What is this website?

日本の女優第一号として名をはせた川上貞奴と電力王と言われた福沢桃介が共に暮らした家です。創建当時は、文化のみちエリアの北端、東二葉町にあり、2000坪を超える敷地に建てられた和洋折衷の建物は、その斬新さと豪華さから「二葉御殿」と呼ばれ、政財界人や文化人の集まるサロンとなりました。当時、慶応義塾の先輩である矢田績に招かれ、「名古屋電燈(株)」の取締役に就任した桃介は、木曽川での水力発電を進める為に名古屋に拠点を構え、事業パートナーとして貞奴を呼び寄せたとも言われています。設計は、当時新進気鋭の住宅専門会社「あめりか屋」に依頼し、建物内部に驚くべき電気 装備が施される一方、貞奴の好みも至る所に取り入れられました。当時の記録では、玉砂利の道を入っていくと、車寄せの前がロータリー。松の木などが植えられ、芝生の庭にはしだれ桜やもみの木、電気仕掛けの噴水やサーチライトがあったようです。円形に張り出したソファがある大広間では、ステンドグラスが柔らかい光を投げかけていたことでしょう。

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 5000 ms.

A valid TLS certificate was observed, expiring Feb 13, 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: 58/100. Evidence Confidence: 70%. These measure different things.

Sampled scripts and pages

Resource analysis incomplete

6 resources checked · 10 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.

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.

SPFPolicy record observed, not fully validated
DMARCNo matching record returned for this exact hostname

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.

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: 2026-10-24T02:40:09.471Z.

jquery 3.7.1 No known advisories matched this version in the database snapshot.
jquery-migrate 3.4.1 No known advisories matched this version in the database snapshot.

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

Apache HTTP ServerReview the Apache branch and keep security patches current. Avoid exposing detailed server version headers.
jQueryConfirm the observed jQuery version is supported by your application and update it through your normal dependency process.
