These checks passed — but they don't clear the site. A clean antivirus result, valid SSL, and a calm server only mean it isn't hosting malware; they say nothing about whether the business is real. This verdict is based on the site's conduct and content, not a malware detection.

Confidence
The domain niwayosisaiseki.com belongs to 株式会社丹羽由砕石 (Niwa Yoshi Saiseki Co., Ltd.), a construction-materials company in Shiga/Kyoto that claims 55 years of operation as of 2022. The page content, written in Japanese, describes a legitimate business supplying aggregate and construction materials to regional infrastructure projects. However, six antivirus engines—including BitDefender, CyRadar, Fortinet, ADMINUSLabs, Chong Lua Dao, and CRDF—flag the domain as phishing or malicious, which is unusual for a genuine corporate site. Independent trust aggregators rate it 40/100 (questionable). The domain is 3,193 days old (nearly 9 years), has valid SSL, and the hosting IP shows no abuse history, all consistent with a real business. The absence of contact email, phone, or address on the page is atypical for a company claiming active operations, though this may reflect a minimal web presence rather than intent to defraud. The antivirus detections may reflect a false-positive cluster or a compromised page element, but the combination of detections and poor trust scores warrants caution.
Full dossier
Analysis complete

Page Content

The page is a Japanese-language corporate site for a construction-materials supplier. It describes the company's 55-year history, mission to support infrastructure development through resource recycling, and operations in Shiga and Kyoto. The copyright notice is dated 2017. Navigation includes company overview, factory details, history, business operations, recruitment, contact, links, and terms of use.

Infrastructure

Domain registered 3,193 days ago (approximately 9 years) via GMO Internet Group (Onamae.com). SSL certificate is valid (Let's Encrypt R12) with 59 days remaining. Hosting IP 183.181.97.23 has zero abuse reports and a clean reputation score. No redirects or homoglyph tricks detected.

Domain History

The domain is well-established with nearly a decade of registration history. WHOIS privacy is disabled, suggesting a legitimate business registration. The age and stability are consistent with a real operating company.

Web Reputation

Six antivirus engines flag the domain as phishing or malicious: BitDefender, CyRadar, and Fortinet classify it as phishing; ADMINUSLabs, Chong Lua Dao, and CRDF mark it malicious. Independent trust aggregators rate it 40/100 (questionable). Browser blocklists do not flag it. The sandbox did not trigger on the page. This mixed signal pattern—legitimate business indicators but multiple AV detections—suggests either a false-positive cluster or a compromised element not visible in the static scan.

Final Verdict·niwayosisaiseki.com
DANGEROUS

A Japanese construction-materials company with a legitimate 55-year history, but 6 antivirus engines flag it as phishing or malicious, and independent trust aggregators rate it poorly. The site lacks contact details and shows no web presence, raising questions about the flagging accuracy.

Do not enter payment or personal information on this site without independent verification of the company's legitimacy through Japanese business registries or direct contact via phone. If you are a supplier or customer, verify the company's details through official channels before proceeding.
