River
The Ota River System: 3 Live Cameras in Japan
The river that built the Hiroshima delta, the Nenotani that joins it at Kabe, and a gate that decides whether a tributary drains or holds.
What you can see
All three are fixed on one spot: two on tributaries, one on the main stem.
Shinkawa Bridge on the Nenotani watches a tributary that enters the main stem around Kabe.
The Misasa River drainage gate is a sluice in the Ota system. When the main stem rises, this is where it is decided whether the tributary's water goes out or is held back — a camera on a facility more than on a river.
Below Asa Bridge shows the Ota, the river that built Hiroshima's delta, on the reach just before it enters the built-up city.
Two tributaries and a main stem let you follow what becomes of side-valley water on the edge of the city.

When to watch
Heavy rain and typhoons are when these matter. When the main stem below Asa Bridge is up, open the Misasa gate and you see how the tributary side is being handled. Decide about evacuation from your local authority. The cameras here are for seeing how things look.
The worse the day, the darker the picture, and raindrops blur the lens. Do not expect much of the image.
On a calm day below Asa Bridge is the one to watch: you can see how wide the river that made the delta has grown before it reaches the city. The operator publishes no best season, and we do not set one here.
If it isn't showing
The source is the Chugoku Regional Bureau of the Ministry of Land, Infrastructure and Transport. These are test feeds and can stop without notice. How to tell why a screen is blank is in What is happening when a live camera shows nothing.
All three are in Hiroshima.
The same prefecture also has The Ashida River System and, across the prefectural line, The Gono River. The sea this river runs out into is in The Seto Inland Sea.
