History
Hakusan Station opened on 30 June 1972 as part of the Toei Subway Line 6 in Tokyo's Bunkyō ward, beneath the Yakushi-zaka slope on the old Hakusan-dōri. Line 6 was redesignated the Mita Line on 1 July 1978, and the station was assigned the line code I-13. The platforms are built on a 500-metre curve dictated by available right-of-way, and the construction contract for the Sasugaya section was switched mid-build from cut-and-cover to a caisson method when poor ground and abundant groundwater were discovered north of the station. PASMO acceptance began on 18 March 2007. Ridership dipped after the Namboku Line's Hon-Komagome opened nearby in 1996 but has recovered since the mid-2000s as Toyo University expanded its Hakusan campus.

Notes
The two ticket gates A1 and A2/A3 sit at the foot and top of Yakushi-zaka and are labelled "Hakusan-shita" (lower) and "Hakusan-ue" (upper); passengers cannot move between the two paid areas without first leaving the station.
