Ronald Toby is a historian of early modern Japan. Professor emeritus at the University of Illinois at Champaign-Urbana, he is most known for his work on the Korean embassies to Edo, and on representation and conception of foreigners in Edo period Japan.
Toby says that his interest in Japan was first sparked by a Beatnik high school teacher who introduced him to Zen Buddhism, the writings of D.T. Suzuki, and other aspects of so-called "Eastern philosophy." Toby went on to study Japanese language and history at Columbia University, graduating in 1965. He traveled to Japan for the first time in the fall of that same year, where he continued his studies at Tokyo Foreign Languages University and Waseda University on a two-year Monbushô (Ministry of Education) scholarship. For two weeks in late July 1966, during his time in Japan, Toby traveled to Korea for his first time, and says his scholarly interest in Korean-Japanese relations stems from this very first visit. He later took up the study of modern Korean, and of kanbun and other forms of pre-modern / early modern Japanese, in order to pursue research into such subjects.
