Reverse Phone Lookup in Japan — Recent Community Reports
Check unknown Japanese numbers with recent reports (Tokyo, Osaka, Nagoya, Kyoto) and share your experience.
Unknown calls in Japan
Unsure about a Japanese number? Explore concise community notes to judge calls and texts. Around Tokyo, Osaka, Nagoya and Kyoto you’ll see both legitimate callbacks (deliveries, banking, appointments) and waves of robocalls or phishing. Area codes such as 03 (Tokyo), 06 (Osaka), 052 (Nagoya), 075 (Kyoto), and mobile ranges 070/080/090 are helpful context but not proof of origin due to portability and VoIP — treat them as signals, not certainty.
Verification: return calls via the official number listed on the company website/app, check in‑app notices, and never share one‑time codes by phone. Use device/carrier blocking for repeat issues and leave a short, factual note here (caller type, purpose, date, cues) so others benefit.

Common patterns?
Delivery updates, bank callbacks, 2FA codes; robocalls, parcel/account phishing, scripted sales calls.
What to include in a report?
Caller type, purpose, date/time, and cues that guided your decision.
