• Nippori-Toneri Liner: Yazaike ⇄ Kohoku (Tokyo)

Nishiaraidaishi-nishi Station opened on 30 March 2008 with the launch of the Nippori-Toneri Liner, the elevated automated guideway run by the Tokyo Metropolitan Bureau of Transportation in Adachi, Tokyo. Station numbering was introduced across the line in November 2017, and this stop received the code NT09. The platform layout is one island serving two tracks on the elevated viaduct. The stop's working name during construction was "Kaminumata-higashi-kōen" after a nearby park, but a 2006 public poll in Adachi Ward picked the current name by a wide margin, citing the cultural pull of the nearby Nishi-Arai Daishi temple even though the temple lies about a kilometre east.

In Adachi Ward's 2006 name poll the runner-up "Kaminumata-higashi-kōen" took 122 votes against the winner's 957, with the ward's recommendation citing the crowds drawn by the Nishi-Arai Daishi temple's seasonal flowers and events as indispensable to enlivening the areas along the line.
