Yokohama (横浜市 Yokohama-shi ) ( listen (help·info)) is the capital city of Kanagawa Prefecture and the second largest city in Japan by population after Tokyo and most populous municipality of Japan. It lies on Tokyo Bay, south of Tokyo, in the Kantō region of the main island of Honshu. It is a major commercial hub of the Greater Tokyo Area.
Yokohama's population of 3.7 million makes it Japan's largest incorporated city. Yokohama had been the world's largest suburb until the formation of New Taipei (excluding Mainland China as cities there are nonstandard).
Yokohama developed rapidly as Japan's prominent port city following the end of Japan's relative isolation in the mid-19th century, and is today one of its major ports along with Kobe, Osaka, Nagoya, Hakata, Tokyo, and Chiba.
Yokohama was a small fishing village up to the end of the feudal Edo period, when Japan held a policy of national seclusion, having little contact with foreigners. A major turning point in Japanese history happened in 1853–54, when Commodore Matthew Perry arrived just south of Yokohama with a fleet of American warships, demanding that Japan open several ports for commerce, and the Tokugawa shogunate agreed by signing the Treaty of Peace and Amity.
It was initially agreed that one of the ports to be opened to foreign ships would be the bustling town of Kanagawa-juku (in what is now Kanagawa Ward) on the Tōkaidō, a strategic highway that linked Edo to Kyoto and Osaka. However, the Tokugawa shogunate decided that Kanagawa-juku was too close to the Tōkaidō for comfort, and port facilities were instead built across the inlet in the sleepy fishing village of Yokohama. The Port of Yokohama was opened on 2 June 1859.
Yokohama quickly became the base of foreign trade in Japan. Japan's first English language newspaper, the Japan Herald, was first published there in 1861. Foreigners occupied a district of the city called "Kannai" (関内, "inside the barrier"), which was surrounded by a moat, and were protected by their extraterritorial status both within and outside the moat. Many individuals crossed the moat, causing a number of problems. The Namamugi Incident, one of the events that preceded the downfall of the shogunate, took place in what is now Tsurumi Ward in 1862; Ernest Satow described it in A Diplomat in Japan. In 1865 the first ice cream and first beer in Japan were manufactured in the city. Chinese immigrants came to Yokohama in increasing numbers.
After the Meiji Restoration of 1868, the port was developed for trading silk, the main trading partner being Great Britain. Many Western influences first reached Japan in Yokohama, including Japan's first daily newspaper (1870) and first gas-powered street lamps (1872). Japan's first railway was constructed in the same year to connect Yokohama to Shinagawa and Shinbashi in Tokyo. In the same year, Jules Verne set Yokohama, which he had never visited, in an episode of his widely read Around the World in Eighty Days, capturing the atmosphere of a fast-developing, Western-oriented Japanese city.
In 1887, a British merchant, Samuel Cocking, built the city's first power plant. At first for his own use, this coal-burning plant became the basis for the Yokohama Cooperative Electric Light Company. The city was officially incorporated on April 1, 1889. By the time the extraterritoriality of foreigner areas was abolished in 1899, Yokohama was the most international city in Japan, with foreigner areas stretching from Kannai to the Bluff area and the large Yokohama Chinatown.
The early 20th century was marked by rapid growth of industry. Entrepreneurs built factories along reclaimed land to the north of the city toward Kawasaki, which eventually grew to be the Keihin Industrial Area. The growth of Japanese industry brought affluence, and many wealthy trading families constructed sprawling residences there, while the rapid influx of population from Japan and Korea also led to the formation of Kojiki-Yato, then the largest slum in Japan.
Much of Yokohama was destroyed on 1 September 1923 by the Great Kantō earthquake. The Yokohama police reported casualties at 30,771 dead and 47,908 injured, out of a pre-earthquake population of 434,170. Fuelled by rumours of rebellion and sabotage, vigilante mobs thereupon murdered many Koreans in the Kojiki-yato slum. Many people believed that Koreans used black magic to cause the earthquake. Martial law was in place until November 19. Rubble from the quake was used to reclaim land for parks, the most famous being the Yamashita Park on the waterfront which opened in 1930.
Yokohama was rebuilt, only to be destroyed again by thirty-odd U.S. air raids during World War II. An estimated seven or eight thousand people were killed in a single morning on 29 May 1945 in what is now known as the Great Yokohama Air Raid, when B-29s firebombed the city and in just one hour and nine minutes reduced 42% of it to rubble.
During the American occupation, Yokohama was a major transshipment base for American supplies and personnel, especially during the Korean War. After the occupation, most local U.S. naval activity moved from Yokohama to an American base in nearby Yokosuka.
Construction of Minato Mirai 21 ("Port Future 21"), a major urban development project on reclaimed land, started in 1983. Minato Mirai 21 hosted the Yokohama Exotic Showcase in 1989, which saw the first public operation of maglev trains in Japan and the opening of Cosmo Clock 21, then the tallest Ferris wheel in the world. The 860m-long Yokohama Bay Bridge opened in the same year.
In 1993, Minato Mirai saw the opening of the Yokohama Landmark Tower, the tallest building in Japan.
In 2009, the city marked the 150th anniversary of the opening of the port and the 120th anniversary of the commencement of the City Administration. An early part in the commemoration project incorporated the Fourth Tokyo International Conference on African Development (TICAD IV) which was held in Yokohama in May 2008.
In November, 2010, Yokohama hosted the Asia-Pacific Economic Cooperation (APEC) meeting.

Places of interest 
The historic port area is Kannai. Next to the waterfront Yamashita Park is Yokohama Marine Tower, the tallest inland lighthouse in the world. Further inland lies Yokohama Chinatown, the largest Chinatown in Japan and one of the largest in the world. Nearby is Yokohama Stadium, the Silk Center, and the Yokohama Doll Museum. The Isezakichō and Noge areas offer many colourful shops and bars that, with their restaurants and stores catering to residents from China, Thailand, South Korea, and other countries, have an increasingly international flavour.
The small but fashionable Motomachi shopping area leads up to Yamate, or "The Bluff" as it used to be known, a 19th/early 20th century Westerners' settlement overlooking the harbour, scattered with foreigners' mansions. A foreigners' cemetery and the Harbour View Park (港の見える丘公園, Minato no mieru oka kōen) is in the area. Within the park are a rose garden and the Kanagawa Museum of Modern Literature.
There are various points of interest in the futuristic Minato Mirai 21 harbourside redevelopment. The highlights are the Landmark Tower which was the tallest building in Japan (until surpassed by the Tokyo Skytree), Queen's Square Yokohama (a shopping mall) and the Cosmo Clock 21, which was the tallest Ferris wheel in the world when it was built in 1989 and which also doubles as "the world's biggest clock".
The Shin-Yokohama district, where the Shinkansen station is located, is some distance away from the harbour area, and features the 17,000 capacity Yokohama Arena, the Shin-Yokohama Raumen Museum, and Nissan Stadium, known as the International Stadium Yokohama when it was the setting for the final for the 2002 FIFA World Cup.
Sankei-en is a traditional Japanese-style garden in Naka Ward. Designed by businessman Tomitaro Hara, it contains seventeen old buildings brought from all over Japan, ten of which have been declared Important National Cultural Properties.
Among the attractions are festivals and events.
