The global and Japanese energy sectors are in a state of flux, shaped by rapid technological advancements, evolving regulations, and shifting consumer demands. For Idemitsu Kosan, these changes present a complex mix of challenges and opportunities, influencing its Idemitsu Kosan market position.

A significant industry trend is the accelerated drive towards decarbonization and carbon neutrality, with Japan targeting carbon neutrality by 2050. This ambition fuels a substantial increase in renewable energy adoption, particularly solar power, which is projected to grow from 76.70 GW in FY2024 to 79.81 GW in FY2025. The Japanese government's Seventh Strategic Energy Plan underscores rising electricity demand and the critical need for energy security, setting a target for renewable energy to constitute 36-38% of the electricity mix by 2030. This trajectory poses a direct challenge to Idemitsu Kosan's established fossil fuel operations, as domestic oil demand is anticipated to decline by 30% by 2030, 60% by 2040, and 80% by 2050, relative to 2019 levels. The company has already initiated measures to reduce its refinery capacity, exemplified by the termination of refining operations at Seibu Oil's Yamaguchi plant by March 2024, a move that decreased its domestic capacity by 13%. Furthermore, financial headwinds are present, with the CFO of Idemitsu Kosan indicating in May 2025 that US tariffs are expected to impact profits by ¥40 billion in FY2025/26.

Industry Trends: Decarbonization and Renewable Energy Growth

The energy sector is rapidly shifting towards sustainability, with a strong emphasis on decarbonization. Japan's commitment to carbon neutrality by 2050 is a key driver for this transformation.

Challenges from Declining Fossil Fuel Demand

Traditional fossil fuel businesses face significant headwinds due to projected decreases in oil demand. This necessitates strategic adjustments and diversification for companies like Idemitsu Kosan.

Opportunities in New Energy Solutions

The energy transition opens avenues for growth in carbon-neutral fuels and related technologies. Investments in renewables and advanced materials are crucial for future success.

Government Support for Emerging Sectors

Government initiatives, such as funding for hydrogen supply chains, create significant opportunities. These policies aim to foster the development of new, cleaner energy sources.

Strategic Diversification and Future Outlook

These evolving industry trends present substantial opportunities for Idemitsu Kosan to diversify its business portfolio and capitalize on the energy transition. The company is actively investing in carbon-neutral fuels and solutions, including geothermal, solar, and wind power. Its development of advanced battery materials, such as lithium sulphide for solid-state batteries, is a forward-looking strategy. The agrivoltaics project addresses land constraints for solar installations while creating new revenue streams for agricultural communities. Furthermore, the increasing electricity demand in Japan, driven by sectors like AI data centers and semiconductor manufacturing, offers opportunities in power generation and infrastructure development. The government's planned ¥3 trillion investment in hydrogen supply chain development, including a cost-difference mechanism for low-carbon hydrogen, signals significant potential in this nascent sector.
