A roof built from old rails
The platform roof at Nihongi covers the island platform on the west side of the station, and its columns hold a small surprise. They are made from used rails rather than fresh steel sections: American rails rolled in 1923 (Taisho 12) and rails from the Yawata Steel Works dated 1929 (Showa 4).
Each column pairs two old rails welded head to head. Their tops are bent outward and inward into brace-like arms that carry the beams supporting the roof. What looks at first like ordinary station ironwork is in fact a careful piece of reuse.
Thrift turned into structure
Built in 1937 (Showa 12), the roof spans about 262 square meters in steel. Reusing worn rails as columns was a practical habit of prewar Japanese railways, when good steel was worth keeping in service in a second life.
The roof was listed as a Registered Tangible Cultural Property in September 2019 for its contribution to the historic railway landscape. It is classed among structures (sono-ta kosakubutsu) rather than buildings, a reminder that a platform canopy is engineering as much as architecture.
Where to look on the platform
Stand beneath the canopy and study the columns. Rolling marks and profiles can still be read on old rails, and the head-to-head welds show plainly where two rails became one post.
Follow a column up to where it splits into the curved arms that receive the beams, a neat solution to turning a straight rail into a roof support. From here the reversing trains of the switchback are in easy view, framed by a roof more than eighty years old.

Q&A
- What are the platform columns made of?
- Used rails rather than new steel: American rails rolled in 1923 and Yawata Steel Works rails from 1929, with two rails welded head to head to form each column.
- When was the platform roof built?
- In 1937 (Showa 12), with later repairs in the Showa 50s. It covers about 262 square meters.
- Why were old rails reused?
- Reusing worn rails was common practice on prewar Japanese railways. Sound steel was kept in service as columns and beams once it was no longer used for running trains.
- Can I see the rail markings myself?
- Often, yes. The columns are in the open on the platform, and rolling marks or rail profiles can sometimes be made out up close. Please stay clear of the platform edge and running lines.
