Digital Cities: Japan Broadband Case Study

Scott Wilkinson, a VP for Hitachi Telecom, gave a talk about broadband in Japan. The typical broadband fiber connection in Japan is 100 megabits/second, and typically costs about $58/month; costs have dropped 66% in the past four years. Most broadband connections in Japan are data only, so the "triple play" is not a big consideration. The connections support video on demand, which is very popular, but there is no broadcast television content. The connections work very well for video on demand, with near real time viewing (i.e. no long wait to download before viewing).

Fiber To The Home (FTTH) is growing rapidly in Japan, and the big loser is cable modem service. The electric companies in Japan are NOT offering Broadband over Powerline (BPL), but instead are selling fiber service, which should be a clue to communities that think BPL is the way to go.

ADSL is seen as a problem in Japan, even though it has a high subscriber base. ADSL and VDSL are both available and offer much higher data rates than typical DSL services in the U.S., but the distance senstivity is a big issue, as subscribers just a few blocks away from each other can end up with very different levels of service.

The typical range of applications in Japan are very similar to the applications and services in the U.S., but the Japanese service providers have found that when people are given more bandwidth, they use it, which refutes the telco argument that no one has a need for high bandwidth connections. One of the trends is more work from home and from remote locations; the high bandwidth supports high quality videoconferencing and actually often provides a better level of service than is available in some business offices. So affordable broadband has become an engine for new kinds of work opportunities.

Services in Japan are driving demand, not connections. As more services ae available, more people sign up for high speed connections. The installation fee for fiber averages $150, so that can be a source of funding to help pay for community fiber builds. Fiber systems in Japan are profitable, with fees distributed this way:

  • Business expenses - 18%
  • IP network cost - 22%
  • Indoor wiring cost - 4%
  • Outside line cost - 45%
  • Profit - 11%

The 11% return is very good--much higher than for many other kinds of businesses, and shows that fiber networks can be operated with a positive cash flow and enough income to cover debt service.
