Online Scams in Japan: Complete Guide 2026
Japan's National Police Agency reported over ¥87.3 billion (approximately $580 million) in online fraud losses in 2025. While Japan has historically had lower fraud rates than Western countries, the shift to digital services and cashless payments has opened new attack vectors. Japan faces a unique mix of traditional phone scams and modern cybercrime.
Ore Ore Sagi (It's Me Scam)
Japan's most infamous scam — ore ore sagi (オレオレ詐欺, "it's me, it's me" scam) — has evolved from simple phone calls to sophisticated multi-person operations. Scammers call elderly victims pretending to be a grandchild or family member in trouble: involved in a traffic accident, facing arrest, or owing money urgently. The phrase "ore ore" ("it's me") exploits the Japanese cultural tendency to not question family members directly.
"Okaasan, ore da yo, ore. Jiko ni atte, keisatsu ga kite iru. Sugu ni okane ga iru..." (Mom, it's me, it's me. I was in an accident, the police are here. I need money right away...) — The opening of an ore ore sagi call. Losses from these scams exceed ¥30 billion annually in Japan.
In 2026, AI voice cloning makes these scams more convincing. Japan's police have launched ATM withdrawal limits and bank teller intervention programs to combat ore ore sagi, but awareness remains the best defense. Establish verification protocols with family members.

Phishing (Fishing/フィッシング)
Phishing emails and SMS impersonate Amazon Japan, Rakuten, eki-net (JR train reservations), Mercari, Yahoo Japan, and Japanese banks. Fake Amazon Japan messages about account suspensions are the single most common phishing attack. Messages impersonating mobile carriers — NTT Docomo, au (KDDI), and SoftBank — about unpaid bills or account issues are also prevalent.
Always verify by accessing services directly through official apps or bookmarked URLs. Never click links in messages claiming account issues.
Fake E-commerce Sites
Fake online shops with Japanese-language interfaces sell branded goods at steep discounts. Many target consumers searching for specific products on Google. The sites accept credit card payments, capture card details, and either never ship or send counterfeit goods. Some accept 銀行振込 (bank transfer) only, ensuring no chargeback is possible.
Investment and Cryptocurrency Scams
Romance-linked investment scams (known as 国際ロマンス詐欺 in Japan) have surged, often operating through LINE and other messaging apps. Victims are groomed through fake romantic relationships and directed to fraudulent crypto trading platforms. Japan's FSA maintains a list of unregistered crypto exchanges — always verify before investing.
