Tesla expands its FSD test fleet in Japan; launch targeted for end of 2026

Tesla is expanding its FSD testing program in Japan, adding the Model Y to its fleet to collect data across vehicles of different heights. The company regards Japan as one of the most difficult environments for autonomous-driving systems, owing to narrow streets and specific rules — such as the mandatory full stop before pedestrian crossings. The target launch is end of 2026; the president of Tesla's Japanese subsidiary said the company is "trying everything we can to implement this system by 2026."

The market is already prepared to a degree: by available figures, about 40,000 Teslas operate in Japan and could receive FSD via a software update once it is approved. The testing is aimed at adapting the system to local road conditions and requirements.

Importantly, expanding the test fleet is a preparation stage, not a launch: until regulatory approval is obtained, FSD (Supervised) does not become available to Japanese owners, and the stated end-of-2026 timeframe remains a goal rather than a confirmed date. As in other markets, FSD (Supervised) remains a driver-assistance system: responsibility for control stays with the human, who must supervise the drive at all times.

Japan fits into a broader global map of the FSD rollout, in which a number of countries already have access to the system while others are at testing and approval stages. The specific timeline in each country depends on national regulatory procedures.
