The term itself came into vogue after World War II to describe books and articles that aim to analyze, explain, or divagate on the putative peculiarities of Japanese culture and mentality, above all by comparison with foreign countries, especially Europe and the United States. However Asian countries increasingly figure in recent works. Such texts share a general vision of what constitutes the uniqueness of Japan, and the term nihonjinron can be employed to refer to this outlook. One may also speak of books written by non-Japanese authors as nihonjinron, insofar as they share, contribute to, or reflect the vision, premises, and perspectives characteristic of the Japanese genre.
