I am a doctoral student at the University of Tokyo. I do research in public health, specifically social epidemiology. My thesis is focused on the suicide gap between urban and rural areas, and the underlying social structure. I am involved in the projects ‘Japan Gerontological Evaluation Study (JAGES)’ and ‘Social determinants of health among individuals with foreign background (SMASH)’. In the future, I am willing to try One Health or One Welfare research, combining human and animal health and well-being, by utilizing my experience as a veterinarian.

Against a backdrop of common structural changes occurring worldwide in the agricultural sector including increasing global competition, a decline in the number of farms, and increasing farm size farmers’ mental health is increasingly becoming a global cause for concern. In Japan, farming is characterized by both a declining and aging farming population. Farmers may suffer from serious health issues and social isolation that might be attributable to a variety of factors including the neighborhood environment. Despite this, until now there has been little research on the mental health of farmers in Japan and the factors associated with it. The aim of this study was to examine whether neighborhood farm density and the type of agriculture are associated with the mental health of farmers in Japan. More specifically, we used data from the Japan Gerontological Evaluation Study to evaluate the cross-level interaction for depressive symptoms between farm density at the neighborhood level and occupation. Results from a Poisson regression analysis showed clear differences in depressive risk among farmers by neighborhood farm density.

International migration is a global phenomenon, and has drawn extensive debate even in inclusive welfare states like Sweden. Immigrants may suffer from serious health issues, attributable to discrimination due to national immigration policies and negative social norms for immigrants in certain residential areas, and the impacts of this discrimination may vary across the places where they live. We therefore focused on rurality as a potential areal context strongly affecting the mental health of immigrants; and, using whole Swedish registry data, we evaluated the effect of its interaction with immigrants’ countries of birth on suicide risk. We found highly interesting results, showing clear differences in suicide risk by gender, areal size when evaluating rurality, and country of birth.

This study focuses on the relationship between occupation, environment, and supports for perinatal parents given the recent rise in inter-prefectural inequality in the under-5 mortality rate in Japan since the 2000s. Using national vital statistics by household occupation between 1999 and 2017, we showed the existence and increasing time trend of inter-occupational inequality in infant mortality. Furthermore, the inequality among household occupation was different according to the regional characteristics. Our findings suggest that, even if Japan has the lowest infant mortality rate in the world for a long time, certain occupations and unemployed increase the risk of infant mortality.

This study builds upon our current knowledge of suicide rates in rural areas by examining possible correlations with the type of agriculture that predominates in each rural area. We have analyzed specific factors that may play a role in the heightened suicide risk in Japan’s rural and specifically agricultural municipalities, allowing researchers and policymakers alike to develop new insights into this phenomenon and potentially develop new interventions to more effectively target at-risk individuals based on compositional and contextual factors.
