My interests in Japanese history concentrate on the Tokugawa period (1603-1867).
My main project is the Japan Biographical Database, JBDB. The database is aimed at accumulating information on historical figures related to Japan. Using a modern JavaScript web application, we have set up a PostgreSQL database based on the database construction of the China Biographical Database (CBDB) to accumulate data and edit its functions. The project is part of the “Project to Build an International Collaborative Research Network for Pre-modern Japanese Texts” (NIJL-NW project). Funding is currently (Jan 2023) received from the Institute of Comparative Culture, Sophia University; the National Institute for Japanese Literature ; and the JSPS Research Grant (基盤研究C): 近世後期の好古・考証研究の源流と展開に関する学際的国際共同研究（分担者).
