Trained as a cultural anthropologist, Inoue has been conducting fieldwork-based ethnographic projects on several fronts. For instance, he has been exploring U.S. military base issues in Okinawa (Japan's southernmost prefecture) ethnographically and historically over the years. His second book on this subject was published in February 2025 https://press.umich.edu/Books/T/The-Community-of-Nuchi-Du-Takara-Life-Is-the-Ultimate-Treasure-in-Postwar-Okinawa2. He has also carried out fieldwork-based ethnographic research about campus policing in the United States. Furthermore, Inoue is prepared for launching a new ethnographic project on the Orthodox Church in Japan. He has taught a wide range of courses, including Japanese language courses, Japanese cultural studies courses, fieldwork-based ethnographic writing courses, and a connected course for the International Village Living Learning Program of which he has served as faculty director since Fall 2020.
