Scam Calls and Fraud in Japan: Phrases to Refuse and Report

Phone and message scams in Japan take several familiar forms: callers pretending to be officials or companies, the it's me call claiming to be a relative, and messages about unpaid fees or missed deliveries with a link. Newcomers can be targeted because they may not be sure what a real office would say. This guide describes common patterns in general terms, gives you phrases to refuse and hang up, and explains where to consult. If you are in immediate danger or a crime is happening, call the police emergency number.

Real offices do not ask you to pay or share card details on an unexpected call

Ending the call politely is always acceptable

Verify by calling the official number yourself, never a number the caller gives

Consult quickly if you have already paid or shared information

Common patterns

Scams change their details often, but the underlying patterns are consistent: urgency, authority and a request for money or information. Recognising the pattern matters more than memorising any single script.

What scammers tend to say

Hearing the typical lines in Japanese helps you recognise them quickly. Official-sounding introductions, talk of refunds or unpaid fees, and pressure to act today are all warning signs.

A real office rarely asks you to go to a machine or pay immediately during an unexpected call.

JapaneseRomajiMeaning
市役所の者ですが。Shiyakusho no mono desu ga.I am calling from the city office.
還付金があります。Kanpukin ga arimasu.You are owed a refund.
未払いの料金があります。Miharai no ryōkin ga arimasu.You have an unpaid fee.
今日中に手続きしないと大変なことになります。Kyōjū ni tetsuzuki shinai to taihen na koto ni narimasu.If you do not complete it today, there will be serious trouble.
俺だよ、俺。Ore da yo, ore.It's me, it's me.

Refusing and ending the call

You do not need to argue or explain. A short, polite refusal followed by ending the call is enough, and it is perfectly acceptable in Japanese.

Choose one refusal phrase and practise it until it comes out automatically.

JapaneseRomajiMeaning
結構です。Kekkō desu.No, thank you.
今、忙しいので失礼します。Ima isogashii node shitsurei shimasu.I am busy right now. Goodbye.
こちらからかけ直します。Kochira kara kakenaoshimasu.I will call back myself.
個人情報は電話では教えられません。Kojin jōhō wa denwa de wa oshieraremasen.I cannot give personal information over the phone.
お名前と所属を教えてください。O-namae to shozoku o oshiete kudasai.Please tell me your name and department.

Checking whether a contact is real

If a call or message might be genuine, end it and contact the organisation through a number or website you find yourself. Never use a number or link supplied by the caller.

When you call the real office, describe the contact briefly and ask whether it came from them.

JapaneseRomajiMeaning
そちらから電話がありましたか。Sochira kara denwa ga arimashita ka.Did someone from your office call me?
このようなメッセージが届いたのですが。Kono yō na messēji ga todoita no desu ga.I received a message like this.
この電話番号は御社のものですか。Kono denwa bangō wa onsha no mono desu ka.Is this phone number yours?
リンクは開いていません。Rinku wa hiraite imasen.I have not opened the link.

Where to consult and report

If something feels wrong, consult early. The police consultation line, #9110, gives advice on non-emergency matters such as suspicious calls. The consumer hotline, 188, can advise on suspicious billing or contracts. In an emergency, call 110.

If you have already paid or shared card details, contact your bank or card company first to stop further losses, then consult the police.

JapaneseRomajiMeaning
詐欺の電話がありました。Sagi no denwa ga arimashita.I received a scam call.
お金を振り込んでしまいました。O-kane o furikonde shimaimashita.I have already transferred money.
カードの番号を教えてしまいました。Kādo no bangō o oshiete shimaimashita.I gave them my card number.
カードを止めてください。Kādo o tomete kudasai.Please stop my card.

Protecting yourself day to day

Most scams are avoided by habits rather than knowledge. Treat unexpected requests for money or information with suspicion, and give yourself permission to end any call.

Explaining what happened is the other half of the skill. Unihongo's Report a Lost Wallet mission lets you practise describing an incident at a police counter with an AI Sensei, and the corrections in the session report help you make the explanation clearer.

  • Do not tap links in unexpected messages about payments or parcels.
  • Never share card numbers or passwords on an unexpected call.
  • Verify through official numbers you look up yourself.
  • Talk to someone you trust before sending money under pressure.
  • Keep the consultation numbers saved in your phone.
Key points

A practical way to improve

Practise the three refusal phrases below until you can say them without thinking, then say them aloud in a firm but calm voice. The Report a Lost Wallet roleplay mission in Unihongo is good practice for explaining what happened at a police counter.

  1. 1

    Choose one clear goal

    Focus each session on a situation or skill you can actually use.

  2. 2

    Practice actively

    Say complete answers aloud instead of only reading or recognizing Japanese.

  3. 3

    Review and repeat

    Keep useful corrections and revisit the same skill until it feels natural.

FAQ

Frequently asked questions

What is the police consultation number?

The police consultation line is #9110. It is for consultations rather than emergencies, such as advice on suspicious calls. For emergencies or crimes in progress, call 110.

Where can I ask about suspicious sales or billing?

The consumer hotline at 188 connects you to a consumer affairs centre that can advise on suspicious contracts, billing and sales. Availability of other languages varies.

Is it rude to hang up?

Not when the call is suspicious. Saying kekkō desu, shitsurei shimasu and ending the call is a completely normal response to an unwanted call.

What if I already paid money?

Contact your bank or card company immediately to stop further payments, then consult the police. Acting quickly gives the best chance of limiting the damage.
