"We think this is going to change the experience of discovering and buying and enjoying music in Japan. Together with the iPod, we think we are ushering in a whole new age of digital music." The Associated Press notes that Apple has been "investing aggressively in Japan, not only by starting iTunes but also by advertising, such as iPod posters plastered on trains and opening the fourth Apple store in Japan Saturday." During the launch event, Jobs said that iTunes had been tailored for the Japanese market to include exclusive recordings and video clips by Japanese artists. With the addition of Japan, iTunes music store is now available in 20 nations, reaching 85 percent of the global music market, according to the report. Apple's drive-based iPod offerings ranked No. 1, No. 2, and No. 4 among hard-drive portable players in Japan sales, according to Gfk Marketing Services Japan in Tokyo. "Sony Network Walkman models were catching up at No. 3 and No. 5, but still apparently unable to make up for the iPod's early start," according to the AP.
