726 ITU‐T's Technical Reports and Specifications 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 website \"CityData\"66. 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 ____________________ 66 Kawasaki City Open Data, Kawasaki City Office, URL: http://citydata.jp/%E7%A5%9E%E5%A5%88%E5%B7%9D%E7%9C%8C/%E5%B7%9D%E5%B4%8E%E5%B8%82 (2014).
