Message
The Nuclear Regulation Authority of Japan was established as an independent regulatory authority based on lessons learned from the 2011 Fukushima Daiichi nuclear accident. Since that time, we have made tireless efforts to ensure transparency and implement regulatory measures reflecting the latest domestic and international information and lessons.
The Fukushima Daiichi nuclear accident is still fresh in our memory. The NRA has maintained a keen sense of mission and responsibility at the highest levels, but it is also true that, as human beings, we tend to forget things over time. Thus, it is essential to engrave the lessons learned from Fukushima in the NRA’s institutional memory rather than just personal reflections.
We must avoid lapsing into a mind-set of self-satisfaction and recognize that the pursuit of the highest safety standards is our highest, ongoing priority. I am determined to do my best to instill widespread confidence in our nuclear safety regulations based on independence and transparency.

Message
The ultimate purpose of safety regulation is to protect humans. As for radiation safety, it means to protect people from harm of radiation exposure. The experience of Fukushima Daiichi Accident indicates that the issue should not be confined to biological effects to humans, but should be taken from the perspective of people living in the society. I will do my best at every single task, giving due consideration of radiation risks on a scientific basis and keeping human dimension in mind.
