日本哲学
From the late 1950s on, Viglielmo also developed an interest in modern Japanese philosophy, introducing to the Western world works by the two principal figures of the Kyoto school, Nishida Kitarō and Tanabe Hajime. Viglielmo was abled to visit Tanabe Hajime at his home in Spring of 1959. His first translation of Nishida, "Zen no kenkyū" ("A Study of Good", 1911) in 1960 was considered instrumental in a deepening of East-West comparative philosophy.
