Harumi Bridge, Railway bridge in Harumi, Tokyo, Japan

Harumi Bridge is a steel railway bridge over the Harumi Canal, linking Harumi in Chuo ward with Toyosu in Koto ward. It is a single-span through-type Rosen truss: one curved arch rises above the flat deck, joined to it by vertical and diagonal struts, with a low lattice railing along the sides. The span is 58.8 m, carried on massive pale grey concrete piers standing in the water; the steel is painted a weathered dark reddish-brown.

The bridge was built in 1957 as a rail line for port operations and transported cargo between neighborhoods for decades. Operations ended in 1989, leaving the structure as a reminder of that industrial era.

The bridge shows how ports and water transport shaped Tokyo's growth over time. You can see from its structure how the city relied on ships and railways to move goods across its neighborhoods.

The bridge now forms part of Harumi Bridge Park and has been open as a park promenade since 19 September 2025, after seismic reinforcement. The walkway crosses the Harumi Canal between Harumi and Toyosu; the deck is reached via the park paths at either end, and the low lattice railing runs along the sides.

The bridge was designed by the Japanese National Railways Tokyo Construction Bureau and its steel girders were built by Ishikawajima Heavy Industries. It is a deck-type Lohse arch, a single 58.8 m span carrying one track, and it reopened on 19 September 2025 as a walkway within Harumi Bridge Park.
