The first construction of this timber cantilever bridge across the Kurobe river in the province of Etchu dates back to 1662. The unique technique, in which six slanting timbers in each line cantilever out gradually from each side of the river toward its middle, was then adopted, while the wood-house building skills of carpenters were applied to the smaller parts of the bridge. It was necessary to cut and bring down lots of timbers before the start of the construction. The officials of Sakuji-sho inspected the work. Sotosakuji-bugyo, chief of one of the construction offices, directed the whole necessary work and Ondaiku of the technical section led just the construction.
