We are a transnational and multidisciplinary research project of the Institute of Comparative Culture at Sophia University in Tokyo. Our purpose is to study the global spread of the Japanese restaurant, based on interview and archival data. Our multicultural team has extensive personal and fieldwork experience in Asia, North America, Europe, and Latin America, the world regions where the vast majority of the world’s Japanese restaurants outside Japan are located. Supported by a team of research assistants from Sophia and other universities, we have been interviewing restaurant owners, chefs, and customers in Japanese restaurants in all of these regions. Our goal is to produce a book on Japanese culinary mobilities. We also plan to introduce our preliminary results on this webpage. We are supported by the Sophia University Research Organization and the Sophia University Institute of Comparative Culture.
