Mitsuko’s research interests centre on Japanese art, with particular emphasis on woodblock prints of the Edo period (1603–1867). She is also fascinated by the art of Kabuki theatre, exploring its change and continuity over time as one of the most significant and enduring forms of Japanese art and cultural expression.
Mitsuko also has an interest in the archaeology and material anthropology of ancient Japan, especially the Jōmon and Kofun periods, with a focus on childhood and the material culture associated with children. In addition, she is interested in the role museums play in shaping representations of culture and identity, particularly how perceptions of Japan and its culture are constructed through literary sources and museum objects.
