Applying pesticide, fungicide and fertiliser across the fields at the right time, traditionally with a backpack or tractor-mounted sprayer.

Where this applies
The ministry's own report on drone use in agriculture, dated March 2026, read in full. It states that the cumulative area sprayed with pesticide, fertiliser and similar materials by drone passed one million hectares in fiscal 2023 and continued to expand, at about 1,196 thousand hectares in fiscal 2024 (an estimate); that sales of spraying drones have run at roughly 3,000 to 4,000 a year, rising slightly to 3,359 in fiscal 2024; and that 1,461 pesticides suitable for drone spraying were registered by the end of fiscal 2024. Its own method note says the area was compiled from operators' reports in 2016–2018, estimated from prefectural data in 2019 and from flight-time reports in 2020, not compiled in 2021, and estimated from registered aircraft and average area per aircraft from 2022 onward; the series therefore mixes methods and is not a reliable growth rate. Cumulative area counts a field once per spraying. It establishes the scale of drone spraying in one country; it does not count farmers, or say how many use drones themselves versus hiring a service.
What this means
Japan's agriculture ministry estimates that drones now spray pesticide and fertiliser over more than a million hectares of cumulative farmland area a year, with thousands of spraying drones sold annually.
What it does not yet show
The figures are estimates made by methods that changed between years, so they show scale rather than a reliable growth rate, and they do not say how many farmers use drones or how many hire a service.
What you can check
Find out whether drone spraying is available as a service near you, and whether the pesticides you use are approved for it.
Does it change the assessment?
No. The impact index is never moved by a single event. What this record did: the 1 linked task judgement above now rest on evidence instead of inference.
