Shuichi Ishibashi Letter To Accompany The CodeBridgestone’s founder Shojiro Ishibashi had a corporate philosophy that a simple profit-seeking businesswill never thrive, but a business that contributes to its society and country will be forever profitable. His
philosophy has served as a foundation of the Bridgestone Group’s mission of “Serving Society withSuperior Quality”. Bridgestone’s corporate activities that are driven by this mission lead to the success of
the Group as well as each and every one of us today and into the future.

The Code of Conduct, established in 2018, is set as a norm that applies across the entire Group and to help
guide each and all of us to do the right thing and fulfill our mission in our daily business and operations,in conjunction with the Global Anti-Bribery Policy, Global Human Rights Policy, and many other global andregional-specific policies that have been adopted throughout Bridgestone. I have watched as our Codeof Conduct has become part of our Bridgestone culture, our conversations with each other and thoseoutside Bridgestone, and guided our decision making. I want to thank you all for your cooperation.

We are currently living in turbulent times: the COVID-19 pandemic, geopolitical risks associated withchanges in the global balance of power, environmental issues such as climate change, and the many
enormous natural disasters that are said to be caused by such environmental issues, to name just a few.

In these turbulent times, guided by our unwavering mission "Serving Society with Superior Quality", wehave established the new "Bridgestone E8 Commitment" as the axis to drive management while earning
the trust of future generations in March 2022 to realize our vision "Toward 2050, Bridgestone continues
to provide social and customer value as a sustainable solutions company.” issued in 2020.

Based on thisCommitment, we announced the "2030 Long-Term Strategic Aspiration" in August 2022 as a roadmap forour transformation to a resilient and "excellent" Bridgestone that possesses the strength and the flexibility
to transform change to opportunity. Continuing to evolve along this roadmap will enable Bridgestone tocontinue to support the mobility of people and objects as well as fulfill its mission.

For Bridgestone to continue such evolution, we must earn the trust of the future generations by always
acting ethically and with integrity. Our Code of Conduct shall provide us with practical guidance on how
to act accordingly.

1The Code of Conduct has guided the daily actions of all of our teammates since its publication in 2018.
There have been various changes, including the establishment of the Bridgestone E8 Commitment andthe revision of our Global Human Rights Policy, as four years have passed since then. We have now
incorporated these changes in the Code of Conduct and also brushed up some of the content based on
the comments and questions received from our teammates.

I ask all Bridgestone teammates to revisit the updated Code of Conduct and use it wisely in their daily
business. Also, please make good use of the Code not only by its “wording” but also by its “spirit” as wellas Bridgestone’s values of our mission. I would like to remind our leaders, managers and supervisors
around the world that each and every one of you have a particular role to play in actively applying our
Code of Conduct and helping teammates understand and follow the Code in their daily activities.

Finally, I ask that whatever you do at Bridgestone, do it with integrity and let our Code guide you, always.
