power generation between them. One is the area of center station of Kawasaki, and it drives cluster
energy management system with aggregation service of energy management data. The aim of this
area is to achieve effective use of electricity and reduce the amount of the use. The last area around
Musashi‐Kosugi uses data anonymization of private data. Kawasaki city has shared their data via the
66
website "CityData" . They shared the data sets of protection against disasters included places of
shelters, temporary evacuation facilities), meteorology information, disaster prevention
information, such as water stage in a river, rainfall, the place of firehouses, fire prevention water
tanks, population statistics, industry statistics. Moreover, information directly connects to usual life,
such as receptions, garbage separation and collection, and governmental information. Especially in
Musashi‐Kosugi area, Home energy management system (HEMS) is introduced into the houses in
this area and gathers the data from its smart meter to use as localized services by anonymizing with
the data sets. HEMS is a core device to recommend the effective use of electricity to households.
However, the households become tired with the information and come to ignore the information.
Frequent check of the information of HEMS is indispensable to reduce the use of electricity as
self‐action. The specialized HEMS in this area show the information of the data sets and life
information as summarized and customized information to change it into fascinating information.
Moreover, the data captured by a smart meter is gathered and anonymized to use as the watching
services of elder families and persons, door‐to‐door delivery services to optimize their delivery route
by checking the houses' stay, ads and recommendation services, and insurance services for
households.
Kurihara City, Miyagi Prefecture conducts green society ICT life infrastructure project. This project
aims the integration and sophistication of medical, energy, agriculture, climate, local government,
disaster prevention infrastructure, and designs information management system as a cloud service
are designed as the core of this infrastructure. This system utilizes standards and supports several
new smart sustainable city services by providing open interfaces for data analysis and
anonymization. Here, several examples of its application are provided.
This system enables to predict the number of patient of thermic fever in the area by learning the
trend of a number of the patient and weather information and assembling the climate prediction
data. This result enables the city government to predict and prepare required emergency medical
services and number of hospital beds in the future. This result also helps the design of future medical
services. As the application of this data, elder people are likely to catch a thermic fever easily
because they do not feel and think heat. It causes frequent return to the hospitals. Energy
management system and smart agricultural system monitors the temperature, humidity and other
environmental information by embedded sensor networks. In the future, doctors will use these
environmental information to use as a lifestyle recognition and guidance for the elder peoples to
prevent frequent return to the hospitals.
Another application is energy area. The system gets the information that the power consumption
of this area increases by 4% 50 years later.

Hence, applied systems are also proposed. For example, a prediction of data of methodology
prediction and energy demand showed 4% higher after 50 years. Additionally, a prediction of
increasing hot summer days by eight times showed 4% higher demand converges on summer, it
means that electrical power problems would be increased. For the reason of that, demand response
