The Tokyo Olympic and Paralympic Games (hereinafter referred to as the Tokyo 2020 Games), also known as the “Reconstruction Olympics,” is imminent. Along with this, attention has been drawn from foreign countries regarding the disposal of treated water generated daily at the Fukushima Daiichi Nuclear Power Station and the safety of food produced in Fukushima Prefecture. In particular, while the safety of Fukushima foods has gained the understanding of many foreign countries, unfortunately some of them are not fully understood. Under these circumstances, the Tokyo 2020 Games is expected to play a role in transmitting the form of recovery from the Great East Japan Earthquake and the nuclear accident in Tokyo, the host city, so the Tokyo people will deepen their understanding of the current state of recovery. It is important.
The Mitsubishi Research Institute conducted a questionnaire survey in 2017 focusing on Tokyo residents' awareness, interest, and understanding of the state of reconstruction in Fukushima Prefecture and the health effects of radiation. A second survey was conducted in June 2019, two years after the 2017 survey, to confirm the current state of the Tokyo 2020 Games.

Findings from the survey results

• Although the understanding of the current situation in Fukushima and the health effects of radiation from the accident are improving, no significant improvement has been seen compared to two years ago.
• At the time of the 2019 survey, as in the 2017 survey, about half of Tokyo residents, unlike the latest scientific findings, were concerned about the health effects of radiation on the next generation.
• Contrary to the latest scientific knowledge, continued concern about the health effects of the next generation could lead to discrimination and prejudice in some parts of the country.

Recommendations based on survey results

• It will become even more important in the future to respond from a global perspective that the lack of understanding of the health effects of radiation in Japan will hinder the promotion of understanding overseas.
• It is necessary to avoid suffering from suffering from the problems of discrimination and prejudice, and it is necessary to continue to actively and steadily promote policies that promote understanding of the health effects of radiation.
• As the preparations for the Tokyo 2020 Games accelerate, the importance of the reconstruction Olympics for the domestic and international communities will be renewed without losing interest in the disaster throughout Japan, taking into account Japan's situation. It is necessary to recognize the importance of renewing and understanding the restoration and reconstruction of the affected areas.
