  Using Ubiquitous Networks to Create New Services Based on the Commercial and Public Infrastructure  
Michio KITAMURA
1. Reconstructing the commercial and public infrastructure through ubiquitous networks will be a major challenge that offers the potential for promoting the economic rebirth of Japan by initiating structural changes. As we propose in this report, the commercial and public infrastructure that could be realized by ubiquitous networks essentially consists of three strata: first, ubiquitous networks themselves; second, ubiquitous commercial and public infrastructure platforms; and third, applications for ubiquitous commercial and public infrastructure.
2. Looking forward, we believe that ubiquitous networks should be sufficiently broad-based to ensure applications offering "ubiquitous health and security concierge systems," "ubiquitous automobile network systems," and "ubiquitous education and learning systems." The development of such systems constitutes an important element of the process, as they would contribute to structural reforms in terms of medical care, social welfare, social capital such as roads, employment and employee training and the enhancement of skills.
3. The introduction and spread of ubiquitous commercial and public infrastructure applications will have a major economic impact. If only focused on major applications such as health and security functions, automobiles and ubiquitous education and learning, we estimate that they could generate approximately 10 trillion in economic demand, as well as having various profound economic effects on society as a whole.
4. In order to promote the development and formation of ubiquitous system applications, platforms to support them are needed. In the future, "ubiquitous personal terminals (UTs)," "ubiquitous chips (UCs)" and "ubiquitous service exchanges (UXs)" must be developed and widely spread to achieve this in Japan.
5. Measures to achieve a wider use and acceptance of ubiquitous commercial and public infrastructure applications and platforms might include (1) a private-sector approach for building and managing the proposed system, (2) structural innovation within each of the specific considerations, and (3) developing systems and applications based on time-transition scenarios.
