Yokohama

Yokohama is a big port city in Japan, by the sea near Tokyo. It has tall towers, a giant Ferris wheel and a busy harbor.

Yokohama is a port city on Tokyo Bay and the capital of Kanagawa Prefecture, about 30 kilometers from Tokyo. Preliminary results of Japan's 2025 census counted 3,754,840 people there. It grew from a small fishing village after its port opened to world trade in 1859.

Yokohama, capital of Kanagawa and Japan's second city (Universalis), lies on the southwest of Tokyo Bay inside the Tokyo metropolitan area. A modest fishing village when Commodore Perry's ships arrived in 1854, it became one of Japan's first ports open to foreign trade; the 2025 census (preliminary results) counted 3,754,840 residents.

Discover Yokohama

Yokohama is a very big city in Japan. It is by the sea, close to Tokyo.

Millions of people live there, and big ships sail into its port.

Yokohama is the capital of Kanagawa Prefecture, in Japan's Kanto region. Universalis calls it Japan's second city and says it lies about 30 kilometers from Tokyo, on the southwest side of Tokyo Bay.

Preliminary results of Japan's census of 1 October 2025 counted 3,754,840 people in Yokohama, a little fewer than the 3,777,491 counted in 2020.

Census counts on City Population: 3,307,136 (1995), 3,579,628 (2005), 3,724,844 (2015), 3,777,491 (2020) and 3,754,840 (1 October 2025, preliminary), out of 9,193,657 in Kanagawa Prefecture in 2025.

Universalis (Raphaël Languillon-Aussel) says Yokohama is part of the Tokyo metropolitan area and, with the capital and cities such as Chiba, forms a huge built-up region of 33 million people.

Minato Mirai by night

Look at the city lights across the water! There is a very tall tower, and a giant Ferris wheel lit up with colors.

On the right are long red brick buildings.

The photo was taken from Yamashita Park at night on 9 September 2012, looking across the water to the Minato Mirai district. Wikidata's points place three landmarks in that direction: the Yokohama Landmark Tower, 295.8 meters tall, about 1.9 kilometers away; the Cosmo Clock 21 Ferris wheel, 112 meters high, about 1.6 kilometers away; and the Yokohama Red Brick Warehouse, about 0.9 kilometers away.

The tall tower stands at the left, the glowing wheel in the middle and the long red brick buildings at the right.

Wikidata: Yokohama Landmark Tower, a commercial complex and skyscraper, 295.8 m, opened 16 July 1993; Cosmo Clock 21, a Ferris wheel 112 m high with a 100 m diameter (1989); Yokohama Red Brick Warehouse, dated to the 1910s, with an opening date of 12 April 2002.

From Yamashita Park (opened 15 March 1930) the three lie 1.92 km west-northwest, 1.57 km northwest and 0.94 km northwest, matching their order from left to right in the photo.

From fishing village to world port

Long ago, Yokohama was a small fishing village.

Then ships from far away began to come, and it grew into a big port city.

Universalis says Yokohama was only a modest fishing village when Commodore Perry's ships arrived at nearby Kanagawa in 1854. A treaty of 1859 made it one of the very first Japanese ports opened to international trade, and it grew fast.

In 1872 Japan's first railway linked Yokohama with the center of Tokyo, and in 1964 the first section of the Shinkansen, Japan's high-speed railway, strengthened the line.

Universalis describes two halves: the east grew from the port, created from nothing, while the west, around today's central station, grew along the old Tokaido road and then the railway. Kanagawa, the old staging town to the northwest that gave the prefecture its name, was absorbed and became a ward of Yokohama in the 20th century.

Universalis says Yokohama has been twinned with Lyon since 1959, honoring close ties built especially on silk: Yokohama was the country's main outlet for silk and Lyon one of its leading importers.

Through the years

Railways and the waterfront

Japan's very first railway line ran from Yokohama to Tokyo.

Since 1964, fast Shinkansen trains have run on the line too.

Universalis says the railway opened in 1872 was the first in Japan, linking Yokohama with the center of Tokyo, especially the Ginza shopping district. Wikidata dates Yokohama Station to 12 June 1872.

Yamashita Park, on the waterfront, lies about 3.3 kilometers southeast of Yokohama Station, measured in a straight line, and Chinatown is about half a kilometer from the park.

Universalis: the 1872 railway, the country's first, linked the city with central Tokyo (Ginza); the line was reinforced in 1964 by the first national section of the Shinkansen. It explains Yokohama's late growth by the port's distance from the old Tokaido road, made up for by the railway in the late 19th and 20th centuries.

From Yamashita Park (Wikidata points): Yokohama Chinatown 0.47 km southwest, Red Brick Warehouse 0.94 km northwest, Yokohama Station 3.31 km northwest.

About 1,731 millimeters of rain and snow fall in a year. September and October are the wettest months, with about 240 millimeters each, while January and February get about 65. January averages 192.7 hours of sunshine, more than June's 135.9.

Industry, ships and Chinatown

Yokohama has a busy port and many factories. People there have made ships, cars and computers.

It also has a big Chinatown, which has become a place to visit and have fun.

Universalis calls Yokohama one of Japan's main industrial centers. After 1945 came steelmaking, petrochemicals and shipbuilding, then cars in the 1960s and electronics and computing in the 1990s and 2000s. In 2010 the government named it one of Japan's four 'smart communities', testing smart energy networks.

Its Chinatown, where dock and warehouse workers and merchants lived around 1900, is the largest in Japan and has become a place for leisure.

Universalis traces the post-war succession of steel, petrochemicals and shipbuilding (Mitsubishi Heavy Industries, among the city's biggest employers), cars in the 1960s and electronics and computing in the 1990s-2000s, then digital and new-energy technology: in 2010 Yokohama became one of four government-labelled smart communities, with prototypes run by Toshiba.

It calls the city open to the world and twinned with many others, and says its chukagai (Chinatown), once home to dock workers and merchants, is the largest in Japan.
