Check unknown Japanese numbers with recent reports (Tokyo, Osaka, Nagoya, Kyoto) and share your experience.
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.

The caller introduced themselves as being from USEN and offered a gift, but it turned out to be a sales pitch for water services, which was immediately declined.

Recently, this number has been calling nonstop, which is very annoying.
I received a call from an unknown number around 5 pm, which turned out to be a solicitation call from ｺﾐｭﾌｧ光, a company I'm already a customer of
I received a call at 16:18 on April 12, 2017, and although I thought it was my first time, the comments suggested it might not have been; this call justifies the use of phone call blocking, but the feeling is not good, so I took note of it and recommend adding it to the nuisance list
Persistent solicitation; when I firmly declined, they gave me the silent treatment and hung up. It was upsetting, and I'm cancelling my Comufa.
I accidentally picked up, but the other party didn't say a word, it was eerie and made me feel bad.
The repeated calls are really annoying and make me feel uneasy.
The persistence of these calls is not only annoying but also excessive, with three calls in just two minutes, and the carrier should consider suspending this number due to its malicious nature.
It's annoying, I want to quit Comifa
Persistent and unprofessional, not wanting any dealings with such a company
Repeated calls are a nuisance
I hate solicitation calls.
Upon being solicited, I felt uneasy

Use the official website/app number; avoid calling back the unknown number; check in‑app messages.
No. Portability/VoIP make 03/06/052/075 and 070/080/090 unreliable as proof of origin.
Delivery updates, bank callbacks, 2FA codes; robocalls, parcel/account phishing, scripted sales calls.
