By 1 April 2015, three 1010 series sets (15, 17, 19) remained in service, formed as six-car sets. The last set (set 7) was withdrawn following its last day in service on 26 June 2016.

In the early 1970s, planning for what became the Tōhoku and Jōetsu Shinkansen progressed in parallel. However, construction planning took place amid growing public concern over noise and vibration from the Tōkaidō and San'yō Shinkansen.

Opposition developed along parts of the planned Tōhoku and Jōetsu corridors. In Ina, where the two Shinkansen lines were planned to branch, residents opposed the project because the construction would divide the town into three sections. Through the efforts of then-mayor Misao Kato, an agreement was reached to construct an urban railway as compensation for the affected communities, including residents of the neighboring Ōmiya, Ageo, and Ina municipalities. A standard railway was considered excessive given the anticipated demand along the Ina corridor, so an automated guideway transit (AGT) system, then a relatively new technology, was chosen as a medium-capacity option. Residents of Toda, Urawa and Yono received a separate heavy-rail connection, which became the Saikyō Line.

Saitama New Urban Transit Co., Ltd. was incorporated on 1 April 1980, to operate the new line. The company applied for a local railway business license on 4 December 1980 and received it on 3 April 1981. Construction began on 15 October 1981 and was completed in April 1983.

The first section, between Ōmiya and Hanuki, opened on 22 December 1983. The line initially operated with 1000 series trains, and approximately half of the services ran only between Ōmiya and Maruyama; services north of Maruyama operated at 40-minute intervals during the daytime.

Construction of the remaining section between Hanuki and Uchijuku was delayed by difficulties in acquiring land from two landowners along the planned route. Negotiations with one landowner were completed in March 1988, but negotiations with the remaining landowner continued. Activists associated with the Revolutionary Communist League, National Committee, which had been involved in the opposition to Narita Airport, intervened in support of the landowner, further complicating the negotiations. The landowner and activists constructed a protest hut beneath the planned route and barricaded themselves inside. They also staged protests from a tower above the structure, including throwing feces at authorities. On 17 February 1990, Saitama Prefecture carried out an administrative execution under the Land Expropriation Law. The landowner and activists were arrested for obstruction of public duties.

Because the planned guideway passed above the landowner's property, the prefecture acquired an air right over the property rather than acquiring the underlying land. The access road beneath the elevated guideway was not included in the expropriation and consequently remains discontinuous. A mesh-fenced shelter was subsequently constructed around the guideway in this section, indicating the location where the air right was acquired.

The remaining section between Hanuki and Uchijuku opened on 2 August 1990, completing the line.

On 14 October 2007, Ōnari Station was renamed Tetsudō-Hakubutsukan (lit. 'Railway Museum') to coincide with the opening of the Saitama Railway Museum.

On 16 January 2019, a tire on the rear car of an up train suffered a puncture and blowout and derailed from the guideway between Kamonomiya and Tetsudō-Hakubutsukan. The accident suspended service on the entire line until the following afternoon, with substitute bus services provided during the disruption. Following the accident, the company began installing tire-pressure monitoring systems on its trains in 2020.

The 1050 series was withdrawn from service on 15 February 2026.
