Saitama (city)

Geography

The city is located 20 to 30 km north of central Tokyo, roughly at the center of the Kantō Plain. Situated in the southeast of Saitama Prefecture, the city is topographically comprised by lowlands and plateaus, at mostly less than 20 m above sea level, with no mountain ranges or hills within the city boundaries. The western portion of the city lies on the lowland created by the Arakawa River along with those created by small rivers such as the Moto-Arakawa River, Shiba River, and Ayase River. The rest of the area mostly resides on the Ōmiya Plateau lying in the north-south direction. Dispersed in this region, major rivers flow southward, almost paralleling to one another.

Demographics

Per Japanese census data, the population of Saitama has increased steadily over the past century.

Wards

Saitama has ten wards (ku), which were assigned official colors as of April 2005:

History

The city was founded on May 1, 2001, and was designated on April 1, 2003 as a government ordinance. For the histories of Urawa, Ōmiya and Yono before the merger, see:

• Urawa-ku, Saitama
• Ōmiya-ku, Saitama and
• Yono, Saitama, respectively.

On April 1, 2005, Saitama absorbed the city of Iwatsuki to its east, which became a new ward, Iwatsuki-ku. The city evaded the major impact of the 2011 Tōhoku earthquake and tsunami.

Government

Saitama has a mayor-council form of government with a directly elected mayor and a unicameral city council of 64 members. Saitama contributes 14 members to the Saitama Prefectural Assembly. In terms of national politics, the city is divided between the Saitama 1st district, Saitama 5th district and Saitama 15th districts of the lower house of the Diet of Japan.

Elections

• 2025 Saitama mayoral election

The executive mayor, who is directly elected, is Hayato Shimizu, an independent. He defeated the incumbent Sōichi Aikawa (backed by the Liberal Democratic Party and Komeito) in the 2009 Saitama mayoral election with backing by the DPJ. He has won four subsequent mayoral elections, most recently in May 2025.

Economy

Saitama's economy is principally constituted by commercial business. The city is one of many commercial centers of the Greater Tokyo area and serves Saitama Prefecture, North Kanto, and northeast Honshu.

Saitama is also home to various manufacturers, exporting automotive (Honda manufactures the Honda Legend at Sayama Plant), food, optical, precision and pharmaceutical products. Calsonic Kansei, a global automotive company is headquartered in the city. Iwatsuki is famous for manufacturing of hinamatsuri dolls and ornate kabuto (samurai helmets).

Land use

The political and administrative center of the city is Urawa Ward (Urawa Station area), and the economic, commercial, and transportation center is Omiya Ward (Omiya Station area). Located approximately 20 km to 35 km from central Tokyo, Saitama City is a satellite city and bed town in the Tokyo metropolitan area, with a day-night population ratio of 92.8 in 2010, which is less than 100 despites being the prefectural capital and an ordinance-designated city (the southeastern part of Saitama Prefecture).

Of the 747,000 commuters permanently residing in the city, 175,000, or 23.5%, commute to the Tokyo Special Wards area, making the city home to many so-called "Saitama Tomin". On the other hand, the former Urawa and Omiya cities were designated as core business cities in 1988, and in 2000, Saitama New Urban Center was opened and local branches of various central government offices were relocated from Tokyo. The southeastern area of Saitama Prefecture tends to be a suburb of Tokyo, and the day/night population ratio is particularly low in Minami ward and Midori ward, which are close to the center of Tokyo. In part for this reason, the southern part of the city, which is closer to Tokyo, tends to have a higher population density than the northern part. In addition, population tends to be concentrated along the Keihin Tohoku Line, Utsunomiya Line, Takasaki Line, and Saikyo Line, which directly connect to central Tokyo, and where both conditions overlap, there is a series of high population density areas of over 20,000 people/km2 from Minami ward to Urawa and Chuo ward.

Urban functions such as administration, commerce, and business are concentrated around major stations such as Urawa, Omiya, and Saitama-new urban stations, which have formed the central urban area since the time of the former Urawa and Omiya cities. The former Omiya City developed as a railroad town and commercial center, and Omiya Station in particular is one of the busiest and most prominent terminal stations in the Tokyo metropolitan area, with all Shinkansen bullet trains stopping there. The Urawa area is also known as an educational district with Saitama University and Saitama Prefectural Urawa High School, as well as an upscale residential area. The Iwatsuki Station area on the Tobu Noda Line (Tobu Urban Park Line) is also a part of the former Iwatsuki City's central urban area. The center of the former Yono City is Yono-honmachi Station

Transportation

Representative station is Urawa Station. Saitama is a regional transportation hub for both passengers and freight train lines. Ōmiya Station, part of the Shinkansen high-speed train network, serves as the biggest railway hub in the prefecture.

The closest major airports are Haneda Airport and Narita International Airport, both about two hours away. Honda Airport in Okegawa is for general aviation and offers no scheduled transport services. Commuter helicopter flights to Narita Airport are offered from Kawajima.
