.jp domain list
There are 1,095,400 registrable .jp domain names in our data, with 2,168,318 subdomains under them, in the release updated 16 October 2026 — names only, as historical observations, not proof that a name resolves or is in use today.
The subdomain file has 2.0 .jp names for each registrable .jp domain in the domain file, against 4.0 across all top-level domains. This is a ratio of file rows, not a typical count for one site: many domains have no subdomains in the file. The most common tracked leftmost label is www (1,029,573 names, 47.5% of .jp subdomains). 31.0% of .jp domains sit under a second-level suffix such as co.jp.

Getting only .jp
The release is sold as two complete files covering every TLD in it, not as per-TLD lists. To keep only .jp, filter the files you download, for example:
zgrep -E '\.jp$' getdomainlists-2026-10-16-domains.txt.gz > jp-domains.txt zgrep -E '\.jp$' getdomainlists-2026-10-16-subdomains.txt.gz > jp-subdomains.txt
Try the format first with the free 1,000-name samples. Both full files are $9 once, with 30 days to download.
Limits
- Historical observations collected up to this release (updated 16 October 2026); not proof that a name is registered, resolves or is in use today.
- Coverage is incomplete and uneven; these counts describe this release, not the whole .jp namespace.
- Names only: no owner, contact, hosting or registration-date data.
