History
Oyahana Station opened on 27 October 1914 on the private Chichibu Railway Main Line, where it sits 49.2 km from the line's eastern terminus at Hanyū. It received the station number CR26 alongside the system-wide assignment, and on 29 January 2020 the secondary name "Mt. Minoyama Climbing Entrance" was added in cooperation with the local tourism board. PASMO IC-card acceptance began on 12 March 2022, at which point the station was simultaneously destaffed; before that day it had been operated under contract from Yorii Station with reduced weekday windows. Today it remains a passenger stop with one side platform and one island platform serving three tracks, the third of which is reserved for freight movements.

Notes
Although Chichibu Railway carries about 400 passengers a day through Oyahana, the station's third track is reserved for freight and remains visibly heavier than the others — a holdover from the line's role moving limestone out of the Chichibu basin.
