摘要: In the aftermath of Fukushima nuclear accident, many post-disaster responses undertaken by Japanese government sparked vivid debates and criticisms from civil society.

We argue, contrary, cannot be properly without understanding “real” population – what they consider - nor taking into account existing controversies uncertainties. context, need is not so much but rather participatory assessment where are debated multiple stakeholders actors counter- or independent experts third parties NPOs, collectively than decided single-handedly policymakers affiliated experts.
