Integrated Annual Reports

Latest Version

The “Integrated Report 2026” aims to share our “growth story” toward realizing the Group‘s vision from a medium- to long-term perspective. In the main section, we convey the objectives and background (the “why”) of our strategies, as well as the actions we envision for the future (the “how”), from both financial and non-financial perspectives, details that cannot be fully covered by our IR materials and Annual Securities Reports alone. Furthermore, our specific sustainability activities and their impacts are comprehensively detailed in the the separate volume, “Sustainability Case Studies”. Through this report, we aim to deepen constructive dialogue with our stakeholders, leading to the sustainable enhancement of our corporate value.
Please note that the “Financial and Corporate Data Report” provides comprehensive coverage of our recent business performance and corporate data.
