10 smart city domestic cases [latest version in 2020]
Technology Smart City DX (Digital Transformation)
(Posted on March 26, 2020)
In recent years, "smart cities" have been attracting attention, and many cities around the world are moving toward realization. This trend is no exception in Japan. Japan is in a situation where it is the first in the world to experience many issues such as the declining birthrate and aging population, but on the other hand, it has the ability to solve problems against the background of high technological capabilities represented by ICT. In various regions, there are movements in which the public and private sectors are working together to realize the future of the city. In this article, I will introduce 10 cases in Japan, why it is necessary to tackle smart cities now, and what kind of efforts are actually being made.
What is a smart city?
Definition of smart city
A smart city is a sustainable city where management (planning, maintenance, management, operation, etc.) is carried out while utilizing new technologies such as ICT to address various issues facing the city, and overall optimization is achieved. Or district, as defined by the Ministry of Land, Infrastructure, Transport and Tourism. The Ministry of Land, Infrastructure, Transport and Tourism plays a leading role in the realization of smart cities in Japan, and the above is defined in the ministry's "Toward the Realization of Smart Cities (Interim Report)" (August 2018).
In addition, Nomura Research Institute defines smart cities as "collecting and integrating various data such as environmental data, equipment operation data, consumer attributes, and behavior data through sensors spread throughout the city, and analyzing them with AI. However, if necessary, we aim to optimize urban infrastructure, facilities, and operational operations, and improve convenience and comfort for companies and consumers by remotely controlling equipment and devices through actuators. " expressing. This is defined in the report "Smart City Report-Overseas Smart Cities as Business Opportunities-" (May 2019) released by the company. Although the definition of smart city, which is a new concept, has not been decided yet, it can be said that it has a common meaning of "sustainable future city" using "various data and ICT technology".
Why smart cities are attracting attention
One of the reasons why smart cities, which are new cities, are attracting attention is the rapid concentration of population in cities. Approximately 50% of the world's population lives in cities, and it is said that the population will increase 1.7 times in 2050 compared to 2010. It is said that energy consumption by cities emits 60% to 70% of greenhouse gases, and it can be said that efficient energy use in urban areas is an urgent task. In addition, the concentration of population in urban areas is a cause of problems such as increased traffic congestion, air pollution, increased crime, and environmental deterioration. On the other hand, Japan is expected to have a labor shortage in the future, and the economic growth so far is expected to decline. Therefore, habitability in the city is more important to secure the labor force. The high environmental load and slowing economic growth associated with these rapid urbanizations are thought to determine the future of society, the environment and the economy, and IoT, sensors, and big data will be used to solve this problem. There are high expectations for smart cities that utilize technologies such as. In other words, it can be said that smart cities are attracting attention as an initiative to solve various problems in urban areas from the present to the future.

Domestic smart city initiatives
Efforts of governments, ministries and local governments

It is positioned as a form of prior realization of "0". Society5.0 is a new society following 1.0 (hunting society), 2.0 (agricultural society), 3.0 (industrial society), and 4.0 (information society), and is a more comfortable society with AI and IoT added to the information society.
