Saitama Live Cameras in Japan — 2 official webcams
Two river cameras on the Arakawa: Sasameba Bridge in Toda and Shin-Arakawa Bridge in Kawaguchi. Both look across at Tokyo — this is the stretch where the river is the border.

28.8 km from the river mouth. Where National Route 17 crosses the Arakawa, seen from the Toda side. From here down, the floodplain stays wide the whole way.

Shin-Arakawa Bridge
Kawaguchi, Saitama · River
21.4 km from the mouth. Route 122's Shin-Arakawa Bridge from the Kawaguchi side. The far bank is Kita ward, Tokyo — the river is the prefectural border.
When to watch
Both belong to the Arakawa-Karyu River Office of the Ministry of Land, Infrastructure, Transport and Tourism, and both refresh a still image every minute. Sasameba Bridge (Toda, 28.8 km from the mouth) carries the Shin-Omiya Bypass of Route 17 across the river, with Itabashi Ward on the far bank. Shin-Arakawa Bridge (Kawaguchi, 21.4 km) carries Route 122, with Akabane in Kita Ward opposite.
These two are the upstream end of the line of cameras on the lower Arakawa. Nine of them run down to Shinsuna at the river mouth, so in heavy rain you can work down the Arakawa page from the top and follow the water rising.
On an ordinary day, the floodplain is the thing to watch. On the Saitama side the levees are set far apart, leaving a long run of sports grounds and rough grass. That is what goes under first when the river rises, so you can see the change without reading a single gauge. Morning and late afternoon avoid the worst glare and let you see the far bank.
