Moreover, the acceptance of the latest innovations and technologies and the incorporation of unified platforms for a common service provision and twin technology are transforming Japan’s Smart Cities Market. The country lacks smart experts and professionals for the smooth conduct of smart services in the country. In addition to that, the high initial investments for smart services and product installations in a single city in the country are restraining the market growth.

Japan Smart Cities Market Driver:

Rapid Shift Towards Sustainability & Urban Efficiency   – Japan is witnessing a huge rise in pollution, which is increasing environmental issues and energy wastage. Also, Japan is facing a scarcity of natural resources due to extensive utilization of these. It is further leading to a strong demand for sustainability and urban efficiency in the country. As a result, many new smart cities have been developed in the country in recent years. For instance, Fujisawa Sustainable Smart Town, located near Tokyo, was developed by a company called Panasonic has smart grids, solar panels, and more that aim to achieve 70% CO2 reduction and 30% renewable energy.

Additionally, Kashiwanoha Smart City integrates smart energy supply infrastructures, and the Yokohama Smart City is actively providing Energy Management Systems to almost 4,000 residential units and achieving 20% energy reduction. These developments are increasing the Smart Cities Market in Japan.

Japan Smart Cities Market Opportunity:

Strategic Government Initiatives Boosting Smart City Development – The Japanese government is making efforts to support the growth of this market by implementing policies and significantly investing in the development of smart cities in Japan. The National government is planning to construct 100 smart cities by the end of 2025 with an estimated allocation of about USD8.5 billion, which is creating a huge growth opportunity for this market. Incentives, including Society 5.0, aim to develop a human-centered digital Society by implementing cyber systems in the urban regions of the country. Moreover, the rising collaboration of different ministries, increasing public and pilot projects, and Revitalization 2.0 are targeting the incorporation of IoT-enabled smart systems and are contributing to the potential market growth.

Japan Smart Cities Market Challenge:

High Implementation Costs & Data Privacy Concerns – To transform a city into a smart one requires a substantial amount of funding for the establishment of various systems and devices such as sensors, IoT devices, related platforms, AI-driven products, and more. The heavy investments for the implementation of these services are a major challenge to this market. For instance, the cost to convert a single building into a smart building is about USD 5,000,000. Additionally, a mid-size transformation costs around USD700 million, and a large-size smart city development requires more than 2.5 billion, which is significantly high to put financial barriers forward to this market.

Additionally, rapid digitalization is causing high vulnerability to sensitive informative data from being hacked. Japan has faced many ransomware and malware cyberattacks these days, due to which the market growth is being hindered.

Japan Smart Cities Market Trend:

Rising Adoption of Digital Twins & Unified Data Platforms – The market is gaining popularity due to the widespread acceptance of the latest models, including digital twin systems and the unified data platforms in Japan for the development of smart cities in the country. The very first initiative for the adoption of twin technology in Japan was launched by the Ministry of Land, Infrastructure, Transport, and Tourism (MLIT) in early 2020, called Project PLATEAU. Under this incentive, it provides virtual models of the cities in which the decisions for traffic management, disaster management, etc. are taken based on these virtual 3D models.

Additionally, the Unified Data Platforms help to organize the data and perform deep analysis of this data on a single platform for real-time monitoring of different smart sectors at a time in a city. Several platforms such as FIWARE-Based Platforms, Urban OS, and Tokyo Data Platform (TDPF), are being proactively used in the country.
