Characteristics of the Japanese Mobile Telecommunications Market
As of March 31, 2015, cumulative mobile communication subscriptions in Japan totaled 150 million , up 5.4% year on year.
Smartphone subscriptions increased, due mainly to the transition from feature phones, boosting the smartphone penetration rate to 60.6%  on a household basis as of March 2015. As the penetration rate is still low in comparison with countries that are more advanced in this respect, such as the United States and South Korea, we expect the rate to grow further.
The Japanese market is characterized by the advancement of LTE networks, which enable high-speed data communications, leading to the creation of communications environments that facilitate diverse services and are independent of handset and location. Against this backdrop, the trend toward "multi-devices," in which a customer may also own a tablet or Wi-Fi router, is gaining traction, so the Japanese mobile telecommunications market is projected to continue expanding.
Furthermore, advances in networks and handsets are making mobile usage environments more convenient, and the scale of the mobile content and mobile commerce markets is increasing. This scenario points to further opportunities to generate revenues.

Fixed-line broadband service penetration is almost at 70%. Amid a gradual market expansion, in March 2015 regional NTT companies began wholesaling fiber access services (FTTH).

Due to the proliferation of smartphones and tablets, mobile traffic in Japan is growing at a rapid pace, with average monthly traffic recently rising at 44% year on year.
In particular, average traffic during the peak hours for mobile customers (11-12pm) is up by around 50% per year. This situation poses a dilemma for mobile telecommunications companies, which are working to efficiently absorb this increase in mobile traffic while restraining capital expenditures and maintaining stable network operations.
