In the United States there is a social movement called Rails-to-Trails. Its purpose is to convert abandoned rail lines and grades into pedestrian/bicycle trails, preserving our industrial heritage from development. This line, though short, looks like the perfect candidate. The views of the bridge and tunnels are very scenic, and it would link the sports fields to the town across the river. I may never visit this place, or even Japan, but I hope that this is the future of the line, and not demolition.
