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 (July 2023) received from the Institute of Comparative Culture, Sophia University; the National Institute for Japanese Literature ; 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 (課題番号：22K00863)（分担者); and JSPS Research Grant (基盤研究C): 18世紀後半における儒学受容の研究―〈家〉を中心に (課題番号 23K00099) (分担者）
