Abstract: As a growing amount of research examines the impact of sexuality on various demographic outcomes, it becomes important to understand the complex intersections of sexual orientation identity, sexual/romantic attraction, and sexual behavior. However, most previous studies use data from Western countries that have particular histories of sexuality, limiting the generalizability of the findings beyond Western societies. We describe dimensions of sexuality in Japan, where there has not been any religious authority condemning same-sex behavior and any law prohibiting same-sex relations except for a decade in the late 19th century. We use data from the “Survey on Diversity of Work and Life, and Coexistence among the Residents of Osaka City,” the first population-based survey with detailed questions about multiple aspects of sexuality in Japan, to conduct descriptive analysis. More women identify as bisexual or asexual than lesbian. Among the respondents who selected “Don’t want to decide, haven’t decided”—a category originally created for queer/questioning respondents—as their sexual orientation, the proportion of those who indicated exclusive heterosexuality is higher than expected, raising the possibility that some heterosexual respondents with no heterosexual identity may have mistakenly chosen this category. The data suggest that the population of heterosexual-identified men who have sex with men is small. The prevalence of the asexual population differs by whether sexual orientation identity or sexual/romantic attraction is used to capture this population. Our analysis extends the demography of sexuality by examining unique non-Western data and putting in context the previous findings observed in Western countries.

Presentations at the 2019 Japan Sociological Society conference

On Sunday, October 6, I presented my paper “Inequality in Socioeconomic Status Based on Sexual Orientation and Gender Identity in Japan: Findings from the Osaka City Residents’ Survey” and my co-author, Saori Kamano, presented our joint work “Asking about Sexual Orientation and Gender Identity in Social Surveys: Case Report on the Osaka City Residents’ Survey and Related Preparatory Studies” at the 92nd Annual Meeting of the Japan Sociological Society held at Tokyo Women’s Christian University.

The slides from these presentations (in Japanese) are available on the project webpage of the National Institute of Population and Social Security Research.

New Discussion Paper Released on the Website of the Japan Institute for Labour Policy and Training

My co-authored discussion paper “An Estimation of Social Loss Due to Suicide and Depression among Sexual/Gender Minorities, and a Survey on Income Disparity between Them and the Non-Minority” has just been published on the website of the Japan Institute for Labour Policy and Training!

Abstract: As part of an attempt to understand the reality of social difficulties including bullying and harassment at the workplace, this study summarized social difficulties among LGBT (lesbian, gay, bisexual, and transgender) people who may be affected by a peculiar kind of harassment related to discrimination, namely SOGI harassment (harassment related to sexual orientation and gender identity), and estimated the social costs associated with it. Estimated social loss due to suicide and depression among LGBT people (provisional) amounted to 1,988-5,521 million dollars (of which 994-4,186 million dollars are due to social difficulties specifically for being LGBT). Also, a survey of previous studies confirmed that, although the income of lesbians is relatively higher than that of heterosexual women and the income of gay men tends to be lower than that of heterosexual men, the income difference varies highly depending on previous studies.



Comprehensive Exam Reading List (Social Stratification)

As six months have been passed since I completed my comps in social stratification, I’m uploading my reading list here, for those who are interested. Please note that this reading list does not necessarily represent the whole field of social stratification. The reading list is tailored to my research interests.
