MTV Japan and its mobile partner, Yamaha Corp., announced today (Feb. 16) that a new telecom operator has signed on for Japan's first music-recognition service, MTV Music Finder.

Japan's second-largest telecom operator, KDDI, will provide the service to its customers. The deal brings MTV Music Finder's total customer base to 40 million.

MTV Japan and Yamaha launched MTV Music Finder last July on the Vodafone Japan network. The service is provided in cooperation with SystemK, which localized for Japanese mobile platforms the song-recognition system developed by British company Shazam Entertainment.

After registering with the service, users can identify tracks by dialing 9963 on their handset and holding it toward the music source. A message is then sent to their mobile phone with the name of the artist and song.

MTV Music Finder will change its pricing structure. Users will pay 210 yen ($2.01) for three song recognitions a month, vs. the current 315 yen ($3.02) for five recognitions. Consumers have access to 2.5 million tracks and selected ringtones.

Toshiaki Takeuchi, SystemK's director of international business development, says talks are under way to make MTV Music Finder available to NTT DoCoMo i-mode, Japan's biggest mobile web-access service.
