Common Japanese phone scams

These are the most-reported caller fraud patterns in Japan right now.

Ore-ore Sagi (It's Me Scam)

HIGH RISK

Callers impersonate a relative (typically a son or grandson) claiming to be in trouble — an accident, arrest, or hospital — and urgently need cash sent through a courier or transfer. This is Japan's most prevalent phone fraud. Never send cash based on an unsolicited phone call. Verify by calling the relative directly on their known number.

NHK / NTT Impersonation Calls

HIGH RISK

Fraudsters impersonate NHK fee collectors or NTT technical staff threatening disconnection or fines. NHK collectors only visit in person with official ID; NTT does not call about technical issues unsolicited. Report to the National Consumer Affairs Center of Japan (PIO-NET) at 188.

Fake Investment Seminar (Toushi Shoho)

MEDIUM RISK

Callers offer exclusive investment seminars or trading signals promising high returns on stocks or crypto. These often target older adults. The FSA (Financial Services Agency) warns against unregistered investment advisors. Verify firms at fsa.go.jp before any investment.
