Shin-Arakawa Bridge: 1 Live Camera in Japan

Shin-Arakawa Bridge on the Arakawa, seen from the Kawaguchi side and refreshed every minute. It is 21.4km from the mouth, and the far bank is Kita in Tokyo.

What you can see

This camera watches Shin-Arakawa Bridge, which carries Route 122, from the Kawaguchi side in Saitama. It stands 21.4km from the mouth.

Here the river itself is the boundary. The near side, where the camera is, is Kawaguchi in Saitama; the far bank is Kita in Tokyo. Cross the bridge and you change prefecture, so the border is in the picture.

Most of the frame is open water, with the far bank running low behind it. A red and blue structure sits back from the waterline and a tower stands to its right. The water is wide enough that on a windy day you can read the chop straight off the surface.

Just downstream is Iwabuchi Floodgate, where the Arakawa splits into the flood channel and the Sumida. It has a camera of its own.

The picture is replaced every minute, with the place name burnt into the bottom left.

When to watch

Most useful in heavy rain and typhoons. This is well up the Arakawa's ten cameras, so the water rises here before the downstream stretches. If it is climbing toward the levee here, Adachi and Edogawa will follow. But decide whether to evacuate from what your local authority says.

On calm days, morning and evening. Water fills most of the frame, so it blows out white in the middle of the day; in low light you can make out the buildings on the far bank.

In winter the air is clear and the far bank keeps its outline deep into the frame. At night almost nothing shows.

If it isn't showing

All ten cameras from the upper river to the mouth are gathered in The Arakawa. Just upstream is Sasame Bridge, and just downstream Iwabuchi Floodgate.

Cameras with a bridge in the frame are in Bridges, and the cameras of the same prefecture in Saitama.

Every river camera is in River, and the article is Why river cameras exist.
