The Close Link Between Seasons and Phone Scams
Phone scam tactics are not constant throughout the year - they shift strategically to align with seasonal events and administrative schedules. Fraud groups exploit current social concerns to boost credibility, so understanding seasonal patterns is a critical first step in prevention. Because different tactics cluster at different times of year, knowing these seasonal factors makes suspicious calls easier to spot.
Fraud groups have an intimate knowledge of administrative calendars and social events, exploiting victims' tendency to think "it's that time of year, so this must be real." Knowing seasonal patterns in advance helps you maintain heightened awareness when suspicious calls arrive.
Spring (March-May) Scam Trends
Spring brings a concentration of fiscal year-end administrative procedures, making it one of the most active seasons for fraud groups.
Tax Filing and Refund Scams
Tax refund scams rise during and just after filing season (February through spring). Scammers pose as tax office staff, claiming medical expense refunds or residential tax overpayments, then direct victims to ATMs. People who have just filed their returns are especially susceptible.
New Life Scams
Scams exploiting moving, enrollment, and employment-related procedures increase. Callers impersonate utility companies or internet providers, claiming "You need to switch your contract," to harvest personal information.
Investment Scams Targeting New Graduates
Inexperienced new employees are targeted with investment pitches. "Start building wealth now" and "Your senior colleagues are already in" are used to push cryptocurrency or unlisted stock investments.
Summer (June-August) Scam Trends
Summer sees scams piggybacking on gift-giving season, travel, and natural disasters.
Mid-Year Gift Scams
Scammers impersonate delivery companies, claiming to "confirm the delivery address for a gift." They may use real department store or e-commerce site names, exploiting the active gift-exchange period to seem credible.
Travel Scams
Advance-payment fraud using cheap travel deals increases. "A cancellation opened up a special rate" or "A deposit is needed to secure the booking" are used to collect travel payments for nonexistent trips.
Disaster Relief Scams
After typhoons or heavy rains, fake charity scams appear. Scammers appeal to goodwill with "Please donate to disaster relief" and direct victims to fraudulent accounts. Extra caution is needed immediately after disasters.
Autumn (September-November) Scam Trends
Autumn sees pension-related and leisure-season scams.
Pension Scams
Scams impersonating pension offices increase around pension payment months (even-numbered months). "We need to refund an overpayment" or "There's an issue with your eligibility" target elderly victims. Extra vigilance is needed around payment dates.
Early Year-End Gift Scams
Year-end gift scams begin around November, with scammers posing as department stores or online retailers offering "early-bird discounts" or "limited product reservations" that require advance payment.
Winter (December-February) Scam Trends
Year-end and New Year see heightened financial activity, and fraud groups intensify operations accordingly.
- Year-end deadline scams: "The procedure must be completed within the year" exploits holiday busyness to impair judgment
- Gift delivery scams: Impersonating delivery companies to harvest personal information under the guise of address confirmation
- Year-end bank transfer fraud: "Before the banks close for the holidays" adds time pressure
- New Year greeting scams: Impersonating business contacts or acquaintances, transitioning from New Year pleasantries to financial requests
Year-Round Prevention Practices
Regardless of season, practicing these measures daily significantly reduces your fraud risk.
- Stay informed: Regularly check NPA and Consumer Affairs Agency alerts for new tactics
- Share with family: Discuss seasonal scam trends with family, especially elderly members
- Verify phone numbers: Search suspicious numbers on phone lookup services before responding
- Never decide on the spot: If asked for money or personal information by phone, always hang up and verify independently
- Use spam call filters: Enable carrier or app-based filters to automatically block known scam numbers
Seasonal Damage Trends
The seasonal breakdown of special fraud overall varies year to year, but different tactics tend to cluster in particular periods:
- Spring (March-May): Tax refund scams tied to filing season, and scams posing as contract procedures for new-life transitions, stand out
- Summer (June-August): Watch for advance-payment travel scams and charity scams posing as disaster relief after typhoons or heavy rains
- Autumn (September-November): Pension-related scams timed to payment months, and the start of the year-end gift season
- Winter (December-February): Bank transfer fraud exploiting the year-end rush, and scams using deadlines to pressure victims, increase
For refund scams specifically, NPA monthly data (2024) shows recognized cases peaking in April (437), clustering in early spring alongside March (391) and May (390), and reaching their lowest in December (249). Many people assume refund scams spike at year-end, but recognized cases are actually lowest in December - understanding these differences in seasonal tactics is what matters most.
Seasonal Prevention Checklists
Review these season-specific points and heighten your guard during the relevant periods.
Spring (March-May)
- Have you received a "refund" call after filing taxes? Any instruction to use an ATM is 100% fraud
- Is a "utility contract change" call related to your move from a legitimate provider? Never share meter reading information
- Watch for investment pitches targeting new graduates - "guaranteed returns" and "risk-free" are scam hallmarks
Summer (June-August)
- Be alert to post-disaster charity scams - donate only through official websites of established organizations like the Japanese Red Cross
- Watch for travel advance-payment scams - be suspicious of deals that seem too cheap
Autumn (September-November)
- Be alert to pension scams around payment months - pension offices never request personal information by phone
- Watch for gift delivery scams - never tap links in delivery notification SMS messages
Winter (December-February)
- Be wary of "must complete today" year-end calls - time pressure is a classic scam tactic
- Watch for New Year greeting scams - even calls from apparent business contacts warrant suspicion if money comes up
Event-Driven Scams
Beyond seasonal patterns, scams also exploit major social events.
Election-Related Scams
Around national and local elections, scammers claim "election-related refunds" or "polling location change procedures" to harvest personal information. Election commissions never request personal data by phone.
Policy Change Scams
My Number Card rollout, invoice system introduction, health insurance card discontinuation - scammers exploit every administrative change. "You must complete the transition procedure" or "Failure to act will result in penalties" create false urgency.
Pandemic-Related Scams
During COVID-19, massive volumes of scam calls impersonated "relief payment applications" and "vaccine appointment bookings." Similar tactics tend to emerge whenever a health crisis spreads. Always verify government communications through official websites.
