Japan announced a Chiba Prefecture initiative using laser-equipped drones to deter wild birds around poultry farms. The goal is to reduce one possible route for avian-influenza exposure—not to detect, destroy, or treat the virus. The drones are a potential addition to farm biosecurity, not a replacement for it.
What Japan actually announced
On October 2, 2025, NTT e-Drone Technology and NTT East announced a collaboration with Chiba Prefecture involving poultry farms. The project uses the BB102 drone fitted with the Kurna Move wildlife-repellent laser system, developed and supplied by the Regional Research Institute. The stated aim is to discourage wild birds from approaching poultry facilities and thereby reduce a possible risk of avian-influenza virus entering a farm environment. NTT’s announcement describes a local initiative, not a nationwide rollout.
Chiba had particular reason to focus on prevention: NTT’s announcement said that more than 3.3 million poultry were culled there during January and February 2025 amid avian-influenza outbreaks. It also reported 51 cases across 14 prefectures as of February 2025. Those are dated figures cited by the companies, not current national totals.
How the laser drone is supposed to work
The BB102 is a commercial agricultural and wildlife-management drone, not a consumer camera drone. It carries Kurna Move, which projects red and green laser light in irregular patterns. The manufacturer says the movement and flicker are intended to make the stimulus harder for birds to get used to. An operator can set an area or route for automated flight, allowing the aircraft to patrol or revisit selected locations.

- Easy to use
- Disperses birds from trees at dusk
- Simple bird solutiom
- High tech laser beams bother most birds
The intended effect is visual aversion: birds may leave a roof or avoid an area when they encounter the moving light. That is different from creating a barrier in the sky. A drone cannot guarantee that birds will not fly over a farm, approach from outside the patrol area, or land where the laser does not reach. Performance may depend on species, daylight, weather, terrain, vegetation, food availability, and repeated exposure.
Why wild birds matter—and what the evidence shows
Wild birds and their droppings can be one possible source of pathogen contamination around poultry facilities. Deterring birds from roosting or landing near a house could therefore help reduce one exposure pathway. It does not follow that every outbreak starts with wild birds, or that scaring birds away alone prevents infection.
A Japanese government agricultural-technology page describes a demonstration in which a flock of about 80 crows on a poultry-house roof was reduced after laser treatment. NTT later described a company-reported case in which 80 crows fell to zero after a week of countermeasures. These accounts support a narrower claim—that bird presence was reduced in particular settings. They do not show that the drone prevented avian influenza, establish effectiveness against every species, or demonstrate long-term results under all farm conditions. The government demonstration summary and the company’s case-study page should be read with that distinction in mind.
The available material does not establish robust, independent evidence that the system can keep migratory waterfowl away from poultry farms or reduce outbreak rates. A vendor evaluating the system should be asked for species-specific and long-term results, trial conditions, flight frequency, and evidence beyond bird counts.
Rank #2
- Great tools at an affordable price
- Uses a powerful red laser beam that disorients and startles birds, creating an effective visual deterrent that keeps pigeons, sparrows, and other unwanted birds away from indoor spaces without causing harm
- Designed specifically for interior environments like warehouses, barns, garages, and commercial buildings, providing a humane, chemical-free solution that doesn't affect people, pets, or property
It is not a pesticide replacement—or an outbreak treatment
“Forget pesticides” is a misleading comparison. Pesticides generally target organisms such as insects, weeds, or fungi; the relevant controls for avian influenza are veterinary, sanitary, structural, and operational. The laser is best understood as an active wildlife-deterrence tool.
It does not test birds, detect virus, disinfect a poultry house, vaccinate a flock, or treat an outbreak. NTT announced a separate BB102 spraying option for disinfectants, deodorants, and lime from June 1, 2026. That add-on is distinct from the laser and does not mean the laser itself disinfects anything. The spraying announcement describes that separate capability.
Biosecurity still depends on layers
Japan’s Ministry of Agriculture, Forestry and Fisheries (MAFF) treats farm biosecurity as a broader set of measures. A drone cannot replace steps such as:
- Inspecting and maintaining bird-proof netting and sealing openings in poultry houses.
- Controlling access by people and vehicles, with dedicated clothing and footwear where required.
- Cleaning and disinfecting facilities and equipment.
- Preventing contact with wild-bird droppings, contaminated water, feed, and bedding.
- Monitoring flock health and promptly reporting suspicious symptoms.
- Following official movement restrictions and other disease-control directions when applicable.
MAFF’s avian-influenza guidance covers prevention and the response required when relevant symptoms are found, including prompt reporting and movement restrictions in applicable circumstances. Bird deterrence is only one possible part of that system.

Practical limits, safety, and flight rules
The manufacturer lists the BB102’s flight time as 25 minutes, with a maximum takeoff weight of 21.2 kg and maximum wind resistance of 8.0 m/s. Actual endurance depends on operating conditions and payload. A large site may require multiple flights, battery rotation, charging logistics, weather checks, trained operators, and backup measures. A published maximum wind figure is not a guarantee that flight is safe or effective in every windy, wet, snowy, or dusty condition. The product page lists specifications and available equipment.
Automated routes are not the same as unattended operation. The operator still needs to assess the route, watch for hazards, manage batteries, and comply with flight restrictions. The manufacturer says an FPV camera can assist with roof and high-area inspection, but it does not by itself authorize beyond-visual-line-of-sight flight.
Laser use also requires care. Direct or reflected exposure can harm eyes; a beam could affect workers, visitors, neighbors, livestock, wildlife, or pilots. Drone collision or loss of control is another risk. A U.S. Department of Agriculture Wildlife Services assessment explains why laser class, power, and exposure conditions matter: a deterrent should not be assumed harmless simply because it is intended for animals. Operators should obtain a suitable laser-safety plan and avoid exposing people or aircraft. USDA’s laser-risk assessment provides safety context.
Japan’s aviation rules also apply. Aircraft weighing 100 grams or more must be registered and display a registration ID, and remote identification requirements apply. Additional permissions or approvals may be required depending on airspace and flight method, including flights near airports or in densely inhabited districts. Private ownership of the land does not make every flight unrestricted. Check the current rules and local constraints with Japan’s Ministry of Land, Infrastructure, Transport and Tourism (MLIT) before operating. MLIT’s drone overview and its permissions and approvals guidance explain the framework.

Who might find it useful?
A mobile deterrent may be worth evaluating where bird activity moves between locations, roofs are difficult to reach, or a fixed installation cannot cover the problem area. It may be a poor fit for a small flock or a single predictable roost, where netting, structural exclusion, a fixed deterrent, or a managed bird-control service could be simpler and less costly.
Before considering a purchase or service, a farm should identify the bird species and whether they are landing, nesting, roosting, or merely flying overhead. It should also check whether daylight operation is practical, how much ground must be covered, whether there is a safe launch and landing site, and how many flights are needed. Nearby homes, roads, schools, airports, heliports, livestock, and workers all affect the safety and regulatory assessment. Netting physically excludes birds from suitable structures; fixed visual deterrents serve stable areas; acoustic or pyrotechnic approaches can introduce noise, animal-stress, neighbor, fire, or permitting concerns. No method removes the need for biosecurity.
Availability and costs
NTT e-Drone Technology announced that the BB102 became commercially available in Japan on October 1, 2025. The aircraft is listed at an open price, so the public product page does not give an all-in purchase price. It lists Kurna Move Swing at ¥506,000 including tax, a charger at ¥181,500, a battery at ¥127,500, and periodic inspection at ¥110,000 including tax. Training is listed at ¥140,000 for experienced operators over three days and ¥220,000 for beginners over four days. Prices and conditions should be confirmed with the supplier before purchase. The launch announcement gives the availability date; the product page lists current specifications and price information.
From April 1, 2026, the company listed annual BB102 maintenance coverage at ¥220,000 before tax. The stated terms include facility liability insurance, allow up to two incidents per year, and specify a ¥100,000 before-tax customer deductible per repair or replacement. This is a service price, not the total cost of operating the system. Budget for the aircraft, laser, batteries, training, operator time, compliance, insurance, maintenance, replacement parts, and weather-related downtime. NTT’s service announcement sets out the maintenance terms.

The strongest supported conclusion is modest: laser-equipped drones may help disperse or deter some birds in particular settings. That could reduce one potential route of exposure around a poultry farm. The announced Chiba initiative and bird-count demonstrations do not prove that the technology prevents avian-influenza outbreaks, works against every relevant species, or can replace physical exclusion and routine biosecurity.
For poultry operators, the sensible question is not whether a laser drone “fights bird flu,” but whether it safely and reliably reduces a specific, observed bird problem at a site—and whether the benefit justifies the operational and regulatory burden alongside the farm’s existing controls.
