Nagoya

Nagoya is a big city in central Japan. It has a white castle with golden ornaments on its roof.

Nagoya is Japan's fourth-biggest city, with 2,345,892 people at the 2025 census (preliminary count). It grew up around Nagoya Castle, begun in 1610, on the wide Nobi Plain by Ise Bay, and in the 20th century it became one of Japan's great centers of industry.

Nagoya, capital of Aichi Prefecture (2,345,892 people, 2025 census, preliminary), became a castle town when work on Nagoya Castle began in 1610 and grew as a stop on the Tōkaidō road. A port opened in 1907, and by the early 20th century the Chūkyō region was Japan's third industrial center, specializing in heavy industry and machinery.

Nagoya is a big city in Japan. More than two million people live there.

It sits on a wide, flat plain near the sea.

Nagoya is the capital of Aichi Prefecture, in central Japan. At the 2025 census (preliminary results), 2,345,892 people lived there, making it Japan's fourth-biggest city.

It lies on the Nobi Plain, one of the largest plains in Japan, by Ise Bay. Universalis says Nagoya is the heart of the Chūkyō, Japan's third urban region after Tokyo and Osaka, with about ten million people.

Statistics Bureau of Japan (via City Population): Nagoya City had 2,152,184 people in 1995, 2,215,062 in 2005, 2,295,638 in 2015, 2,332,176 at the 2020 census and 2,345,892 at the 2025 census (preliminary, 1 October 2025), fourth after Tokyo, Yokohama and Osaka.

Universalis (Rémi Scoccimarro): capital of Aichi and the core of a megalopolis reaching into Gifu and Mie prefectures, on the Nobi Plain; together they form the Chūkyō, Japan's third urban region, with about ten million people.

Nagoya Castle

Look at the castle! It has white walls and green roofs, piled up high on a big stone base.

At the very top shine two golden roof ornaments.

This photo shows the keep of Nagoya Castle on 24 July 2008: white walls and layers of green roofs rising above a wall of big fitted stones, with a smaller tower beside it.

The castle's official site says the main tower keep was completed in 1612. It was destroyed in the air raids of 1945 and rebuilt in steel-reinforced concrete after the war. The golden ornaments on top, called kinshachi, were restored in 1959; the taller one is 2.621 meters high, and the scales of both are covered in 18-karat gold.

Nagoya Castle official site: Tokugawa Ieyasu had construction of a new castle at Nagoya begun in 1610; the main keep was completed in 1612; the Hommaru Palace, completed in 1615, was rebuilt from Edo-period plans in 2018; the castle is a Special Historic Site. The keep, rebuilt after the war, is currently closed because of its age and earthquake-resistance concerns. The northern kinshachi is 2.621 m tall and weighs 1,272 kg; the southern one is 2.579 m and 1,215 kg.

From castle town to factory city

Long ago, people built a big castle here. A town grew around it.

Later, Nagoya filled with factories and became a huge city.

One of Nagoya's beginnings was as a stopping place on the Tōkaidō, the old road between Kyoto and Tokyo, Universalis says. In 1610 work began on a new castle, and the people of the nearby town of Kiyosu were moved to the castle site, forming today's city, the castle's official site says.

In the 18th century Nagoya grew to nearly 200,000 people, among them many craftspeople; some already specialized in mechanical dolls called karakuri. A railway arrived in 1886 and an industrial port opened in 1907. Nagoya reached one million people in 1934.

Universalis: one origin of the city was lodging along the Tōkaidō road; it became a castle town on the plain, its castle on a mound barely 20 m high, exposed to the floods of the Nobi Plain, whose diked rivers (the Kiso, the Shōnai) later gave high rice yields. In the Edo period (1603–1868) Nagoya took its final shape when the castle moved to its present site in 1610; it grew along a north–south axis from the castle. In the 18th century it had nearly 200,000 people, many of them craftsmen, with a specialty in karakuri mechanical dolls. After 1868 it grew as an industrial and financial city: the Tokyo–Osaka railway reached it in 1886 and its industrial port opened in 1907; it reached a million people in 1934.

Much of the city was destroyed in the Second World War; its rebuilt center kept a grid, with wide avenues such as Hisaya Ōdōri, about 100 m wide.

Through the years

Trains, a port and an island airport

Trains stop at Nagoya Station. Ships use its port, and planes fly from an airport built on an island in the sea!

Nagoya Station opened on 1 May 1886, Wikidata says, when the Tokyo–Osaka railway reached the city. It lies about 2.3 kilometers southwest of the castle. The industrial port on Ise Bay opened in 1907, Universalis says.

Chubu Centrair International Airport opened on 17 February 2005 on an artificial island in Ise Bay, about 37 kilometers south-southwest of the castle. Wide avenues, such as Hisaya Ōdōri, cross the rebuilt city center.

Universalis: the Tokyo–Osaka railway served Nagoya from 1886 and its industrial port was inaugurated in 1907; open to Ise Bay, the Chūkyō became Japan's third industrial center early in the 20th century.

Wikidata (from Nagoya Castle): Nagoya Station (opened 1886-05-01) 2.26 km SW; Nagoya TV Tower (opened 1954-06-20, 180 m) 1.71 km SSE; Hisaya Ōdōri Park 2.07 km SSE; Port of Nagoya (1907) 17.49 km SSW; Chubu Centrair International Airport (opened 2005-02-17, on an artificial island in Ise Bay) 37.36 km SSW.

Hot, wet summers and mild winters

Nagoya's summers are hot and rainy. Its winters are cool and drier.

The World Meteorological Organization's averages for Nagoya (1991–2020) give August an average high of about 33 °C, the hottest of the year. January highs average about 9 °C, and January lows about 1 °C.

Adding up the monthly averages gives about 1,579 millimeters of precipitation a year, on about 103 days. September is the wettest month, with about 232 millimeters, and January the driest, with about 51.

WMO World Weather Information Service, Nagoya (1991–2020): average highs from 9.3 °C in January to 33.2 °C in August; average lows from 1.1 °C in January to 24.7 °C in August. Precipitation sums to 1,578.9 mm; September (231.6 mm), July (211.4 mm) and June (186.5 mm) are the wettest months, January (50.8 mm) the driest; days with at least 1 mm total 103.2.

Universalis notes that the castle site was exposed to the floods that recur on the Nobi Plain.

Machines, cars and a city of makers

Long ago, Nagoya's craftspeople made moving dolls called karakuri. Later, the Toyota car company grew near the city.

Nagoya has long been a city of makers. In the 18th century its craftspeople were already known for karakuri, mechanical dolls that move by themselves, Universalis says. In the 20th century the region became a center of heavy industry and machine building, and the Toyota group grew in Nagoya's eastern suburbs.

In the rebuilt center, the Nagoya TV Tower, 180 meters tall, opened in 1954 in Hisaya Ōdōri Park, Wikidata says.

Universalis: in the 18th century many of Nagoya's people were craftsmen, already specializing in mechanics with karakuri automaton dolls; from the early 20th century the Chūkyō was Japan's third industrial center, in heavy industry and machine building, helped by the rise of the Toyota group in the eastern suburbs. The Tokugawa family, from the province, long took special care over the city's development.

Wikidata: Nagoya TV Tower, construction begun 1953-07-21, opened 1954-06-20, height 180 m, 1.71 km SSE of the castle; Hisaya Ōdōri Park 2.07 km SSE.
