Nagoya (, Nagoya-shi) is the third-largest incorporated city and the fourth most populous urban area in Japan. Located on the Pacific coast in the Chbu region on central Honshu, it is the capital of Aichi Prefecture and is one of Japan's major ports along with those of Tokyo, Osaka, Kobe, Yokohama, Chiba, and Moji. It is also the center of Japan's third largest metropolitan region, known as the Chky Metropolitan Area. As of 2000, Chky Metropolitan Area has 8.74 million people, of which 2.17 million live in the city of Nagoya. The city's name was historically written as or (both read as Nagoya). One possible etymology for the city's name is the adjective (nagoyaka), meaning 'peaceful'.
