Description of problem: The JP domain whois server has changed. A new shared gateway at "whois.jp" will handle all JPNIC IP address and JP queries. Official details at: http://www.nic.ad.jp/en/topics/2005/20050318-01.html
Thanks for your report. This will be fixed in RHEL 5. A RHEL update containing an updated list would be very likely already obsolete by the time it gets thoroughly tested and issued as a part of an RHEL update release. The upstream configuration file available at http://savannah.gnu.org/cgi-bin/viewcvs/*checkout*/jwhois/jwhois/example/jwhois.conf?rev=HEAD&content-type=text/plain contains updated data about the JP whois servers, you can use it instead of /etc/jwhois.conf shipped in the RHEL jwhois package.
