Tokyo

Tokyo is the capital city of Japan. It is huge, with tall towers and busy trains. On clear days you can see snowy Mount Fuji far away.

Tokyo is the capital of Japan, at the head of Tokyo Bay. It began as the small town of Edo and was renamed Tokyo, the Eastern Capital, in 1868. About 14.3 million people lived in the Tokyo Metropolis in 2022, and Greater Tokyo is Japan's largest city region.

Tokyo, capital of Japan, grew from Edo, seat of the Tokugawa shoguns from 1603, and took its name, meaning Eastern Capital, when the emperor moved there in 1868. The Tokyo Metropolis had about 14.3 million people in 2022; its 23 wards held 9.7 million in 2020 and Greater Tokyo almost 37 million.

Tokyo is the capital city of Japan.

It sits next to a bay on the Pacific Ocean. Millions and millions of people live there. It has tall towers, quiet gardens and very busy trains.

Tokyo is the capital of Japan. It lies on the Pacific coast of Honshu, Japan's biggest island, at the top of Tokyo Bay. Its name means Eastern Capital.

What most people call the city is its 23 wards, or districts, where about 9.7 million people lived in 2020. They are part of a larger area called the Tokyo Metropolis, home to about 14.3 million people in 2022, which also includes mountains to the west and islands far out in the Pacific. With the cities around it, Greater Tokyo is the largest city region in Japan.

Tokyo stands at the head of Tokyo Bay on the Pacific coast of central Honshu, at the southern edge of the Kantō Plain, the largest plain in Japan. Britannica notes that "the city of Tokyo" usually means the 23 wards, which cover 621 km² and had 9,733,276 people in 2020. As an administrative unit, that city ended in 1943, when it was merged into the Tokyo Metropolis, which also takes in rural and mountain districts to the west, the Izu Islands and the Ogasawara (Bonin) Islands some 800 km to the southeast. The Metropolis had about 14.3 million people in 2022.

Tokyo is the core of the Tokyo-Yokohama metropolitan area, with Saitama, Chiba and Kanagawa prefectures: 36,914,176 people in 2020, about one-fourth of Japan's population. It is the country's largest industrial, commercial and financial center and its chief transport hub.

Famous places

Tokyo Skytree is a super tall tower. You can go up high and look down at the city.

Tokyo Tower is red and white. In the middle of the city is a palace with water all around it. Ueno Park has museums, a zoo and pink cherry blossoms.

Tokyo Skytree, opened in 2012, rises 634 meters above the city. The red-and-white Tokyo Tower, about 333 meters tall, opened in 1958. At the heart of the city is the Imperial Palace, the home of Japan's emperor, ringed by stone-walled moats and wide gardens.

Ueno Park holds the Tokyo National Museum, a science museum, a zoo and art museums, and it is the city's most famous place for cherry blossoms. Bright Ginza is a world-famous shopping street, and in Asakusa stands Sensō Temple, one of the oldest places in the city.

The Imperial Palace occupies the grounds of the former Edo Castle, encircled by stone-walled moats and broad gardens; east of it lies Marunouchi, the financial hub, and to the south Kasumigaseki, which with the districts just west of it holds the main national government offices, including the National Diet Building. Tokyo has no single business district: Britannica describes a city of many centers clustered around railway stations, the largest, Shinjuku, being the main retail and entertainment district in Japan.

Tokyo Skytree (634 m) opened on May 22, 2012, and Tokyo Tower (about 333 m) on December 23, 1958. Ueno Park contains the Tokyo National Museum, with art and history of Japan and Asia, plus a science museum, a zoo and two major art museums. Sensō Temple in Asakusa dates from perhaps the late 7th century, though nearly all its structures were rebuilt after the war. Britannica observes that physically Tokyo is among the newest cities in the world: almost nothing is as much as a century old.

From Edo to Tokyo

Long ago, Tokyo was a small village called Edo.

A powerful ruler made it his home, and it grew very big. Later the emperor moved there. The city got a new name: Tokyo. Tokyo has been rebuilt many times.

Tokyo began as Edo, a village by an inlet of the bay. A small fort was built there in the 1450s. In 1603 the first Tokugawa shogun, a military ruler, made Edo the seat of his government, and it grew so fast that it passed a million people before London or Paris did.

In 1868 the emperor moved here from Kyoto, and Edo was renamed Tokyo. In 1872 Japan's first railroad opened, from Tokyo to Yokohama. The city was badly damaged by an earthquake in 1923 and by bombing in 1945, and both times it was rebuilt. In 1964 Tokyo hosted the first Olympic Games held in Asia.

Tokyo celebrated its 500th anniversary in 1957, counting from the most likely date of the first fortification of Edo, probably little more than a house with log ramparts; the name Edo means something like estuary. Tokugawa Ieyasu took possession in 1590 and in 1603 made Edo the seat of the shogunate, which controlled the country while the imperial court stayed in Kyōto. Much of the marshy Sumida estuary was filled in, and Edo may have become the largest city in the world in the 18th century. Fire was its commonest disaster: the fire of 1657 destroyed about two-thirds of the city.

In 1868 the emperor moved from Kyōto and the city was renamed Tokyo. Japan's first railroad ran to Yokohama in 1872, the year a great fire led to Ginza being rebuilt in brick. The earthquake of September 1, 1923, and the firebombing of March 9 to 10, 1945, both hit hardest in the crowded eastern flatlands. The city was enlarged in 1932, merged with the prefecture in 1943, and in 1964 held the first Asian Olympics. City Hall moved west to Shinjuku in 1991.

Through the years

Getting around Tokyo

Tokyo has lots and lots of trains.

Some run under the ground. Some zoom on bridges above the streets. Super fast bullet trains leave from Tokyo Station. A green train line goes around and around the city.

Trains are the best way around Tokyo. Japan's very first railroad opened between Tokyo and Yokohama in 1872, and Tokyo's first subway line opened on December 30, 1927, between Asakusa and Ueno. Today a thick web of subways and commuter trains covers the city.

The Yamanote Line runs in a loop around the center, and more people pass through Shinjuku Station than through any other station in Japan. High-speed Shinkansen bullet trains leave from Tokyo Station. Most international flights use Narita Airport, about an hour away by train, while Haneda Airport, beside the bay, serves mostly flights within Japan.

The emergence of modern Tokyo coincided with the transport revolution: the first railroad in Japan opened from Tokyo to Yokohama in 1872. The Tokyo Underground Railway Company opened the first subway section, Asakusa to Ueno, on December 30, 1927; it is now part of the Ginza Line. Long-distance trains, including the Shinkansen, leave mainly from Tokyo Station in Marunouchi or Ueno Station; only since 1991 have Shinkansen trains to northern Japan started from Tokyo Station.

The Yamanote Line circles much of the main part of the city, and the busiest centers, Shinjuku, Shibuya and Ikebukuro, lie on its western arc; Britannica writes that more people pass through Shinjuku Station than any other in Japan and quite possibly the world. Commutes can be long, up to four or five hours a day round trip for some office workers. Roads and expressways cannot cope with the traffic, so subways and commuter rail carry most travelers. Narita Airport in Chiba prefecture, opened in 1978, handles most international flights; Haneda, near the Tama River, serves domestic and some international routes.

Weather and seasons

Tokyo has four seasons.

Summer is hot and sticky. Winter is cool and sunny. In spring, pink cherry blossoms open all over the city. In autumn, the leaves turn red and gold.

Tokyo has four clear seasons. August is the warmest month, averaging 26.9 °C, and the air is very humid. January is the coolest, averaging 5.4 °C. It rarely gets much below freezing, and winter is the sunniest season, when you can sometimes see Mount Fuji from tall buildings.

Rainy spells come in early summer and early autumn, and typhoons, the Pacific's name for hurricanes, strike the region in most years. Plum blossoms come first, cherry trees bloom in early April, and May brings azaleas and wisteria.

Japan Meteorological Agency normals for central Tokyo (1991–2020) give a January mean of 5.4 °C, an August mean of 26.9 °C, a yearly mean of 15.8 °C and about 1,598 mm of precipitation a year. Britannica compares the climate with that of Washington, D.C., though Tokyo lies somewhat farther south. Summer is the one really uncomfortable season, with humidity near saturation and August days that reach about 32 °C.

Winter is brisk but rarely falls far below freezing; it is the sunniest season, with the cleanest air, and the only one in which Mount Fuji is often visible from high buildings in the center. Heavy snow usually comes in early spring and melts quickly. Rainy periods arrive in early summer and early autumn, the second linked to typhoons, which strike the region in most years. Plum blossoms come first, cherry blossoms in early April and peonies, azaleas and wisteria in May.

Living in Tokyo

Many people in Tokyo live in apartments.

They ride trains to school and work. On weekends they visit parks, museums and gardens. In spring, families picnic under the cherry blossoms.

Tokyo is a city of many centers. Instead of one downtown, busy hubs with shops, offices and restaurants grow up around train stations, like Shinjuku, Shibuya and Ikebukuro. Between them are quieter neighborhoods of homes and small shops.

Land is very expensive, so many families live in small apartments, and some workers travel a long way to their jobs every day. Tokyo has many parks and gardens, and people visit them to see each season's flowers. The city is also Japan's center for universities, museums and theater, from traditional kabuki to modern plays and concerts.

Early Western visitors described Edo as a collection of villages, and Britannica argues that Tokyo is still best seen as a cluster of cities: satellite centers such as Shinjuku, Shibuya and Ikebukuro, each as large as a city, around their stations. The center of gravity moved west during the 20th century, from the old merchant flatlands by the Sumida River to the hilly High City.

High land prices are among Tokyo's most stubborn problems: families who can afford to live near the center usually have small condominium apartments, and many office workers commute long distances. Parks, temple grounds and gardens are numerous; Ueno Park remains the most famous place for cherry blossoms, and the iris gardens of the Meiji Shrine are celebrated. The University of Tokyo heads a long list of universities, and theaters stage everything from kabuki, which reached great sophistication in Edo, to opera and symphonic music.

Tokyo on the map

Find Tokyo on the globe.

It is in Japan, a country made of islands in Asia. Tokyo is on the biggest island, next to a bay. The Pacific Ocean is close by.

Tokyo is on Honshu, the largest island of Japan, in eastern Asia. It sits at the top of Tokyo Bay, which opens to the Pacific Ocean. Behind it stretches the Kantō Plain, the biggest flat area in Japan.

The city of Yokohama is about 32 kilometers to the southwest, and the cities have grown together into one giant region. Surprisingly, some small Pacific islands about 800 kilometers away are also part of Tokyo.

Tokyo lies at about 35.7° N and 139.7° E, at the head of Tokyo Bay on the Pacific coast of central Honshu. Old Edo occupied alluvial and reclaimed land along and east of the Sumida River and hills to the west; the site was chosen for strategy, commanding the southern approaches to the Kantō Plain. The Tama River forms much of the boundary with Kanagawa, and the Edo River the boundary with Chiba.

Reclamation into the bay has been continuous, and extensive since 1950. Yokohama, Japan's second-largest city, lies about 32 km to the southwest, with the industrial city of Kawasaki between them and Chiba to the east. The Tokyo Metropolis also stretches over the mountains to the west and south along the Izu Islands to the Ogasawara Islands, some 800 km out in the Pacific.
