History
Sendaira Station serves the city of Tomioka in Gunma Prefecture and is operated by Jōshin Dentetsu on its Jōshin Line, 29.9 kilometres from the Takasaki terminus. It opened on 18 August 1911 and has been in continuous service since. The station has a single side platform with only a shelter, and is unattended. It sits in an isolated rural area near the Kabura River and National Route 254, with a small post office and convenience store nearby. The Jōshin Line runs along the plain alongside National Route 254 as far as Nanjai before climbing into the mountainous Shimonita section that begins at Sendaira.

Notes
When the line opened in 1897, Shimonita's silkworm farmers feared steam-locomotive soot would harm sericulture, so the railway was routed through the mountains beyond Sendaira instead of along National Route 254; brick tunnels from the original light-rail alignment still stand on the hillside.
