Research themes:
He is engaged in research on diplomatic missions dispatched from the Joseon dynasty (1392-1897) to the Ming dynasty (1368-1644) and the Qing dynasty (1636-1912). He is particularly interested in the historical meaning of transformation of roles and systems of the Joseon missions to the Chinese dynasties under the fluctuating order of East Asia in the 17th century, such as Japanese invasions of Joseon led by Toyotomi Hideyoshi and the Ming-Qing transition, as well as how the Joseon dynasty government recognized and responded to the situations. As these issues are important themes dating back to the earliest studies of oriental history in Japan, he even attempts to reconsider Asian historiography based on the findings obtained.
