I studied English Literature as an undergraduate at Sophia University, where I also completed an MA, with a thesis in experimental phonetics. For a second MA, I researched plays by Harold Pinter in the School of Theatre Studies at the University of Warwick. My PhD, also awarded by Warwick, focused on the meeting point of performance, theatre, and improvisation in the contexts of twentieth-century Europe and North America. I joined the School of Political Science and Economics at Waseda University in 2001, where I have taught second-year English, courses on drama and literature, and seminars for first- and second-year students. My current research interests lie in twentieth-century English and Irish drama in production, especially, how speech sounds interact with other kinds of sound.
