Japan Energy Efficiency Retrofits Market

Japan Energy Efficiency Retrofits Market Overview:

The Japan energy efficiency retrofits market size is projected to exhibit a growth rate (CAGR) of 7.20% during 2025-2033. At present, rising energy costs are generating awareness about power saving, encouraging more individuals to take action and employ advanced retrofitting systems. Local government agencies are including energy efficiency as a key requirement in urban planning, further supporting retrofitting efforts. Besides this, the growing investments in urban redevelopment projects that require reliable upgrade solutions are contributing to the expansion of the Japan energy efficiency retrofits market share.

Japan Energy Efficiency Retrofits Market Trends:

Increasing energy costs

High energy costs are positively influencing the market in Japan. As energy prices remain high, retrofitting older buildings with efficient systems has become a cost-saving strategy. Japan’s rising population is also catalyzing power demand, making energy efficiency important. As per the worldometers, the estimated population of Japan in 2025 will be 123,103,479 individuals at mid-year. Retrofitting helps lower operational costs by improving insulation, upgrading to light emitting diode (LED) lighting, installing reliable heating, ventilation, and air conditioning (HVAC) systems, and using energy management technologies. These upgrades reduce waste and refine energy performance without requiring complete reconstruction. For businesses, lower energy bills improve profit margins, while residential users benefit from more affordable utility costs. In high-cost energy environments, payback periods for retrofits are shorter, making the investment more attractive. Government support, in the form of rebates and incentives, is adding further motivation. Additionally, high energy costs are generating awareness about energy conservation, leading more people to take action. Retrofitting is especially relevant in Japan, where many buildings are several decades old and were built before modern efficiency standards.

Rising investments in urban redevelopment projects

Increasing investments in urban redevelopment projects are impelling the Japan energy efficiency retrofits market growth. As cities are modernizing infrastructure and renewing old neighborhoods, retrofitting is gaining popularity as a natural part of the redevelopment process. These projects often target aging buildings that were built before energy efficiency became a priority, making them the ideal choice for upgrades. During redevelopment, it is easier and more cost-effective to implement energy-efficient solutions, such as better insulation, advanced lighting systems, smart HVAC units, and energy management systems. Local government agencies are including energy efficiency as a key requirement in urban planning, further supporting retrofitting efforts. Redevelopment also aligns with Japan’s sustainability goals, supporting a transition to greener and smarter cities. In densely populated urban areas, improving the energy performance of buildings reduces the overall environmental footprint and helps manage rising power demands. Property developers and owners are also benefiting, as energy-efficient buildings are gaining traction among tenants and have higher market value. As redevelopment is accelerating in cities like Tokyo and Osaka, the demand for energy efficiency retrofits is growing, making it an essential part of Japan’s urban transformation strategy. In October 2024, construction activities at the ‘Sengakuji Station District Type 2 Urban Redevelopment’ in Tokyo began, following the project's announcement in the first quarter of 2018. The initiative encompassed the building of a 30-story above-ground and three-story below-ground, 145m mixed-use tower, featuring a floor area of 110,644m2 on 1.3ha of land located in Minato-Ku, Tokyo, Japan.

Japan Energy Efficiency Retrofits Market News:

• In January 2025, research was carried out in Japan to assess the effects of insulation materials on energy efficiency through BIM-based simulations for retrofitting existing buildings. The case examined was an apartment complex in Kanazawa, Japan. It was found that the optimal retrofitting scenario was one that resulted in the least energy usage, indicating that the insulation material would exhibit reduced energy usage in comparison to the regional average. This method guaranteed that retrofitting strategies were economically feasible and environmentally sustainable.
• In July 2024, Eneos Renewable Energy planned to incorporate energy storage into an existing solar PV facility in southern Japan, having successfully obtained subsidies to help fund the project. It also aimed to retrofit BESS at the plant. The system was created acknowledging that planning optimal market optimization of BESS assets posed difficulties in the country due to the insufficient connection between platforms for predicting renewable energy generation and electricity demand and those for bidding and transactions.
