Why Studying Phone Scam Cases Matters
According to National Police Agency confirmed figures, losses from special fraud totaled approximately 45.3 billion yen in 2023 and approximately 71.9 billion yen in 2024. The belief that "I would never fall for a scam" tends to lower your guard rather than protect you. This article covers three major categories - impersonation scams, tax refund fraud, and bogus billing - with representative examples assembled from typical tactics, and the lessons they teach. Understanding these cases builds your ability to recognize the "patterns" behind scams. Please also review basic measures against bank transfer fraud.
Recognized special fraud cases numbered 19,038 in 2023, about 8% more than the 17,570 recorded the previous year. That works out to roughly 52 cases per day - this is not someone else's problem. Victims aged 65 or older accounted for 78.4% of the total in 2023 and 65.4% in 2024. Younger people are targeted as well, so knowing the tactics is the best defense regardless of age.
Impersonation Scam Cases
Case 1: An Emergency Call Pretending to Be a Son
Ms. A, a woman in her 70s, received a call on a weekday morning: "Mom, something terrible has happened." She noticed the voice sounded different from her son's, but the caller explained it away by saying he had a cold. He tearfully claimed he had misused company funds and needed 3 million yen by the end of the day or the police would be called. Shaken, Ms. A also received a call from someone claiming to be her son's supervisor, and she ended up handing over cash at a designated location. The total loss was 3 million yen.
The key feature of this case is how the biggest clue - the different voice - was rationalized away by the "cold" excuse. The credibility was further boosted by a "theatrical" approach involving an accomplice playing the supervisor. Typically the "son," the "supervisor," and the "receiver" (the person who picks up the cash) are played by different individuals under a division of labor.
Case 2: A Call Impersonating a Police Officer
Mr. B, a man in his 80s, received a call from an 03 number: "This is Detective So-and-so from the police. Your bank account is suspected of being used in a crime." He was told his account needed to be frozen and was asked to hand over his cash card. A "detective" who came to his home showed something resembling a police badge (caller ID spoofing combined with impersonation), and Mr. B believed it was real. He handed over his card and PIN, losing approximately 5 million yen.
Police officers will never ask to hold your cash card, nor will they ever ask for your PIN. Tactics impersonating public authorities are often combined with caller ID spoofing, making it dangerous to trust a call based solely on the displayed number. If something feels off, hang up and contact your local police station directly.
Tax Refund Fraud Cases
Case 3: A Fake Refund Notice from City Hall
Ms. C, a woman in her 60s, received a call from someone claiming to be from the city's insurance division: "You have a medical expense refund of 38,000 yen. Today is the deadline, so please complete the procedure at an ATM." Trusting that a call from city hall must be legitimate, she went to a convenience store ATM. Following instructions over her mobile phone, she actually transferred 490,000 yen to the scammer's account. She had no time to check the amount displayed on the ATM screen, pressing buttons exactly as instructed.
The classic pattern of refund fraud is using a small refund as bait to lure victims to an ATM. Government agencies never instruct people to complete procedures at an ATM over the phone. Please also refer to countermeasures against tax refund scam calls. Refund procedures are always communicated in writing and handled at a service counter.
Case 4: A Call Impersonating the Pension Office
Mr. D, a man in his 70s, was contacted by someone claiming to be from the pension office: "There was an error in your pension calculation, and we need to refund 52,000 yen." He was told the procedure required a bank ATM and was directed to a convenience store ATM. Following the phone instructions, approximately 800,000 yen was withdrawn. Mr. D noticed something odd when a "transfer amount" screen appeared, but the scammer explained it as "the screen for receiving your refund," and he continued the operation.
Refund scammers exploit the fact that victims are unfamiliar with ATM operations, misrepresenting what the screen displays. There is no ATM operation for "receiving money." Remembering this single fact is enough to prevent refund fraud.
Bogus Billing Cases
Case 5: Threats Disguised as Unpaid Fees
Mr. E, a man in his 50s, received a call from an 050 number: "You have unpaid fees for a paid website. If you do not pay today, we will take legal action." Although he had no recollection of using such a site, the threat that "your employer will find out if it goes to court" frightened him into purchasing 300,000 yen worth of electronic money cards at a convenience store and sharing the codes. The scammer explained it as "a settlement payment to drop the lawsuit," and Mr. E's fear of his company finding out prevented him from thinking clearly.
Bogus billing scams use legal terminology like "legal action," "lawsuit," and "asset seizure" to instill fear. Legitimate billing always arrives in writing, and no legitimate creditor demands same-day payment by phone. Furthermore, no legitimate payment method involves sharing electronic money card codes.
Case 6: A Billing Scam Impersonating a Telecom Company
Ms. F, a woman in her 40s, received a call from someone claiming to be a major telecom company's customer center: "Unauthorized access has been detected from your line. A security fee of 150,000 yen is required." She transferred the money to the designated account. When she later called the telecom company back through its official number, she was told no such call had been made. The scammer had known some of Ms. F's personal information, including her plan and contract duration, which added credibility.
Leaked personal information is used as material to make scam calls sound credible. Understanding data breaches and phone number exposure risks and knowing where your information might leak from is important.
Common Patterns Found Across Cases
- Creating urgency - "By today," "within the next hour" - denying victims time to think
- Leveraging authority - Impersonating trusted organizations like police, government offices, or major corporations
- Instilling fear - Suggesting serious consequences such as arrest, lawsuits, or account freezes
- Enforcing secrecy - "Please don't tell anyone else" - cutting off access to advice
- Small-amount bait - Presenting a small benefit like a refund to prompt action
- Multi-person theatrical setups - Multiple accomplices playing roles such as son, supervisor, and lawyer
Simply knowing these patterns gives you the ability to pause and think "this might be a scam" when you receive a suspicious call.
Practical Lessons to Avoid Becoming a Victim
Establish a Family Code Word
As a countermeasure against impersonation scams, agreeing on a code word within your family is highly effective. Set a rule that whenever money comes up in a phone call, the code word must be confirmed. Change the code word periodically and choose something all family members can easily remember.
Hang Up and Verify
When you receive a call from someone claiming to be from a public agency or company, hang up and call back using the official phone number. Use the number listed on the official website or in the phone directory, not a number provided by the caller. If the matter is legitimate, they will never refuse a callback.
ATMs Cannot Process Refunds
Government agencies will never instruct you to operate an ATM over the phone. The moment someone says "please go to an ATM," treat it as a scam. ATMs are machines for withdrawing and transferring money - there is no operation for "receiving money."
Use Consultation Hotlines
If you receive a suspicious call, consult the police consultation hotline (#9110) or the consumer hotline (188). Please also refer to how to report phone scams. Getting a third party's opinion rather than deciding alone is the key to preventing fraud.
Summary
Phone scam tactics are numerous, but analyzing these cases reveals common patterns. Psychological manipulation combining "urgency," "authority," and "fear" is the foundation, and calls exhibiting all these elements demand maximum vigilance. Discuss countermeasures regularly with your family and make it a habit to "hang up and verify" when you receive a suspicious call. Building a knowledge base of these cases is your greatest weapon for making calm decisions when the moment comes.
