.jp WHOIS lookup

.jp is managed by Japan Registry Services Co., Ltd.. Its registry has no RDAP service yet, so a lookup here shows the domain's DNS setup, and full details come from its WHOIS server, whois.jprs.jp, or the registry's website.

What a .jp lookup shows

The nameservers and the mail setup read from DNS. Registration details need the registry's own lookup until it offers RDAP.
