Port of Yokohama
Upon the opening of the Port of Yokohama in 1859, Kannai became the commercial center of the foreign settlement and home of international trading companies and diplomatic missions, similar to Dejima in Nagasaki. As the foreign settlement rapidly expanded, further residential areas, churches, a cemetery and schools were added on the nearby elevated Yamate "Bluff" overlooking the harbour. The historic Osanbashi Pier was built adjacent to Kannai in 1894, and has been the international pier of the Port of Yokohama ever since.
