Since the 1980’s, Japanese farmers have been utilizing drones to air spray fertilizer and pesticides on their crops, originally introduced by Yamaha. Today, around a third of all rice produce has been air sprayed by agricultural chemicals. The rapidly ageing population of Japan is making the hefty price (approx. $100,000/drone) an ever more common investment. Yamaha recently won regulatory approval to fly these drones in the United States, and expects to gain this in Europe in the near future.
