Close to 60% of Japanese municipalities have yet to implement death review systems, as per the news headline. These systems are crucial for examining the circumstances behind unnatural deaths, with goals of prevention and policy improvements. The report does not specify which regions are most affected, but calls out the need for all municipalities to prioritize establishing these systems in order to improve public health response and the overall well-being of the community.

In Japan, the establishment of death review systems is seen as an essential part of health policy. The Japanese public view the lack of these measures as a deficiency in their local government's ability to safeguard their wellbeing. It taps into the deeper societal values of duty, responsibility and the expectation for authorities to provide the highest level of care and protection for the people.

In the US and EU, death review systems are generally well-established and seen as necessary for maintaining public health. In many instances, they form part of the wider public health response and policy development. Their establishment is not usually a contentious issue, as it might be in Japan where a significant proportion of municipalities have yet to implement such mechanisms.
