History
Kita-Ageo Station opened on 17 December 1988 on the Takasaki Line in the city of Ageo, Saitama, as one of the very first new stations added soon after JNR's privatisation. Proposals for a station between Ageo and Okegawa had been raised by Ageo's mayor in March 1986; JNR approved the plan in January 1987, the JR East era began in April that year, and ground was broken in August 1987. The construction sparked a long-running dispute with the adjacent Saitama Prefectural Ageo High School and the surrounding community, and the May 1988 mayoral election briefly halted work before the project resumed in July with a revised schedule.

Notes
Opening-day protests included a balloon release in which demonstrators sent black balloons aloft, each marked with the Japanese character "gi" — meaning "doubt."
