Waymo announced that it will use Toyota bZ4X electric vehicles assembled in Japan to power a new robotaxi service in Tokyo. The announcement expands upon the strategic partnership between Waymo and Toyota that was originally revealed in April 2025.
Streamlined Assembly and Manufacturing
The upcoming robotaxis will be manufactured completely under a single roof at Toyota’s Takaoka facility located in Toyota City, Aichi Prefecture, Japan. Rather than assembling standard automobiles and altering them at a later stage, the plant will integrate Waymo’s autonomous sensors and computing systems directly onto the main assembly line during the vehicle production process.
This integration marks a significant change in how Waymo obtains and equips its fleet vehicles. Previously, the business purchased finished cars from a factory, transported them to a separate workshop, and retrofitted them with additional wiring, sensors, and computers. Integrating the sensor suite and compute systems directly into the bZ4X on the Toyota assembly line aims to reduce redundant labor, custom brackets, and secondary freight expenses, which could potentially lower overall costs for Waymo.
Broader Vehicle Compatibility and Global Expansion
The collaboration between the largest global automaker and the top autonomous driving company carries substantial industry implications. Waymo currently operates two vehicle models—the Jaguar I-Pace and the Ojai, which is built on the Zeekr RT—alongside a third model based on the Hyundai Ioniq 5 that is scheduled for deployment soon. Incorporating the bZ4X allows Waymo to demonstrate that its self-driving software functions across a diverse selection of automobile platforms, reinforcing its identity as a technology and systems supplier known as the Waymo Driver rather than a traditional car manufacturer.
According to Waymo, initial testing and validation procedures in Japan are scheduled to commence next year. Subsequent to this testing phase, the new autonomous vehicles will deploy in the United Kingdom and additional international territories for commercial robotaxi services.
Future Integration and Safety Research
Waymo stated that it continues to investigate the integration of its autonomous driving technology into Toyota models intended for private ownership. Additionally, the company is collaborating with Woven by Toyota, the automaker’s software and mobility subsidiary, to utilize Waymo operational and safety telemetry data to enhance overall road safety for standard vehicle fleets and traffic infrastructure.
