History
The area of modern Niiza has been settled since prehistoric times. It was part for Shinra County within Musashi Province in the Nara period. Shinra County (新羅郡) was originally written with the same kanji as the ancient Korean kingdom of Silla, and the area was settled by immigrants from Silla in 758 AD. The name was changed to Niikura County (新座郡) in the Heian period.[4]
The town of Owada was created within Niikura District, Saitama with the establishment of the modern municipalities system on April 1, 1889. Niikura District was abolished in 1896, becoming part of Kitaasachi District. On March 1, 1955, Owada annexed the neighboring village of Katayama becoming Niiza Town, which was raised to city status on November 1, 1970.[5]
Government
Niiza has a mayor-council form of government with a directly elected mayor and a unicameral city council of 26 members. Niiza contributes two members to the Saitama Prefectural Assembly. In terms of national politics, the city is part of Saitama 4th district of the lower house of the Diet of Japan.
In the 2021 Japanese general election, from Saitama 4th district, Yasushi Hosaka [ja] was elected.
Economy
Toppan printing has a large factory in Niiza, which is also home to a number of other light manufacturing, electronics and transportation/warehousing companies. However, due to its proximity to Tokyo, over a third of the workforce commutes daily, making Niiza largely a bedroom community.[citation needed]
Niiza has 17 public elementary schools and six public middle schools operated by the city government, and three public high schools operated by the Saitama Prefectural Board of Education. In addition, there are two private combined junior/senior high schools.
On April 7, 2003, Niiza gave the anime character Astro Boy an honorary citizenship to mark the date given as his birthdate in the original manga.[8] Later in 2004, the theme music from the TV series would eventually be used to signal the departure of a train at JR Niiza Station on the JR Musashino Line.
