Necessity of long-term support after disasters: Lessons from disaster-related death criteria after the Fukushima nuclear disaster
As disasters increase in both frequency and complexity, their indirect effects - such as disruptions to medical care, environmental changes, prolonged periods of evacuation, and psychosocial stress - are increasingly recognised as critical public health issues. In Japan, disaster-related deaths (DRDs) represent an institutional framework to address these secondary health impacts. We compare two DRD certification systems: the Nagaoka Criteria and …
Long-term evacuation and obesity: A 12-year follow-up comparative study of residents inside and outside Katsurao Village after the Fukushima nuclear disaster
Objective: Evacuation, owing to a disaster, impacts various aspects of an individual's life, including health status. This study aimed to determine the prevalence of obesity among residents of Katsurao Village, Fukushima Prefecture, after the evacuation order due to the Fukushima nuclear disaster in 2011 was lifted in 2016 and to compare the prevalence of obesity by place of residence (inside or outside the village). Methods: The number of examin…
Disaster-related deaths with alcohol-related diseases after the Fukushima Daiichi nuclear power plant accident: Case series
Introduction: The health of patients with mental disorders, such as alcohol-related diseases, often deteriorates after disasters. However, the causes of death among those with alcohol-related diseases during and after radiation disasters remain unclear. Methods: To minimize and prevent alcohol-related deaths in future radiation disasters, we analyzed and summarized six cases of alcohol-related deaths in Minamisoma City, a municipality near the Fu…
Case Report: Difficulties faced by a home oxygen therapy patient who died after the Fukushima Daiichi nuclear power plant accident
Following the Great East Japan Earthquake (GEJE) and the Fukushima Daiichi nuclear power plant accident in 2011, mandatory evacuation orders were issued to residents living near the nuclear power plant in Fukushima prefecture, including some patients receiving home oxygen therapy. Although the vulnerability of patients with home oxygen therapy (one of the population groups most vulnerable to disasters) has been noted, there is little information …
Group of longitudinal adverse event patterns after the fourth dose of Covid-19 vaccination with a latent class analysis
Introduction Vaccination has been implemented as a useful measure to combat the COVID-19 pandemic. However, there is a tendency for individuals to avoid vaccination due to the possibility of adverse events, making it important to investigate the relationship between COVID-19 vaccines and their adverse events. This study explored longitudinal adverse event patterns and factors that influence adverse events following the second to fourth doses of t…

Association between the deaths indirectly caused by the Fukushima Daiichi nuclear power plant accident (disaster-related deaths) and pre-disaster long-term care certificate level: A retrospective obse…
The health of the vulnerable populations receiving the Long-Term Care (LTC) Insurance Programs was threatened by the direct and indirect effects of disasters. The 2011 Great East Japan Earthquake and Tsunami and the explosion at the Fukushima Daiichi nuclear power plant (FDNPP) forced 164,865 people's evacuation and caused many disaster-related deaths. We examined the relationship between these deaths and LTC certification. Data were collected fr…
Why Do They Not Come Home? Three Cases of Fukushima Nuclear Accident Evacuees

Surviving in Power: Japanese Prime Ministers and the 1994 Electoral Reform
How does the 1994 electoral reform affect the rapid turnover of Japanese prime ministers in recent years? This article explores possible ways that the electoral reform affects the duration of Japanese leadership tenure and empirically assesses three hypotheses regarding this effect. Statistical analysis from the late 1960s to the end of the 2000s suggests that the effect of the reform depends on a prime minister's popularity. The institutional st…

Decreased thrombin activity by a Congolese herbal medicine used in sickle cell anemia
The Logic of Japan's Free Trade Agreements (FTA) with Asean
Among political scientists, Japan's free trade agreements (FTA) with member nations of the Association of Southeast Asian Nations (ASEAN) has been considered to be a political tool that can compete against China for regional leadership in East Asia. However, this paper demonstrates that Japan's so-called FTA diplomacy towards ASEAN nations serves the broad interests of Japanese actors in both the political and economic sectors.
