.jp domain availability and monitoring
Look up any .jp name to see if it is registered, who runs it, and when it expires. Add it to your watchlist and we check it again every night.
How we check .jp domains
The .jp registry does not publish an RDAP service yet, so we ask its WHOIS server (whois.jprs.jp) directly. When the WHOIS answer is ambiguous we fall back to a DNS delegation check and mark the result as maybe available instead of guessing.

Waiting for a .jp name?
Add the domain to your watchlist and Domain Sentinel checks it every night. You get an email the moment it becomes available, expires, or changes hands.
