The US Air Force's 18th Wing banned vehicles made by Chinese automaker BYD from Kadena Air Base in Okinawa, with the restriction taking effect this week.

The order turns away every BYD vehicle at the gates — privately owned cars, taxis, delivery and contractor vehicles — with security personnel instructed to block BYD drivers and turn them around.

Wing spokesperson Lieut Col Alli Stormer said the vehicles present 'an unacceptable and unmitigable risk to our personnel and our mission.'

BYD is not a fringe brand — it overtook Tesla in 2025 as the world's biggest seller of battery-electric vehicles, and it is expanding in Japan, launching its Racco electric minicar there in July to crack a market dominated by domestic brands.

A blanket gate ban at the largest US Air Force installation in East Asia is a striking escalation against the world's leading EV maker, and it echoes China's own 2021 restrictions on Tesla at some government compounds, which Beijing lifted in 2024.

US officials have not identified a specific threat, but the concern centers on vehicle-mounted cameras, sensors and GPS devices that could collect or leak sensitive information, South Korea's Yonhap news agency reported.

The SOFX Report adds context: Norway's Home Guard exercise this month found rental vehicles recorded reservists' locations, filmed personnel, and captured gate security codes, while the Dutch intelligence service warned that connected-car data can be accessed by state actors.

No public evidence shows BYD vehicles have transmitted data from Kadena.

Kadena is the biggest US air force base in East Asia and would be directly involved in any crisis involving China, Russia or North Korea.

It hosts fighters, refuelling, surveillance and reconnaissance aircraft, and since mid-October has stored the US Army's Typhon missile system, which can fire Tomahawk missiles roughly 1,600km — putting parts of China and Russia within reach.

The Pentagon added BYD to its Section 1260H list of 188 Chinese military-linked firms in June, alongside Alibaba, Baidu and NIO, which BYD rejected and is challenging legally.

The ban currently applies only to Kadena, but speculation is mounting that similar measures could follow at other US facilities.

According to SOFX, Yonhap reported comparable steps could extend to US installations in South Korea, where the military removed about 1,300 Chinese-made surveillance cameras from bases in 2024 over fears footage could route to a server in China.

It remains unclear whether other US bases in Japan will follow, and BYD has not immediately responded publicly to the ban.
