Okuōikojō Station (奥大井湖上駅, Okuōikojō-eki) is a train station in Kawanehon, Haibara District, Shizuoka Prefecture, Japan, operated by the Ōigawa Railway. Okuōikojō Station is served by the Ikawa Line and is located 13.9 kilometers from the line's official starting point at Senzu.
Description
Background
Okuōikojō Station opened on the current position on October 2, 1990, when part of the Ikawa Line was rerouted to avoid the lake's rising waters caused by the Nagashima Dam. Technically, the Oigawa Railway treats the station as the renamed and relocated Inuma station, which was submerged by the mentioned dam. Taking this into account, the actual opening year for the station is 1959. Despite the area around the relocated station lacking any residents living nearby, Oigawa Railway proceeded with the construction of the station to attract tourists.
Layout and surroundings
The station has one side platform serving a single track, with a small shelter on the platform for passengers. The station is unattended. Located on a cliff next to the Okuōi Reservoir created by the Nagashima Dam, the station platform partially extends onto a bridge spanning the reservoir. The bridges on both sides of the station is named the "Okuōi Rainbow Bridge".

Why this record matters
The subject matters to the places & architecture register because the source frames it as railway station in Kawanehon, Haibara district, Shizuoka prefecture, Japan. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Place names and jurisdictional language are key evidence: both can reveal earlier catalogue descriptions and overlooked record series. The source revision retrieved here is dated Aug 23, 2026. The linked authority identifier is Q7082786. Authority coordinates are 35.168, 138.181. 2 of 2 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1990 and 1959.
Architectural summaries often privilege surviving fabric and can understate demolished phases, contested use or displaced communities. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
