Yesterday Apple finally managed to get iTunes Music Store open in Japan . Apple, based in Cupertino, California, said iTunes would charge ¥150, or $1.34, each for 90 percent of its songs and ¥200 for the other 10 percent, undercutting some services, like Sony’s Mora, which charges ¥210. (...) Offerings from Japanese artists on Sony labels will not be available on iTunes, said a spokeswoman for Sony Music Entertainment, Kiyono Yoshinaga. “We are in talks with Apple, but we have not reached an agreement at this time,” she said, declining to give details.
