Kadena Air Base on Okinawa, a U.S. air base in Japan, has ordered its gate security to refuse every vehicle made by BYD. The instruction was reported on Oct. 23, 2026, and it reaches beyond private cars to taxis, delivery vans and contractor vehicles. A base spokesperson, Lt. Col. Alli Stormer, described the vehicles as an “unacceptable and unmitigable risk” to the installation.

The order was first reported by Yonhap News Agency, according to the Carscoops account of the story, with Reuters and Anadolu Agency also carrying the story. Nothing in the reporting says how many BYD vehicles currently enter Kadena each day, and the base has not been quoted on the number of drivers affected. What the reports establish is the rule itself: no BYD, with no carve-out for work vehicles.
The order at the Kadena gate
Carscoops, in its report on the ban, wrote that security personnel have been told to turn away all BYD vehicles, including taxis, delivery vehicles and contractor vehicles. The same report says the restriction is set to take effect on Monday, which falls on Oct. 26 after the Oct. 23 publication date. Anadolu Agency’s report on the planned ban carried the same account of the instruction, and Carscoops attributes the spokesperson’s statement to Reuters, whose Oct. 23 report is the source of the quote.
The all-vehicles wording matters on a base that depends on outside traffic. Kadena’s own driving guide describes dense Okinawa traffic with many small vehicles, taxis and trucks, so a rule that names taxis and delivery vehicles reaches into the daily mix of cars that approach the gate. The wording of the instruction, as Carscoops reports it, leaves no room for a vendor or a taxi company to claim an exemption.
What the base spokesperson said and did not say
Stormer, speaking for Kadena and quoted by Reuters, said the vehicles present an “unacceptable and unmitigable risk” to the base’s personnel and its mission. The quote is the closest thing in the reporting to a stated reason, and it is deliberately broad: it names personnel and mission but no mechanism, no model and no date of discovery. Carscoops frames the instruction itself in plain terms, writing that security personnel have been told to turn away all BYD vehicles. She did not say what prompted the action, according to Carscoops, and the base has not described any specific incident, device or finding that led to it.
Reports cited by Carscoops suggest the concern is that the cameras and sensors fitted to modern BYD cars, trucks and SUVs could capture sensitive military information from the base. That reading is the reporters’ interpretation, not a stated finding from Kadena, and no technical assessment of any BYD model has been published in the material reviewed. The scope is set by brand, not by model: an instruction to turn away all BYD vehicles treats every BYD nameplate alike at the gate, whatever its battery, camera package or software version, and Carscoops does not report a vehicle count or a list of exempt models. The practical effect falls on whoever drives to the base for work, from contractors to taxi drivers.
Earlier data worries and a similar rule in Israel
Concern over connected BYD vehicles predates the Kadena order. When BYD entered the South Korean market, Yonhap reported in February 2025 that market watchers worried the Atto 3’s connected features, including over-the-air updates and navigation, could send driver data to China. In that Korea Times report of Yonhap’s story, Yom Heung-yeol, professor emeritus of cybersecurity at Soonchunhyang University, said BYD “must disclose exactly what types of data are collected and how they are processed.” BYD Korea responded that data collected in Korea is managed locally and not shared with headquarters in China.
Military bases elsewhere have set limits on Chinese-made vehicles. In August 2025, Calcalist reported that the Israel Defense Forces was barring Chinese-made vehicles from its bases over concerns that sensors and cameras could leak information, starting at the Tzrifin C4I base and then widening to all electric vehicles. Owners there were told to park in designated areas away from key facilities, and Calcalist noted that Chinese brands made up nearly 25 percent of Israel’s car imports last year, so the rule affects many personnel. The Kadena instruction, as reported, goes a step further and turns the vehicles away at the gate. The Israeli military’s spokesperson unit declined to comment on its rule, according to the same report.
The Kadena order stands as a base-level instruction reported through news accounts, and the text of the written order was not quoted in the sources reviewed. Whether it extends beyond Okinawa to other U.S. installations in Japan is not stated, and BYD has not been quoted in the coverage reviewed.
