“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 as well as sexual and gender minority populations from a queer and feminist perspective. In particular, I am interested in (1) the association between sexual orientation and gender identity, and socioeconomic status; (2) the measurement of sexual orientation and gender identity in quantitative research; (3) sexual/gender minorities and social attitudes; and (4) queer and feminist methodologies.

Data Collection Experience
Due to the scarcity of data on sexual orientation and gender identity in Japan, I have engaged in primary data collection for my research and designed multiple, large-scale social surveys. I hold the Certificate of Advanced Social Researcher issued by the Japanese Association for Social Research. Below is a list of the surveys that I have been involved in:
- 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 certified nonprofit organization Nijiiro Diversity)

- Research on the Transformation of Attitudes and Policy toward Sexual Minorities (JSPS KAKENHI Grant Number 18H03652, PI: Kazuya Kawaguchi, $430,300)
Sexual/Gender Minorities and Socioeconomic Inequality
In this project, I examine 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 used the Osaka City Residents’ Survey, one of the few population-based surveys that asks about sexual orientation in Japan, to explore the association between sexual orientation and educational attainment, occupational segregation, and earnings disparities in Japan. The research for this dissertation was partially supported by the Harry Bridges Center for Labor Studies at the University of Washington, Japan Center for Economic Research, and JSPS KAKENHI Grant Number JP16H03709 “Demography of Sexual Orientation and Gender Identity: Building a Foundation for Research in Japan.”

Demography of Sexual Orientation and Gender Identity
I am involved in the research project “Constructing a Demography of Sexual Orientation and Gender and Identity: Nationwide Random Sampling Survey” to examine how to quantitatively understand sexual and gender minority populations, while taking the Japanese context into account. I am also interested in describing the diversity of sexual orientation from a demographic perspective.

Attitudes toward Sexual/Gender Minorities
Originally started as senior thesis research on attitudes toward same-sex sexual relations, this project investigates the factors associated with attitudes toward sexual/gender minorities in Japan, with a focus on the Buddhist faith.

Quantitative Queer Methodology
In this project, I explore the possibility of using quantitative methods from a queer perspective. Drawing from emerging literature on queer approaches to quantitative data collection and 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. Between March 2017 and March 2022, I also worked at the Center for Evaluation & Research for STEM Equity at the University of Washington as a graduate 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.
