• JR Musashino Line: Kita-Asaka ⇄ Higashi-Tokorozawa

Niiza Station opened on 1 April 1973 on the JNR Musashino Line, in Nobidome, Niiza, Saitama. It was one of twelve stations across the country where automatic ticket gates were first trialled at opening. The station passed to JR East at privatisation on 1 April 1987, and Suica IC fares became valid on 18 November 2001. Although surrounding land remained largely undeveloped vineyards for nearly thirty years, the south plaza was redeveloped in 2002. Since 11 April 2004 the departure melody has used the Astro Boy theme, adopted to mark the first anniversary of Astro Boy's birth; the character is registered as a special resident of Niiza City, where Tezuka Productions is based. The Midori no Madoguchi closed on 31 May 2020.
