A Journey Through History
The Opening of the Treaty Port
Yokohama's modern identity began with the opening of its port. By the late 19th century, it had become Japan's most international city. Foreigner areas stretched from the Kannai district to the Bluff area, and the city saw the establishment of a large Chinatown. In 1887, British merchant Samuel Cocking built the city's first official coal power plant, which eventually became the foundation for the Yokohama Cooperative Electric Light Company. The city was officially incorporated on April 1, 1889.

Resilience Through Conflict
The 20th century brought significant challenges to the city. Yokohama was rebuilt following the Great Kantō earthquake of 1923, only to face destruction again during World War II. The city suffered devastating U.S. air raids, most notably the Great Yokohama Air Raid on May 29, 1945. In just over an hour, B-29 bombers reduced 42% of the city to rubble, resulting in an estimated 7,000 to 8,000 deaths.

Postwar Growth and Modern Development
In the decades following the war, Yokohama transformed into a modern metropolis. The city has hosted major international events, including the 2002 FIFA World Cup final and the 2010 Asia-Pacific Economic Cooperation (APEC) meeting. A centerpiece of this modern era is Minato Mirai 21, a massive redevelopment project that transformed former shipyards, wharves, and railyards into a futuristic skyline.

Geography and Climate
Yokohama covers a total area of 437.38 km². Because the city is surrounded by hills and the mountain systems of Honshū, its physical growth has been constrained, forcing much of its expansion to occur by reclaiming land from the sea. This geographic reality contributes to its high population density, which exceeds 8,500 inhabitants per km².

The city experiences a temperate climate. Summers can be quite warm, with record highs reaching 38.1°C (100.6°F), while winters are relatively mild, though occasional snow occurs. The area receives an average annual precipitation of approximately 1,730.8 mm.
