Major house builders had been playing the central role in developing smart houses as residences that offer safe, secure and affluent lives. However, since the Great East Japan Earthquake, power shortages have become a serious problem and more and more entities have been introducing home energy management systems (HEMS) as a way to be self-sufficient in terms of energy and save energy in the event of a disaster. Also, consumer electronics makers and housing equipment makers have been proceeding with the development of new appliances in order to realize energy saving, energy creation and energy storage solutions for the home. One research company predicts that the market size of Japanese smart houses will reach 4000 billion yen by 2020. This paper describes the solutions that can realize Fujitsu's Smart House services which connect homes with society and communities via information and communications technology (ICT), and also create services that increase residents' QOL.

In 2014, the International Renewable Energy Agency (IRENA) published a global renewable energy roadmap–called REmap 2030–to double the share of renewables in the global energy mix by 2030 compared to 2010 (IRENA, A Renewable Energy Roadmap, 2014a). A REmap tool was developed to facilitate a transparent and open framework to aggregate the national renewable energy plans and/or scenarios of 26 countries. Unlike the energy systems models by IEA-ETSAP teams, however, the REmap tool does not account for trade–offs between renewable energy and energy efficiency activities, system planning issues like path dependency and investments in the grid infrastructure, competition for scarce resources– e.g. biomass–in the commodity prices, or dynamic cost developments as technologies get deployed over time. This chapter compares the REmap tool with the IEA–ETSAP models at two levels: the results and the insights. Based on the results comparison, it can be concluded that the REmap tool can be used as a way to explicitly engage national experts, to scope renewable energy options, and to compare results across countries. However, the ETSAP models provide detailed insights into the infrastructure requirements, competition between technologies and resources, and the role of energy efficiency needed for planning purposes. These insights are particularly relevant for countries with infrastructure constraints and/or ambitious renewable energy targets. As more and more countries are turning to renewables to secure their energy future, the REmap tool and the ETSAP models have complementary roles to play in engaging policy makers and national energy planners to advance renewables. © Springer-Verlag Berlin Heidelberg 2015.

The Japanese Government has set its sights on becoming number one in the world in ICT, as seen in the announcement of an e-Japan strategy by the IT strategy organization established in 2000. However, according to the United Nations E-Government Development Index, Japan's ranking has remained low despite its progress in information infrastructure. The reason for this is that the Japanese government did not integrate the code and standardize the data which are needed to use ICT across the whole country. The government introduced the national ID bill into the Diet last year, but the issue of Kanji characters, i.e., how to define the Japanese Kanji character set, remains unresolved because this issue, especially as it related to Kanji characters of names, includes a complex problem of interface between human and machine. I think the current proposed solution will not be successful because it ignores the issue of human interface. I insist that the Kanji character issue should be viewed from the perspective of human interface, and I propose a solution whereby the government should regulate by law the range of Kanji characters used by ICT, rather than increasing the number of Kanji character used. © 2013 Springer-Verlag Berlin Heidelberg.

Although there is no agreed-upon definition of service innovation, its impact on society and firms has been considered to be generally significant. To date, many researches have been conducted on service innovation or service-based strategies for firms, but relative to the many discussions on firm-layer service innovation, there are few on the relationship between service innovation and country-specific economic policy. © 2015 IEEE.

Organization and place for partnership of local society and experts is called urban design center. Architecture and planning schools have its examples. This paper reports the first year of Urban Design Center Tamura (UDCT) to show how local government, local community and university collaborate to revitalize a small city. Source
