Royalties are distributed to copyright holders on a quarterly basis in March, June, September and December according to the procedures stipulated in the Royalty Distribution Rules. In principle, JASRAC produces distribution documentation based on the music usage reports provided by users of musical works. With regard to the categories such as live performances and performances by means of phonograms at bars and nightclubs, a large number of musical works are continuously used every day and it is difficult to receive program return for all the works used. For such categories, documents for distributions are produced based on statistical sampling survey. For karaoke singing at bars, pubs and karaoke boxes, etc., JASRAC receives the data of work titles used at the Karaoke machines in the venues and number of use from the online karaoke operators, and makes distributions based on the data.		2.4 million works are stored in this database, which is open to the public via the Internet. Databases with information about musical works; copyright holders and music users are indispensable for the accurate and efficient administration tasks from licensing to fee collection and royalty distribution. JASRAC currently possesses detailed information on approximately 7.3 million musical works compiled from musical work documents submitted by trustors and from overseas sister societies. Among these data, information on 2.4 million works that have been used in recent years are included in the "Works Database", and various data from this database (work title, composer/lyricist, music publisher, singer, performer, etc.) are made public through the Internet and are widely accessed and used. JASRAC has constructed various databases including the right holder database that holds data on the trustors in Japan, which totals over 14,500, and copyright owners around the world that belong to CISAC member societies, and the music user database that can provide information on the businesses and individuals who are engaged in karaoke business or other uses of musical works. These databases are all interlinked to facilitate the smooth operation from licensing to royalty distribution.
