Arakawa Bridge, Railway bridge in Nagatoro, Japan
Arakawa Bridge crosses the Arakawa River between Nagatoro and Minano with a structure built from granite and brick strengthened by concrete supports. The arched design allows water to flow freely beneath while creating a strong passage for trains above.
It opened in 1914 as part of the Chichibu railway's expansion plan, which was essential for creating better connections across difficult terrain. The construction addressed specific challenges caused by soft ground conditions that made building elsewhere problematic.
This structure links two areas shaped by river activity and geological significance, and locals have long used it as a key passage through the region. The crossing reflects how communities adapted to the natural landscape around them.
You can walk to the structure from nearby railway stations in just a few minutes depending on which side of the river you approach from. The easiest access varies based on your starting point along the train line.
It holds the distinction of being the longest structure along the entire Chichibu railway line, yet still retains original granite and brick from when it was built. This blend of historic material and later reinforcement is clearly visible when you cross it.
