Yokohama was once just a fishing village, but at the dawn of the Meiji era, it has become a port open to foreign countries and one of Japan's leading commercial hubs. As a result, Japanese goods like copper and raw silk gather in Yokohama for export. At the same time, the city has begun to embrace foreign technology and culture. In the shadows of this development, the merchants of Yokohama make their moves.

In YOKOHAMA, you play as a merchant in the Meiji era, striving to gain fame through successful business. You must develop your trade, expand your sales channels, learn new techniques, and—of course—trade with others.
