Large area around Fukushima has been contaminated by radioactive materials due to the nuclear accident after the Great East-Japan earthquake and tsunami. Release from the damaged reactors has almost ceased, and the cleanup of the contaminated land and return of the evacuees are becoming the issues of greatest concern. While the annual dose of 1 mSv is regarded as a goal of cleanup or criterion for return publicly, it is not realistic to lower the doses to that level in the whole area. The goal is also unreasonable considering a true picture of radiation risks. The current situation is more or less attributed to a failure in risk communication. Establishing risk governance, particularly involving people as a stakeholder will be a key for the better solution.
