Cities designated by government ordinance of Japan in the context of Niigata, Niigata

This is a list of cities in Japan sorted by prefecture and within prefecture by founding date. The list is also sortable by population, area, density and foundation date. Most large cities in Japan are cities designated by government ordinance. Some regionally important cities are designated as core cities. Tokyo is not included on this list, as the City of Tokyo ceased to exist on July 1, 1943. Tokyo now exists as a special metropolis prefecture (都, to), with 23 special wards (with the same status of city) making up the former boundaries of the former city in the eastern half of the prefecture.

A core city (中核市, chūkakushi; Japanese pronunciation: [tɕɯː.ka.kɯ̥ꜜ.ɕi, -kaꜜ.kɯ̥-]) is a class or category of Japanese cities. It is a local administrative division created by the national government. Core cities are delegated many functions normally carried out by prefectural governments, but not as many as designated cities. To become a candidate for core city status, a city must have a population greater than 300,000 and an area greater than 100 square kilometers, although special exceptions may be made by order of the cabinet for cities with populations under 300,000 but over 200,000. After the abolition of special city status on April 1, 2015, any city with a population above 200,000 may apply for core city status.

Application for designation is made by a city with the approval of both the city and prefectural assemblies.

Hokkaido (Japanese: 北海道, Hepburn: Hokkaidō; pronounced [hok.kaꜜi.doː] , lit. 'Northern Sea Circuit'; Ainu: Aynu Mosir, lit. 'Land of the Ainu') is the second-largest and northernmost of Japan's four main islands. Together with its surrounding islands, it comprises the largest and northernmost prefecture, making up its own region. The Tsugaru Strait separates Hokkaidō from Honshu. The two islands are connected by railway via the Seikan Tunnel.

The largest city on Hokkaido is its capital, Sapporo, which is also its only ordinance-designated city. Sakhalin lies about 43 kilometres (27 mi) to the north of Hokkaidō. To the east and northeast are the Kuril Islands, which are administered by Russia. The four most southerly are claimed by Japan. Hokkaido's position on the northern end of the Japanese archipelago results in a colder climate, with the island seeing significant snowfall each winter. Despite the harsher climate, it serves as an agricultural breadbasket for many crops.

Osaka (Japanese: 大阪市, Hepburn: Ōsaka-shi; pronounced [oː.sa.kaꜜ.ɕi]; commonly just 大阪, Ōsaka [oː.sa.ka] ) is a designated city in the Kansai region of Honshu in Japan. It is the capital of and most populous city in Osaka Prefecture, and the third-most populous city in Japan, following the special wards of Tokyo and Yokohama. With an estimated population of 2,816,247 as of October 1, 2025 and a population density of about 12,505 people per square kilometer, it is the largest component of the Keihanshin Metropolitan Area, which is the second-largest metropolitan area in Japan and the 10th-largest urban area in the world with more than 19 million inhabitants.

Osaka was traditionally considered Japan's economic hub. By the Kofun period (300–538) it had developed into an important regional port, and in the 7th and 8th centuries, it served briefly as the imperial capital. Osaka continued to flourish during the Edo period (1603–1867) and became known as a center of Japanese culture. Following the Meiji Restoration, Osaka greatly expanded in size and underwent rapid industrialization. The construction boom accelerated population growth throughout the following decades, and by the 1900s, Osaka was the industrial hub in the Meiji and Taishō eras. Osaka made noted contributions to redevelopment, urban planning and zoning standards in the postwar period, and the city developed rapidly as one of the major financial centers in the Keihanshin Metropolitan Area.

Chiba (千葉市, Chiba-shi; Japanese pronunciation: [tɕiꜜ.ba, tɕi.baꜜ, tɕi.baꜜɕi]) is the capital city of Chiba Prefecture, Japan.

In March 2025, its population was 983,045, with a population density of 3,617 people per km. The city has an area of 271.77 square kilometres (104.93 sq mi).

Chiba City is one of the Kantō region's primary seaports, and is home to Chiba Port, which handles one of the highest volumes of cargo in Japan. Much of the city is residential, although there are many factories and warehouses along the coast. There are several major urban centres in the city, including Makuhari, a prime waterfront business district in which Makuhari Messe is located, and Central Chiba, in which the prefectural government office and the city hall are located.

Sagamihara (相模原市, Sagamihara-shi) is a city in Kanagawa Prefecture, Japan.

The total area of the city is 328.91 square kilometres (126.99 sq mi). Sagamihara is the third-most-populous city in the prefecture, after Yokohama and Kawasaki, and the fifth most populous suburb of the Greater Tokyo Area. Its northern neighbor is Machida, with which a cross-prefectural merger has been proposed.

On April 1, 2010, the city became the 19th city designated by government ordinance. As a result of this, three wards were established: Midori-ku, Chūō-ku and Minami-ku.

Saitama (さいたま市, Saitama-shi; Japanese pronunciation: [saꜜi.ta.ma, sai.ta.maꜜ.ɕi]) is the capital and largest city of Saitama Prefecture, Japan. Its area incorporates the former cities of Urawa, Ōmiya, Yono and Iwatsuki. It is a city designated by government ordinance.

Its total area is 217.43 square kilometres (83.95 sq mi).

Sapporo (札幌市, Sapporo-shi; [sap.po.ɾo, sap.po.ɾoꜜ.ɕi] ) is a designated city in Hokkaido, Japan. Located in the southwest of Hokkaido, it lies within the alluvial fan of the Toyohira River, a tributary of the Ishikari River. Sapporo is the capital of Hokkaido Prefecture and Ishikari Subprefecture. As of July 31, 2023, the city has a population of 1,959,750, making it the largest city in Hokkaido and the largest north of Tokyo. It is the fifth-most populous city in Japan and is Hokkaido's cultural, economic, and political center.

Originally a plain sparsely inhabited by the indigenous Ainu people, the area contained a few trade posts of the Matsumae domain during the Edo period. The city began as an administrative centre with the establishment of the Hokkaido Development Commission headquarters in 1869. Inspired by the ancient cities of Kyoto and Heijō-kyō, it adopted a grid plan and developed around Odori Park. After the Second World War, it replaced Otaru as Hokkaido's commercial and business hub, and its population surpassed one million by 1970.

Hokkaido (Japanese: 北海道, Hepburn: Hokkaidō; pronounced [hok.kaꜜi.doː] , lit. 'Northern Sea Circuit'; Ainu: Aynu Mosir, lit. 'Land of the Ainu') is the second-largest and northernmost of Japan's four main islands. Together with its surrounding islands, it comprises the largest and northernmost prefecture, making up its own region. The Tsugaru Strait separates Hokkaido from Honshu. The two islands are connected by railway via the Seikan Tunnel.

The largest city on Hokkaido is its capital, Sapporo, which is also its only ordinance-designated city. Sakhalin lies about 43 kilometres (27 mi) to the north of Hokkaido. To the east and northeast are the Kuril Islands, which are administered by Russia. The four most southerly are claimed by Japan. Hokkaido's position on the northern end of the Japanese archipelago results in a colder climate, with the island seeing significant snowfall each winter. Despite the harsher climate, it serves as an agricultural breadbasket for many crops.

Fukuoka (福岡市, Fukuoka-shi; [ɸɯ̥.kɯꜜ.o.ka, -kɯ.o.kaꜜ.ɕi] ) is a designated city in the Kyushu region of Japan and the capital city of Fukuoka Prefecture. The city is built along the shores of Hakata Bay, and has been a center of international commerce since ancient times. The area has long been considered the gateway to the country, as it is the nearest point among Japan's main islands to the Asian mainland. Although humans have occupied the area since the Jomon period, some of the earliest settlers of the Yayoi period arrived in the Fukuoka area. The city rose to prominence during the Yamato period, and because of the cross-cultural exposure, and relatively great distance from the social and political centers of Kyoto, Osaka, and later, Edo (Tokyo), Fukuoka gained a distinctive local culture and dialect that has persisted to the present day.

Fukuoka is the most populous city on Kyūshū island, followed by Kitakyushu. It is the largest city and metropolitan area west of Keihanshin. The city was designated by government ordinance on April 1, 1972. Greater Fukuoka, with a population of 2.5 million people (2005 census), is part of the heavily industrialized Fukuoka–Kitakyushu zone.

Kitakyushu (北九州市, Kitakyūshū-shi; Japanese pronunciation: [kʲi̥.ta.kʲɯꜜː.ɕɯː, kʲi̥.ta.kʲɯː.ɕɯꜜː.ɕi]) is a city located in Fukuoka Prefecture, Japan. As of June 1, 2019, Kitakyushu has an estimated population of 940,978, making it the second-largest city in both Fukuoka Prefecture and the island of Kyushu, after the city of Fukuoka. It is one of Japan's 20 designated cities, one of three on Kyushu, and is divided into seven wards.

Sited at the northern tip of Kyushu, Kitakyushu was formed in 1963 from a merger of municipalities centered on the historic city of Kokura, and its name literally means "North Kyushu". It is located on the Kanmon Straits, separating the island from Honshu, across from the city of Shimonoseki in Yamaguchi Prefecture. Kitakyushu and Shimonoseki are connected by numerous transport links including the Kanmon Bridge and the Kanmon Tunnels (Roadway, Railway, and Shin-Kanmon).
