Twenty-four companies and orgs repping Japanese copyrights holders, including the Motion Picture Producers Assn. of Japan (Eiren), Thursday urged YouTube Japan to weed out rights violators.

The same day Google veep David Eun gave a progress report in Tokyo on a system to red-flag rights violators that should be up and running by fall.

New digital fingerprinting technology, called Claim Your Content, will automatically block suspicious video and audio clips after comparing them to a digital library of copyrighted contents. 

Launched in June, YouTube’s Japanese-language site is already its second-biggest worldwide in number of users.

Reps from Japanese rights orgs and companies met Eun and YouTube co-founders Chad Hurley and Steve Chen back in February to discuss the problem of copyrights violations on its site.

The Japanese side asked YouTube to institute a number of changes. These included: a copyright infringement warning in Japanese on the site’s top page; getting users of copyrighted contents to register personal details, including names and addresses; and canceling the accounts of users who post copyrighted content without permission.  

 But rights holders say progress has been slow, with pirated clips of Japanese TV shows, toons and other local content still rife on the site.
