These images were either discovered on the sites below themselves or on one of their Way Back Machine / Internet Archive's copies:
* Main site: http://www.h4.dion.ne.jp/~maih/
* Still live: http://jubee.muvc.net/ or http://www.muvc.net/jubee/
* Now dead: http://jubeeyamada.tripod.com/ http://maih.netfirms.com/
The Way Back Machine / Internet Archive's media size limit prevented the recovery of a few animations that it would have backed up otherwise so there is still plenty of lost content to find out there somewhere. Maybe this artist had setup other temporary versions of their site that an e-hentai.org site member has yet to find :).
