Cinto Busquet was born on July 30 1961 in Girona (Catalonia), and lived there until the age of 22. He obtained a degree in biochemistry (1984) and a degree in Catalan philology (1985) from the Autonomous University of Barcelona.

After two years in-depth study of the communitarian dimension of Christian experience and faith in the international formation centers of the Focolare Movement at Loppiano (Florence, Italy) and Montet (Fribourg, Switzerland) he went to Japan in May 1987. He spent twelve years living in Tokyo and another five years in Nagasaki. During this period he was particularly involved in interreligious dialogue.

After advanced studies in Japanese at the Nichibei Kaiwa Gakuin in Tokyo, in 1990 he enrolled in the Theological Faculty of Sophia University, Tokyo, where he completed his philosophical and theological studies (1995). For six years up until 1999 he taught at the Faculty of Comparative Culture of the same university. He then moved to Nagasaki in the south-west region of Japan and worked there until 2003. During the period 1993-2002 he was also the director of the monthly publication in Japanese Uno, which follows the same spirit as the magazine Living City and other similar publications of the Focolare Movement.

He was ordained as a Catholic priest in 2001 and since the latter half of 2003 he has been working at the International Center of the Focolare Movement at Rocca di Papa (Rome). Having undertaken specialized studies in the Theology of Religions at the Pontifical Lateran University, his main interest lies in the study of Buddhism and interreligious dialogue between Christianity and the Asian spiritual traditions.
