Retirement Remarks

9I retired as the president and CEO of JANSI at the general assembly meeting in June. My successor is Mr. Isao Kato, former CNO of Tohoku Electric Power
Company. I appreciate your support and advice over the years.
I joined JANSI in February 2016 and I steered daily businesses as president and CEO under Chairman Webster for 6 years from 2018. At the time when I came,
JANSI was still in the early days and lacked sufficient experience. The concept of the self-regulation of the industry was not widely understood. Common
understanding has been gradually developed after extensive and thorough discussions among JANSI and utilities about the desired end state of self-regulation.
A 10-year strategy was formulated in fiscal year 2018 under the leadership of Chairman Webster. This strategy has clarified what the industry and JANSI want toachieve and what JANSI needs to do. Each department of JANSI enhanced its program, which was gradually recognized by the industry. Especially, in October 2022
WANO main governing board, for the first time in the world, approved the equivalency of JANSI’s plant peer review to the program of WANO in the light of the world
standards. This increased recognition of JANSI in Japan and abroad.
Attitude of nuclear operators has also greatly changed. They proactively joined in JANSI’s activities and made use of the result for their own improvement.
We revised the 10-year strategy in fiscal 2023, considering progress of our activities and changes of business environment, to make our self-regulation more robustand effective. We set a high future vision “Operators achieve the highest level of safety and reliability, and maintain and sustain that status” and “JANSI becomes aworld-class excellence authority.”
I sincerely hope that JANSI, under the leadership of Chairman Webster and new president Kato, the industry and JANSI make a further leap forward and receive
respect and trust in Japan and the world.
Thank you again for your support over the years and I wish you all the very best.
June 13, 2024
Hiromi Yamazaki
