It connects the eastern and northern part of Kawaguchi to Tokyo; areas that were previously only served by buses.

The original alignment was planned to serve eastern Urawa and central Kawaguchi in Saitama.

The line opened on 28 March 2001, ahead of the 2002 FIFA World Cup, which held several matches at the Saitama Stadium, half an hour on foot from the terminating Urawa-Misono Station.

Urawa-Misono Station was built as a temporary terminal as the line was planned to be extended further north in the future so it only has platforms long enough for six car trains.
