains a link, treat the link itself as the warning sign. Look up the courier's redelivery page yourself rather than tapping through.
Spoofed bank and payment messages
Another wave imitates banks, card issuers, tax offices and payment apps. The message says your account is locked, a payment failed, or a refund is waiting, and it pushes you toward a link to verify. The page can look identical to the genuine one, right down to the logo.
Banks and payment services in Japan do not ask you to confirm passwords, card numbers or one-time codes through a link in a text or email. When in doubt, close the message and open the app you already have, or call the number on the back of your card. A genuine issue will still be there when you log in the normal way.
Phone-call cons
Some scams come by voice. A caller may claim to be from a delivery firm, a government office, a card company, or even a relative in trouble, and the goal is to create urgency so you act before you think. Refund scams that steer people to an ATM to receive money back are common and specifically target residents who are unsure of the system.
No real institution will ask you to withdraw cash, buy prepaid gift cards, or read out codes over the phone. If a call makes you feel rushed or frightened, that feeling is itself the clue. Hang up, take a breath, and call the organisation back on a number you looked up independently.
How to spot the pattern
The red flags repeat: an unexpected message with a link, pressure to act immediately, a request for a password, card number or verification code, and an odd sender address or slightly wrong web address. Stilted or machine-translated Japanese, or a link that does not match the company's real domain, are further hints.
You do not need to identify every scam on sight. You only need one rule you never break: verify through a channel you already trust — the official app, a bookmarked site, or a printed customer-service number — before you tap, pay, or reveal anything.
Where to get help and report it
If you have lost money or shared details, contact your bank or card company at once to freeze or watch the account. For advice in Japan you can call the Consumer Hotline on 188, and for non-emergency police guidance the consultation line #9110. In an emergency, 110 reaches the police directly.
It helps to keep the evidence: a screenshot of the message, the sender's number or address, and any link (without tapping it). Reporting phishing also protects others, and many banks and services have a dedicated page for forwarding suspicious messages.
Your number is part of staying safe
Almost all of these scams arrive as an SMS or a call to your Japanese phone number, so understanding how that number is used — and misused — is simply part of living here calmly. Getting your own number and data early gives you a stable line for banking, deliveries and daily life, instead of relying on borrowed or throwaway connections.
The mobile contract needs your residence card, which is issued after you land, so you sign up once you arrive rather than before. With an eSIM the line can activate the same day in about fifteen minutes, with no store visit. A real carrier line with proper support also means there is someone to turn to when something looks wrong, which beats a disposable number every time.
