It is a capital mistake to theorize before one has data. Insensibly one begins to twist facts to suit theories, instead of theories to suit facts.
—Arthur Conan Doyle, “A Scandal in Bohemia” in The Adventures of Sherlock Holmes


I use quantitative methods to study stratification and inequality based on sexuality and gender from a queer and feminist perspective. In particular, I am interested in (1) the association between sexual orientation and gender identity, and socioeconomic status in Japan, (2) sexual/gender minorities and social attitudes, (3) the measurement of sexual orientation and gender identity in quantitative research, and (4) queer and feminist methodologies.

Data Collection Experience

Due to the scarcity of data on sexual orientation and gender identity in Japan, I generally engage in primary data collection for my research projects and have designed multiple large-scale social surveys in Japan. Below is a list of the surveys that I have been involved in:

  1. the “niji VOICE” surveys (a series of web surveys on LGBT issues and the workplace environment, conducted almost annually from 2014 through 2020 by the nonprofit organization Nijiiro Diversity)
  2. the “Survey on Diversity of Work and Life, and Coexistence among the Residents of Osaka City” (one of the first population-based surveys with questions on sexual orientation and gender identity in Japan, conducted in January-February 2019)
  3. the second “Survey on Ideas about Being Men and Women and Social Attitudes” (one of the first nationally representative surveys with questions on sexual orientation, gender identity, and labor market outcomes in Japan, conducted in June-July 2019)

Sexual/Gender Minorities and Socioeconomic Inequality in Japan

In this project, I am interested in examining inequality in socioeconomic status based on sexual orientation and gender identity in Japan. In my dissertation “Sexuality Stratification in Contemporary Japan: A Study in Sociology,” I aim to develop a sociological theory of what I call “sexuality stratification,” or social stratification based on sexual orientation, that is sensitive to cross-cultural differences through describing the association between sexual orientation and various socioeconomic statuses such as education, occupation, and earnings in Japan. My dissertation research is funded by the Harry Bridges Center for Labor Studies at the University of Washington and the Japan Center for Economic Research.

Attitudes toward Sexual/Gender Minorities and Social Attitudes by Sexual Orientation and Gender Identity

Originally started as senior thesis research, this project investigates the factors associated with attitudes toward sexual/gender minorities in Japan, with a focus on religion. In addition, I am currently interested in studying the impact of sexual/gender minority status on various social attitudes in Japan.

Measurement of Sexual Orientation and Gender Identity in Social Surveys

I am involved in a research project “Demography of Sexual Orientation and Gender Identity: Building a Foundation for Research in Japan” to examine how to quantitatively capture sexual and gender minority populations, while taking the Japanese context into account. I am also interested in delineating the diversity of sexual orientation from a queer perspective.

Quantitative Queer Methodology

In this project, I explore the possibility of using quantitative methods from a queer perspective. Drawing from an emerging literature on queer approaches to quantitative data analysis, this project aims to illustrate how quantitative research may be used to empirically evaluate the claims of queer theory and how queer theory, in turn, may be used to inform quantitative research.

Other Research and Program Evaluation Experience

In addition to the projects mentioned above, I have been involved in various research projects related to gender and sexuality. Since March 2017, I have also worked at the Center for Evaluation & Research for STEM Equity at the University of Washington as a research assistant. My evaluation style centers on the perspective of diversity, equity, and inclusion for a more equitable representation of systemically marginalized populations in science, technology, engineering, and mathematics (STEM) educational fields.
