Yokohama lies on Tokyo Bay in the Kanto region and is the second most populated city in Japan after Tokyo. It's the capital city of Kanagawa Prefecture and serves as a commercial hub of the Greater Tokyo Area. Yokohama is also known as the 'Gateway to Japan', which is mainly because it's one of Japan's principal ports. It's a fast growing city and the dominance of trade and industry is evident by the factories, piers, and warehouses that line the waterfront.
