Nippon AED Map helps people find nearby AEDs on a map when an emergency happens. It draws on a nationwide AED map that gathers AED location information from across Japan, so the main task it supports is locating a defibrillator close to where you are.

Finding a nearby AED during an emergency

The app is built around the Japan nationwide AED map. When you need a defibrillator, the map is the starting point: the app shows AED locations from across the country, which lets you look for one in the area around you.

Using GPS to show AEDs near you

To display nearby devices, the app uses the GPS information of your device and places neighboring AEDs on a map. This removes the need to search for locations manually. The app advises turning on your device's position information, such as GPS, because this is needed for accurate AED search and display on the map.

Correcting and contributing AED data

The AED map depends on information gathered from users. By tapping an AED marker, you can correct data that is unpublished or wrong. The source describes this as a crowdsourced approach in which general users can help improve the accuracy of the map and the database.
