YOKOHAMA
TOPOGRAPHY
As described by the locally produced Guide to the Port of Yokohama, the Port of Yokohama is "Surrounded by moderately rolling hills on the north, west and south" and open to the sea on the east. Some of the hills are evident on Figure V-198. High mountains dominate Honshu to the west and northwest of Yokohama (Figure V-200). The mountains of north central Honshu average 5,000 to 10,000 ft (1,524 to 3,048 m) in height and are often called the Japanese Alps. The highest mountain, 12,395 ft (3,778 m) Mount Fuji, is located about 60 nmi west-southwest of Yokohama. Northern and southern Honshu's terrain is less rugged than central Honshu; southern Honshu has no peaks rising over 5,000 ft (1,524 m). The mountainous terrain of Honshu has a major influence on Yokohama's weather.
