We actively use the Integrated Report as a typical Communication tool with all of ourstakeholders. The Integrated Report Production Committee (Headded by Senior ExecutiveOfficer, Group Finance & Accounting office and CFO, and approximately 20 members),
which is organized across divisions, plays a central role in writing and editing the Reportin cooperation with each of the Group's regional operating companies. The Integrated
Report prepared in this way is disseminated and explained both internally and externally.
For internal stakeholders, we introduce it through town hall meetings by top management,
introductory video, internal newsletter and at internal training sessions hosted by theHuman Resources Division. For external stakeholders, we voluntarily conduct feedback
interviews with more than 10 Japanese & non-Japanese institutional investors and1

conduct reader surveys on our website. From the comments we obtained by theseactivities we are implementing an improvement cycle to utilize such information inproduction for the following year and beyond.
We are sharing comments, learned perspectives, suggestions obtained through such
communication with all stakeholders including shareholders and investors, and discusswith the heads of each operation as well as the management to reflect such information
to our daily operations.
The President CEO has served as the main speaker and Q&A session for quarterly
Earnings calls since April 2022, and the Senior Executive Officer, Sustainability
Management Office, and CSO has served as the speaker at the Web IR Conference on
Sustainability initiatives since December 2022. We are making every effort to establish
regular communication contact with the capital market.
Through such activities, we have strengthened the unity within the group, and our stanceof constructive dialogue with all stakeholders has been well received by both the applicant
companies and the judges, which led us to this award.
