Visitor opinions remain separate from the technical Safety Score.

We sampled public pages from this website to understand its subject and contact paths. The titles and short descriptions below come from the website itself. They are not endorsements or independent safety findings.

These phrases were extracted locally from sampled public page metadata. They are observations, not search-volume or ranking estimates.

Local antivirus and phishing checks

Sampled scripts and pages

Resource analysis incomplete

6 resources checked · 22 script links observed on the homepage. Partial resource coverage.

ClamAV inspects the fetched homepage HTML on our server. New scans also sample up to four linked scripts and two collected internal pages, with size and time limits. Scripts are not executed. Other downloads, private server files and logged-in pages remain outside this check. A signature match needs investigation and can be a false positive. No match is not a whole-site safety guarantee.

Exact hostname lookup uses a downloaded Phishing.Database snapshot. It does not send this domain to an external lookup API or mark sibling subdomains as harmful. Not listed does not mean safe. Snapshot age is download age, not proof that every entry was recently revalidated.

Homepage HTML only · Eight local rule families · local-security-v2

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.

Page resource inventory

Counts describe the sampled HTML, not every resource loaded by the browser. External resources are common and are not automatically harmful.

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

External threat intelligence

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

A compact view of the connection, DNS and security surface. These observations describe what the scanner could verify at scan time and do not prove ownership or ongoing availability.

These counters describe the fetched response and sampled HTML. Script counts describe references in the markup, not a complete browser network log. Cookie counts cover observed response headers.

DNSKEY presence does not verify the DNSSEC signature chain. Missing records can mean no record was returned or the lookup was unavailable.

DNS observations · no external lookup API

Domain email protection

Exact-host SPF and DMARC observations help the owner investigate email impersonation risks. They are separate from website malware checks and do not change the Safety Score.

What to do next

Review the records with your mail administrator. Inventory legitimate senders and test SPF and DKIM alignment before enforcing a stricter DMARC policy. Fix duplicate records and investigate overly permissive SPF rules.

This bounded check does not send email, probe SMTP, evaluate recursive SPF includes, verify DKIM signatures or apply organizational-domain DMARC inheritance. A missing subdomain record does not prove that no inherited protection exists. A DNS timeout is unknown, not an absent record. A policy record is not proof that messages authenticate successfully.

No readable security.txt file was observed at the standard locations. This is informational and is not evidence of malware.

Header evidence is unavailable. Missing data is not treated as a clean result or proof of compromise.

No Set-Cookie header was observed on the sampled homepage response. Other pages may set cookies separately.

Versions are shown only when publicly exposed by the page or response headers. An observed version is not, by itself, proof of a vulnerability.

JavaScript library advisories

4 sampled JavaScript files checked locally with Retire.js. Database snapshot: 2026-10-23T02:40:09.003Z.

A version match is not proof that the website is infected or that an issue is exploitable here. Owners should review the advisory, check whether their code is affected and test an update. Up to four external script files are sampled, not every dependency, inline script or dynamically loaded resource.

Recommended maintenance checks

伊豆大島は都心から120km南の洋上に浮かぶ伊豆諸島最大の島です。島の中央部には標高758mの三原山がそびえ、現在も火山活動を続けています。また、富士箱根伊豆国立公園に属し、島の約97％が自然公園法によって規制されているため、自然景観と生態系が十分に保護された美しい島です。

A comparison will appear after the next completed scan.

These independent reports share an observed category or website topic with izu-oshima.or.jp. A match is a way to explore similar websites, not proof of common ownership or equal safety.
