Former Harumi Railway Bridge: Four Rails, No Trains

Inside a green steel arch bridge: riveted green cross-braces repeat overhead above a wooden deck with two pairs of rails down the middle, walkers and a dog in the distance and a high-rise tower beyond
Inside the arch. The towers came later.

The footpath across this bridge has four rails set into it. It was never a double track: the bridge was only ever wide enough for one train.

I walked over from Tsukishima, on Tokyo's waterfront, and stepped on at the Harumi end, with the rails running on ahead.

The inner pair are guard rails. If a wheel came off the outer pair above the canal, they were there to keep the train on the bridge.

Nobody crossing it now is in any danger of derailing.

Freight

The bridge opened in 1957 on the Harumi Line, a freight line that crossed the canal from Toyosu to the wharves at Harumi. It was one of the city's port lines, and between them they carried coal, coke, salt, newsprint, rice, wheat and mandarin oranges.

For a freight line, it was a lot of bridge. The green arch in the middle was the first Lohse arch built for a railway in Japan, and the concrete spans on either side were the first of their design on a Japanese railway too.

The steel span was fabricated by Ishikawajima Heavy Industries, the company that became IHI. The dock of its old shipyard is a few minutes' walk from the Toyosu end.

Then freight moved onto the roads. The port lines closed one after another, and the Harumi Line, the last of them, went in 1989.

Off limits

There was talk of taking the bridge down. Partly for reasons of budget, a port official has said, it was closed off instead.

It was a railway bridge for just over thirty years. It was a closed one for more than thirty-six.

In those years it became one of Tokyo's favourite abandoned railways, partly because the road bridge alongside gives such a close view of it.

In September 2025, it reopened as a footpath, part of Harumi Bridge Park.

The deck

Turning it into a footpath was not a matter of laying boards over the old line. The rails came up, along with the sleepers and the stones beneath them. The bridge was repaired, and the rails went back into the new deck.

Here and there, the deck has windows in it.

Three glass panels set into a wooden deck between rusty rails, showing wooden sleepers and rounded stones beneath, with a tower reflected in the middle pane and water beyond the railings
Sleepers and stones under glass. The tower in the middle pane is a reflection.

Through the glass is not the canal. It is sleepers, with stones packed between them: the bed a railway track lies on. Over the steel arch, the windows show only sleepers. The stones are on the concrete spans.

From the water

From the waterside path at the Toyosu end, the arch turns out to be the showy part of a longer bridge, repainted in the green it wore when it was built. On either side of it, the bridge is grey concrete, standing on piers in the canal.

For years, the closest most people got was the road bridge next door. Now the bridge has windows in its floor, and you can look right into it.
