Video website YouTube should proactively check if videos infringe copyright, a group representing Japanese rights holders has said.
The Japan Society for Rights of Authors, Composers and Publishers wants videos checked before they go online.
More than 100m videos are watched each day via YouTube and many are posted without necessary permissions.
Last month 30,000 clips were taken down by YouTube at the request of the Japanese entertainment group.
YouTube's policy has been to remove clips that infringe copyright after it receives complaints.
