Nagoya's flood dashboard does the measuring, not the deciding — real-time rainfall and river-level readings reach residents online, but every floodgate and evacuation order still needs a city official's sign-off.
what does this mean?
The strongest source is the operator's or the city's own reporting — an official report, dataset or press release. It grades who did the looking — not how well the project went.

Nagoya's Crisis Management Bureau publishes real-time rainfall and river water-level readings citywide through NICOS, the Nagoya City Flood-Fighting Information System. The dashboard layers the city's own rain gauges and water-level sensors with Ministry of Land/Shonai River Office and Aichi Prefecture data, plus live monitoring-camera images of roads and rivers, so residents can check conditions near home before deciding whether to evacuate. The system only publishes information — pumps, floodgates and evacuation orders still require a human decision by city officials.
