.co.jp domains list

What is .co.jp TLD

The .co.jp TLD is the commercial second-level namespace under Japan’s country-code .jp, assigned to incorporated entities legally registered in Japan. Registration is restricted and typically limited to one name per company, which means .co.jp domains map closely to verifiable organizations. In practice, .co.jp websites function as canonical homes for corporate disclosure, product information, and domestic customer support. From our coverage, we see concentrated use by listed companies and subsidiaries operating in Japan, with consistent naming conventions and mature hosting stacks. These characteristics produce strong identity signals for brand protection and supply-chain due diligence. We index and analyze this namespace to surface infrastructure, security, and content patterns at scale. Explore webatla’s .co.jp domain datasets today.

History and key features of .co.jp TLD

Established early in Japan’s internet development as a category under .jp, .co.jp has been operated under policies maintained by Japan’s .jp registry (JPRS) with oversight arrangements that emphasize verified corporate eligibility. Key features include local-entity requirements, generally one delegation per legal entity, and predictable naming hygiene that reduces brand collisions. Technically, .jp supports DNSSEC and robust anycast distribution, benefits inherited by .co.jp domains. In our longitudinal scans, .co.jp websites exhibit stability in host providers, steady TLS adoption, and lower churn relative to many open commercial namespaces, reflecting corporate governance cycles. These conditions make the zone a reliable corpus for market mapping, vendor risk analysis, and historical ownership tracking. Review webatla’s longitudinal datasets on .co.jp domains.

Why and who choose the .co.jp domain

Organizations select the .co.jp domain when they need to show formal incorporation and active operations in Japan. Eligibility focuses on registered companies and comparable legal entities, making .co.jp domains suitable for headquarters sites, investor relations, and nationwide customer services. Foreign groups often adopt .co.jp websites for local subsidiaries to align with procurement standards, data residency expectations, and consumer trust. We observe co-registration with .com and second-level .jp, Japanese hosting footprints, and bilingual content strategies that improve discoverability and governance clarity. This choice fits sectors where authenticity, auditability, and long service lifecycles matter, including finance, manufacturing, and technology. Our analytics quantify infrastructure choices, uptime posture, and vendor dependencies across this constrained zone. Explore segmentations in webatla’s .co.jp domain datasets.
