Editorial policy

To help our stakeholders gain a deeper understanding of the Idemitsu Group's management and overall corporate activities, we disseminate information through the "Idemitsu Integrated Report," the "Idemitsu ESG Data Collection," and the "Sustainability Page" on our official corporate website. We strive to communicate our commitment to sustainable value creation in an easy-to-understand manner.
This website provides information on a wide range of topics from environmental, social, and governance perspectives. We also provide timely updates on our achievements and initiatives.

As a general rule, this report covers our company and all 262 companies in our group as of the end of June 2026. However, if the target group differs, this will be noted.

This report covers the achievements for fiscal year 2025 (April 1, 2025 - March 31, 2026). If the target period differs, this is indicated. Additionally, some activities from April 2026 onwards are also included.

Plans, forecasts, and management targets published on this website that are not historical facts are based on our judgments and assumptions using information available at this time. Please be aware that actual results may differ significantly from forecasts due to various factors. Factors that may affect results include, but are not limited to, economic conditions, crude oil prices, supply and demand trends and market conditions for petroleum products, and exchange rates.
