The Okuoi Rainbow Bridge is a huge iron bridge built in front of and behind Okuoi Kojo Station on the Oigawa Railway Igawa Line, deep in the remote mountains of Shizuoka Prefecture.
It was opened before the “Rainbow Bridge” in Tokyo Port, and is called the Okuoi Rainbow Bridge to distinguish it from that.
The sight of the train running across the emerald green lake is truly a sight to behold.
