In the case of a cardiac arrest, every second counts, which is why over the past decade Japanese health organizations have deployed a large number of automated external defibrillators (AEDs) in public areas, with the current count somewhere over 300,000 units.
Eventually the country would like to see that number expand to one in every building, but for the time being the first priority is AED accessibility, leaving some foreign tourists surprised to find that AEDs in places that might seem a little odd at first: like vending machines.
