Japan is second to America as the largest market for music in the world.
Napster Japan, working as a joint venture with Tower Records Japan, will be making individual tracks and albums available for an average of 150 to 300 Yen (68p to £1.35) per track and users can also sign up for a monthly download service, which will provide unlimited music to their computers for 1,280 Yen (£5.76) per month.
Napster Japan also plans to take full advantage of the growing trend for downloading music to mobile devices.
Chris Gorog chairman and CEO of Napster said: "Napster is very pleased to bring the first music subscription service to Japan's vibrant music and technology market."
