Japan Power Rental Market - Outlook and Forecast 2023-2029

Market Overview

The Japan power rental market had a value of USD 206.1 million in 2022, and it is projected to reach USD 263.8 million by 2029, growing at a CAGR of 3.59%. The market is driven by several key factors. Firstly, there is a lack of proper grid infrastructure across all regions of Japan, leading to a demand for alternative power solutions. Additionally, the region experiences regular power outages, further driving the need for power rental services. The growing number of infrastructure development projects, such as road and rail expansion and airport network expansion, has also increased the demand for consistent and uninterrupted power supply. Moreover, the construction of hotels and shopping malls in the region has positively influenced the growth of the power rental industry.

The government’s focus on natural disaster prevention measures and infrastructure development has also boosted the power equipment rental market in Japan. The government launched a five-year plan in 2021 with a budget of USD 117.2 billion to accelerate emergency measures for national resilience and disaster prevention. This has prompted an increase in demand for power equipment. Furthermore, Japan is prone to frequent natural disasters like earthquakes, storms, and floods. To ensure access to power during such events, power equipment rental is essential in disaster-prone areas. For example, after an earthquake hit Tokyo in March 2022, the Ministry of Economy, Trade and Industry (METI) issued a Power Crunch alert, highlighting the importance of power equipment in such situations.

Specifically, the Tohoku region experienced significant power outages due to an earthquake, emphasizing the need for backup power equipment. With high energy prices and increased earthquake risks, the region finds it more cost-effective and reliable to rent power equipment rather than purchasing it outright. These factors contribute to the growing demand for power rental equipment in Japan.

In terms of renewable energy, Amazon has partnered with Japanese trading business Itochu to purchase green energy from Clean Energy Connect. Itochu will establish renewable energy supply networks in America and Japan, and a significant corporate power purchase agreement (CPPA) has been signed with Clean Energy Connect to supply Amazon with renewable energy for 20 years. This collaboration will lead to the development of numerous solar power installations in Japan by 2024, generating approximately 38,000 kilowatts of green energy. This represents one of the largest CPPAs in Japan and supports the country’s efforts toward sustainable energy development.

In the retail electricity sector, there is a diverse range of players, including former general electricity utilities, telecommunications carriers, trading companies, gas and petroleum companies, steel manufacturers, and subsidiaries of former general electricity utilities. As of August 2021, 730 entities have obtained retail licenses in this sector. In 2020, former general electricity utilities accounted for 81% of the net system energy demand, highlighting their significant presence in the market.

The Japan power rental market is also influenced by various energy projects. For instance, Japan Gold Corp has announced an exploration program for its Japanese mineral rights portfolio, targeting six projects for development in 2023. Additionally, the Hokkaido Yakumo Wind Power Project, with an anticipated capacity of 184.8 MW, is expected to be commissioned by the end of 2023. These projects, along with the construction, installation, and commissioning of wind and nuclear energy projects, contribute to the growth of the power rental market in Japan.

The Japanese government has been actively investing in public infrastructure development, particularly in airports and railway stations. In 2022, it allocated USD 470 million and USD 490 million for the renovation of Kansai International Airport and Shinjuku Station, respectively. The expansion of Kansai International Airport is currently underway and is scheduled to be completed by 2025. Moreover, the government has initiated maintenance and renovation projects for bridges, tunnels, and roads nationwide. With an increasing focus on infrastructure renovation, the demand for power generation equipment rental in the Japan power rental market is expected to rise.

The Shibuya area is also witnessing significant development projects, with eight key office and commercial projects set to be completed between 2023 and 2029. Additionally, the Tokyo station area is planned for launch by 2027, including the completion of Sakura Stage, a 39-story building development, and the opening of commercial buildings by 2024. These projects contribute to the overall growth and demand for power rental services.

Furthermore, the upcoming international event, Expo 2025, has spurred several construction projects in 2023. With the aim of stimulating the Japanese economy after the Tokyo Olympics, the government is investing over USD 2.6 billion in construction projects for Expo 2025.

Market Segmentation

The market is segmented based on various factors, including fuel, power rating, equipment, end-user, application, and geography.

The use of diesel as a fuel is highly preferred and widely adopted in the market due to its high reliability. As a result, the diesel segment is expected to witness the highest incremental growth opportunity in the coming years. This preference for diesel is driven by its superior reliability compared to other fuels. On the other hand, the others segment is gaining popularity due to the increasing use of renewable energy sources for power generation, aiming to promote clean energy practices and reduce carbon emissions.

Following the 2011 Great East Japan Earthquake and the subsequent Fukushima nuclear accident, all nuclear power plants in Japan were shut down. This event led to a surge in demand for natural gas, as the country relies mostly on imports due to limited domestic production. Unlike oil, Japan produces more gas domestically.

The above 1,000 KVA segment remains the most dominant segment, offering the highest incremental growth opportunity. This can be attributed to the high demand for continuous power in industries such as mining, manufacturing, oil & gas, and petroleum refining. These sectors require a significant amount of power, which drives the growth of this segment. Notably, the Tsugaru Strait Tunnel project, with an estimated budget of $7 billion as of December 2022, is a 31-km long tunnel connecting the mainland of Japan to the northern region of Hokkaido. Its development contributes to the incremental growth in this segment.

Generators hold the dominant share in the market as the increased reliance on power and the ongoing energy transition have resulted in a higher demand for backup power generators. The generators segment is expected to witness the highest incremental growth opportunity during the forecast period. This can be attributed to the frequent power outages caused by unpredictable weather patterns across Japan. Extreme weather conditions and climate change make Japan’s infrastructure vulnerable, leading to increased demand for rental equipment during such times.

The construction sector is anticipated to offer significant incremental opportunities due to various infrastructure projects planned by the federal government. Reconstruction and renovation projects following earthquakes, storms, and floods have contributed to the growth of Japan’s construction industry in recent years. For instance, the Minami Ikebukuro Two Chome C Area Type One Urban Redevelopment project in Tokyo involves the construction of twin residential buildings over a 1.51-hectare land, with a gross area of 189,410 square meters. The project commenced in 2022 and is expected to be completed by 2025.

The surge in demand for power generation equipment for industrial applications is expected to drive the growth of the continuous power rental segment. This segment is anticipated to witness the highest incremental growth compared to other segments due to the continuous need to meet power demands and address supply issues. The Abukuma Onshore wind farm project in Fukushima involves the construction of four onshore wind power plants, with a combined capacity of 147 MW. The completion of this project by 2025 will enhance the renewable power generation capacity of the region and contribute to addressing Japan’s power requirements.
