| % whois 59.106.13.181 | grep support
| remarks:        Email address for spam or abuse complaints : support at sakura.ad.jp

That's not a special whois client but is in the text returned by APNIC.

note that whois.nic.ad.jp does not, unlike RIPE whois, automatically 
also include person objects referenced in an inetnum object, so you 
will have to query for those separately, as another poster pointed out.
