The Japanese–Portuguese dictionary "Nippo Jisho" (1603) was the first dictionary of Japanese in a European language, a product of Jesuit missionary activity in Japan. Building on the work of earlier Portuguese missionaries, the "Dictionarium Anamiticum, Lusitanum et Latinum" (Annamite–Portuguese–Latin dictionary) of Alexandre de Rhodes (1651) introduced the modern orthography of Vietnamese, which is based on the orthography of 17th-century Portuguese. The Romanization of Chinese was also influenced by the Portuguese language (among others), particularly regarding Chinese surnames; one example is "Mei". During 1583–88 Italian Jesuits Michele Ruggieri and Matteo Ricci created a Portuguese–Chinese dictionary – the first ever European–Chinese dictionary.
