He devoted his entire life to studying the condition of humans and the encounter of cultures across the globe. He went on his first expeditions in Tibet following Giuseppe Tucci, in 1937 and 1948, an experience that would later give rise to the publication Segreto Tibet (1951). Starting in 1939 he moved to Japan where he remained until 1946, though he returned there on various occasions, even for long periods, and became one of the most authoritative scholars of Japanese culture. Some of his most significant works are dedicated to Japan: Ore Giapponesi (1957) and Japan. Patterns of continuity (1971). A vast and important selection of his photographs was presented in the exhibition and relating catalogue Il Miramondo (1999). His Biblioteca Orientale and photo archive are found in the Gabinetto Vieusseux in Florence.
