Common questions
Is cao.go.jp legit or a scam?

Who owns cao.go.jp?
Nobody has completed AboutUs's owner verification for cao.go.jp. That's true of most sites here — it isn't itself a warning sign.

AboutUs has not vetted this site. Everything below is what we could measure automatically. Anything you do on the site — paying, sharing personal details, downloading — is between you and the site, not AboutUs.
Current facts
Latest available measurements; dated entries retain their dates. These are measurements, not an endorsement of the site.
not yet retrieved
Registrar and registration date not retrieved yet — we retry on every view.
We withhold an authority number until independent evidence (global rank, link-graph presence) has accrued. The facts we do have about this site are shown below — we'd rather say “not enough signals yet” than invent a low score.
Safety evidence
No unexpired threat-feed result; name-similarity check available (recorded about 67 days ago); 3/3 transport and email checks available (oldest recorded about 67 days ago). This is evidence coverage, not a probability that a website is safe.
