Kiritappu Bridge, Iron arch bridge in Hamanaka, Hokkaido, Japan

Kiritappu Bridge carries Hokkaido Prefectural Road 1039 across the boundary between Hamanaka Bay and Biwase Bay, linking the Kiritappu Peninsula with the Kushibetsu district. Rebuilt in 1999 as a Rosen bridge, it stands beside the town road Shioji Bridge. The surrounding low wetland is prone to tsunami damage.

A Kiritappu Bridge first stood here in 1887. The 1960 Chile tsunami destroyed it and broke the tombolo linking the wetland to the Kiritappu Peninsula. The present bridge was built in 1961 and rebuilt in 1999 as a Rosen bridge, a tied-arch type.

The bridge links the Nemuro-Kushiro area's Kiritappu district with the Kiritappu Peninsula, where Hamanaka's town centre, the town hall, post office and Kiritappu Onsen sit. A parallel town road bridge, Shioji Bridge, crosses alongside. The wetland side meets Hokkaido Prefectural Road 123, the Betsukai-Akkeshi line.

The bridge carries Hokkaido Prefectural Road Route 1039 between the Kiritappu Peninsula and the Kushibetsu district, with the parallel town road Shioji Bridge alongside it. The area is prone to tsunami damage after earthquakes, so check evacuation routes and signage before crossing.

The 1999 rebuild made it a Rosen bridge, a tied-arch type with inclined hangers. It stands beside the town road's Shioji Bridge, and the two carry Route 1039 across the channel between Hamanaka Bay and Biwase Bay, linking the Kiritappu Peninsula to the Bogakubetsu district.
