History
Iriuda Station opened on 1 October 1935 when the Hakone Tozan Railway, founded in 1928, converted its Odawara-Hakone-Yumoto tramway into a fully fledged railway. The station has two opposed side platforms connected by a level crossing. Station numbering arrived in January 2014, when the stop was designated OH50. Iriuda hosts an adjacent depot, and the segment from here to Hakone-Yumoto carries a three-rail dual-gauge track to accommodate both narrow-gauge Odakyu trains and the wider Tozan stock.

Notes
Because the depot can only be reached from platform 2, only platform 2's track carries the third rail; platform 1 remains pure narrow gauge.
