Alessandro Valignano
Japanese "Kirishitan ban" (キリシタン版 "Christian publications") refers to the books, grammars, and dictionaries published 1591–1611 by the Jesuit Mission Press. In 1590, the Italian Jesuit missionary Alessandro Valignano brought a movable type printing press to Japan. Compared with contemporary woodblock printing in Japan, Üçerler calls this technological superiority the "First IT Revolution".
