摘要：This article takes a close look at the world-leading Japanese mobile data market
which is all about migrating users to 3G (third generation of mobile communication technology)
and offering new cutting-edge services driven by more powerful 3G networks and devices. Its
special focus is on the mobile music market which generates 50 % of mobile content premium
revenues. Learning from Japan makes sense as there are basically no differences between end
user cultures in Japan and other countries, but there still are many differences between management
cultures.
