History
Maruyama Station opened on 1983-12-22 with the start of the Saitama New Urban Transit Ina Line (New Shuttle), built beneath the elevated structure near the point where the Jōetsu and Tōhoku Shinkansen lines diverge. The Ina Line is double-tracked south of Maruyama towards Ōmiya and single-tracked north towards Uchijuku. The line's rolling-stock depot and the operator's headquarters sit on land adjacent to the station on the east side. The station has two platforms and three tracks, and some trains terminate and turn back here. The Suica IC card became usable on 2007-03-18.

Notes
Maruyama is built directly into the V-shaped point where the Tōhoku and Jōetsu Shinkansen lines diverge — three layers of viaduct stack overhead, threading the Ina Line's tracks between Shinkansen piers, with Saitama New Urban Transit's depot and headquarters on the same parcel.
