Monitor Japan From Space

Off-Nadir Delta lets you watch Japan without any GIS software. View Sentinel-1 SAR (all-weather, day or night) and Sentinel-2 optical imagery, draw any area to build a time series with anomaly detection, and overlay active fires.

The Delta Watchfloor adds the event layer: geolocated signals in and around Japan, ranked by severity, that you can connect to satellite imagery in one tip-and-cue workflow.

Frequently Asked Questions

How can I monitor Japan with satellite imagery?▼
On Off-Nadir Delta you can view Sentinel-1 SAR and Sentinel-2 optical imagery over Japan, draw any area to monitor it over time with anomaly detection, and overlay NASA FIRMS active fires. The Delta Watchfloor also shows geolocated event signals in and around Japan, so you can connect what is happening on the ground to what satellites see.
Where does the Japan event data come from?▼
Geolocated event signals are distilled from global news media — open monitoring of world events — AI-enriched and continuously refreshed. The data is for situational awareness and is not intended for tracking or targeting individuals.
Is monitoring Japan free?▼
Browsing the latest event signals on the Watchfloor is free and needs no account. Deeper capabilities — seeing what changed since your last visit, longer history, and AI remote-sensing deep-dives — are available on paid plans or metered by tokens. See the pricing page for details.
