01 · Overview

Yokohama, in brief

Yokohama is a major municipality situated in Japan, serving as the capital and most populous city in Kanagawa Prefecture. Positioned within the Kantō region of the main island of Honshu, the city lies directly on Tokyo Bay, south of Tokyo.

Geographically and environmentally, the landscape of Yokohama developed from a small fishing village characterized by a distinct sandbar. The original settlement sat upon a sandbar that protruded perpendicularly from the land, or horizontally when viewed from the sea, giving the area its descriptive name. Topographically, the local terrain historically featured low-lying coastal districts alongside elevated areas. The municipality's geography includes coastal waterfront zones along Tokyo Bay, low-lying coastal sectors like Kannai, elevated residential quarters such as the Yamate district, and reclaimed land tracts utilized for industrial expansion and public parks.

The city experiences regional weather patterns typical of the Kantō region and Honshu, subject to seasonal climate shifts, maritime influences from Tokyo Bay, and natural hazards. Throughout its history, the physical environment has experienced significant disruptions from major natural disasters, notably including the Great Kantō earthquake on September 1, 1923, which destroyed much of the city and generated massive amounts of rubble later repurposed for waterfront land reclamation projects such as Yamashita Park.

As a prominent urban center and the nation's most populous municipality, Yokohama functions as a major economic, cultural, and commercial hub within the Greater Tokyo Area and the Keihin Industrial Zone. Its landscape integrates high-tech industrial complexes, major port facilities, and notable urban landmarks including Minato Mirai 21, Yokohama Marine Tower, and Ōsanbashi Pier, while maintaining its identity as a historic cosmopolitan port city connected to the wider geography of international maritime trade.
