In English, the modern official title of the country is simply "Japan", one of the few countries to have no "long form" name. The official Japanese-language name is "Nippon-koku" or "Nihon-koku" (), literally ""State of Japan"". From the Meiji Restoration until the end of World War II, the full title of Japan was the "Empire of Greater Japan" ( "Dai Nippon Teikoku"). A more poetic rendering of the name of Japan during this period was "Empire of the Sun." The official name of the nation was changed after the adoption of the post-war constitution; the title "State of Japan" is sometimes used as a colloquial modern-day equivalent. As an adjective, the term "Dai-Nippon" remains popular with Japanese governmental, commercial, or social organizations whose reach extend beyond Japan's geographic borders (e.g., Dai Nippon Printing, Dai Nippon Butoku Kai, etc.).
