city, Hiroshima ken (prefecture), Honshu, Japan, facing the Inland Sea. The city's port opened in 1168 and served for about 500 years as a rice shipment centre and port of call for trade with China. The port's commercial significance declined somewhat during the Tokugawa era (1603-1867) but has since revived. Onomichi now offers steamship services to ports of northern Shikoku and islands in the Inland Sea. The city has a shipbuilding yard and a motor factory.
