Apple's iTunes Music Store Japan will be gaining more content from Wednesday with the addition of songs from Victor Entertainment.

The recording label, which is affiliated with Victor of Japan Ltd (JVC), will add 18 albums totalling 209 tracks to Apple's online music distribution service, it said. The tracks cover mainly Japanese domestic artists.

The iTunes Music Store launched in Japan in August this year with the support of Toshiba-EMI, Columbia Music Entertainment and Avex Group Holdings.

Users downloaded one million tracks in its first four days of operation, but its success has been limited by the absence of several major Japanese record labels. The result is that tracks from only three of the year's top 10 best-selling pop artists are available through iTunes Music Store Japan, and in two of those cases the available tracks are only a small fraction of what was released during the year.
