Japan Balances Energy Security and Green Transition as SMART ENERGY WEEK Highlights Market Shifts

2026/6/22

Japan is increasingly pursuing a dual-track energy strategy that combines stronger energy security with its long-term decarbonization goals, as the country expands renewable energy investment while continuing to restart nuclear power plants.

The shift was reflected at SMART ENERGY WEEK 2026, Japan's largest energy exhibition, where companies across the hydrogen, battery storage, solar, offshore wind and carbon management sectors showcased technologies aimed at supporting the country's evolving energy mix.

The exhibition, held annually in Tokyo, Chiba and Osaka, has become a barometer of policy priorities and commercial activity as Japan seeks to reduce its dependence on imported fossil fuels while advancing its Green Transformation (GX) agenda.

Nuclear and Renewables Positioned as Complementary

Rather than treating nuclear power and renewable energy as competing options, Japan's energy policy increasingly positions them as complementary components of a diversified electricity system.

The government has continued efforts to restart nuclear reactors to strengthen energy security and improve supply stability, while maintaining renewable energy deployment targets to reduce carbon emissions and lower dependence on imported fuels.

At the same time, sectors including offshore wind and hydrogen continue to attract investment supported by Japan's GX framework and transition finance initiatives, with policymakers viewing both industries as strategic drivers of future economic growth.

Floating Offshore Wind Gains Momentum

Offshore wind was among the most prominent themes at WIND EXPO, a specialized exhibition within SMART ENERGY WEEK.

Exhibitors placed greater emphasis on domestic supply chain development and floating offshore wind technology, reflecting growing expectations that Japan's next phase of offshore wind deployment will increasingly focus on floating projects.

"Floating offshore wind is one of the most important sectors for the future," said Norihiro Ogasawara, Executive Show Director of SMART ENERGY WEEK.

Japan's deep coastal waters limit the areas suitable for conventional bottom-fixed wind farms, making floating technology a key enabler for future capacity expansion. Industry participants say growing interest from financial institutions, equipment suppliers and overseas developers could also position Japan as a regional hub for floating offshore wind technologies.

Exhibition Expands Focus Beyond Product Displays

SMART ENERGY WEEK is held three times a year, with spring and autumn editions in Tokyo and Chiba, and a separate exhibition in Osaka.

According to Ogasawara, the frequent schedule is intended to maximize business opportunities rather than simply increase the number of events.

The exhibition focuses on helping exhibitors raise market visibility, meet existing and prospective customers, and generate new business leads.

Organizers say visitor profiles vary across the three events, with participating companies often sending different teams depending on business objectives and technology focus.

The autumn 2026 exhibition is expected to place greater emphasis on emerging sectors including carbon capture, utilization and storage (CCUS) and nuclear fusion, broadening the event's technology portfolio beyond traditional renewable energy.

As Japan's energy transition gathers pace, industry exhibitions are increasingly serving as platforms that connect developers, investors, manufacturers, local governments and technology providers alongside their traditional role as product showcases.

SMART ENERGY WEEK reflects a broader shift in Japan's energy policy away from viewing nuclear power and renewable energy as competing alternatives. Instead, the country's strategy is increasingly centered on building a resilient, diversified energy system that supports energy security while advancing decarbonization.



The exhibition also highlights how policy support, private investment and industrial development are becoming more closely aligned. As Japan accelerates its GX agenda, the technologies and partnerships showcased at SMART ENERGY WEEK are likely to play an increasingly important role in shaping the country's energy transition.
