History
Yasaka Station opened on 1 October 1942 — in the midst of the Pacific War — on the Seibu Tamako Line in Higashimurayama, Tokyo. Construction of the Army Boy Signal Corps School and an Army ordnance supply branch along the line had prompted military authorities to require a stop here, even as other lines toward the Murayama and Yamaguchi reservoirs were being shut down to save resources, leaving the Tamako Line to keep running. The platform was lengthened to take eight-car trains in 1996, and the 2000 station rebuild — synchronised with a four-laning widening of Tokyo Metropolitan Route 17 (Fuchū Kaidō) — placed the new building and platform on the opposite side of the single track from the original.

Notes
Yasaka is one of the few Japanese stations to have switched platform sides during reconstruction — the new building put up around 2000 was placed across the single track from the original ground-level station.
