Independent evidence brief

What we observed about tca.ac.jp

Updated Nov 2, 2026

The latest scan examined 5 public pages on tca.ac.jp. Website descriptions below come from the site itself. Registration, connection and threat findings were checked separately.

Purpose and visible content

On its About page, the site says: 開校以来、「実学教育」「人間教育」「国際教育」の理念の下、即戦力となる職業人教育を行ってきた本校学科も、文部科学省が創設した学校制度「職業実践専門課程」に認定されました。

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 3000 ms.

A valid TLS certificate was observed, expiring Jan 22, 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: 60/100. Evidence Confidence: 60%. These measure different things.

Questions about tca.ac.jp

FAQ

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

The latest Safety Score is 60/100 with 60% 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 tca.ac.jp?

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

When was tca.ac.jp registered?

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

Did tca.ac.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.

How does tca.ac.jp describe itself?

The website's About page describes its purpose in the report above. This is publisher-supplied information and is separate from independent security findings.

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.
