No automated scan can guarantee that a website is safe.

Independent evidence brief

What we observed about mainichi.jp

Updated Sep 26, 2026

The latest scan examined 10 public pages on mainichi.jp. Website descriptions below come from the site itself. Registration, connection and threat findings were checked separately.

Purpose and visible content

On its homepage, the site says: 毎日新聞デジタルは毎日新聞のニュースサイト。政治、経済、国際、事件、話題、スポーツなどの速報、写真、動画、英語版(The Mainichi)を掲載しています。

Registrar and domain history

A reliable creation date was not returned by the registration lookup. The report leaves domain age unverified rather than guessing.

Connection and hosting evidence

The checked homepage returned HTTP 200 in about 1000 ms.

A valid TLS certificate was observed, expiring Feb 26, 2027.

Threat checks and score context

External malware-provider coverage was unavailable. The report does not treat this missing check as a clean result.

Safety Score: 59/100. Evidence Confidence: 65%. These measure different things.

Latest recorded material change: The captured website appearance changed.

Server-side analysis

Automated security checks

Homepage HTML only · Eight local rule families · local-security-v1

Checks use the fetched page and redirect chain. Scripts are not executed, forms are not submitted, and linked files are not downloaded. This is not a malware clearance.

No listed local patterns observed. The limited rule set cannot detect every threat or behavior.

External threat intelligence

Provider coverageNot checked

Local checks do not query external reputation databases. An unavailable check is never a clean result.

Questions about mainichi.jp

FAQ

Still have questions? Contact us →
Is mainichi.jp safe to visit?

The latest Safety Score is 59/100 with 65% Evidence Confidence. This is a point-in-time assessment of observed technical signals, not a guarantee. Check the exact address and avoid entering payment details if anything looks unusual.

Did the scan detect malware on mainichi.jp?

External threat-provider coverage was unavailable for this scan, so malware status is unverified.

When was mainichi.jp registered?

The registry lookup did not provide a reliable creation date in this scan.

Did mainichi.jp have a valid TLS certificate?

The scanner observed a valid TLS certificate using TLSv1.3. A valid certificate alone does not establish that the site is safe.

Can a paid listing change this website's score?

No. Premium placement and owner-supplied pages are labelled separately. Technical evidence, the Safety Score and moderation decisions remain independent.
