Toyota and Waymo are taking their autonomous driving partnership to the next level, with plans to introduce a fleet of fully autonomous Toyota bZ4X electric SUVs in Japan starting in 2027. The collaboration represents a major step toward expanding Waymo’s global robotaxi operations and marks an important milestone for Japan’s emerging autonomous mobility industry.

Building on the preliminary agreement announced in April 2025, the two companies will begin initial operations in Japan in 2027 to test and validate autonomous Toyota bZ4X vehicles equipped with Waymo’s self-driving technology. Following the Japanese launch, the partnership is expected to expand to the United Kingdom and other international markets where Waymo already operates, although those deployments are planned for the following years.

The project will combine Toyota’s extensive automotive manufacturing experience with Waymo’s fully autonomous driving technology, with the shared objective of accelerating the global deployment of Level 4 autonomous vehicles.

Toyota bZ4X to Become Waymo’s Next Robotaxi

At the centre of the collaboration is the Toyota bZ4X, the Japanese manufacturer’s all-electric SUV, which will be specially adapted to accommodate Waymo’s autonomous driving hardware and software.

Unlike conventional vehicle conversions, Toyota plans to manufacture and equip the autonomous bZ4X fleet at its Takaoka plant in Toyota City, Aichi Prefecture. The entire production process will take place under one roof, covering everything from assembling the base vehicle to integrating Waymo’s autonomous driving hardware.

This approach is expected to streamline production, improve integration between the vehicle and self-driving systems, and provide a scalable manufacturing foundation for future autonomous fleets.

The decision to use a high-volume, domestically manufactured Toyota model is particularly significant for Japan, where the partnership aims to establish the country’s first fully autonomous ride-hailing service based on mass-produced domestic vehicles.

Level 4 Autonomous Driving Focuses on Safety

The Toyota-Waymo partnership is built around the development and deployment of Level 4 autonomous driving technology.

Unlike Level 2 and Level 3 systems, Level 4 autonomous vehicles can perform all driving tasks within defined operational conditions without requiring human intervention. This makes them particularly suitable for commercial robotaxi services operating within designated geographical areas.

Waymo will contribute its fully autonomous Waymo Driver technology, while Toyota will provide its vehicle engineering, manufacturing capabilities and extensive experience in developing safety-focused automobiles.

According to Waymo co-CEO Dmitri Dolgov, the company’s autonomous vehicles have demonstrated performance of up to 20 times better than human drivers in terms of serious crash injuries in the areas where Waymo operates.

Dolgov highlighted Toyota’s reputation for safety, reliability and quality as important factors behind the partnership, adding that the collaboration will help bring autonomous mobility to more people, including customers in important international markets such as Japan.

For Toyota, the initiative is closely connected to its long-term ambition of achieving zero traffic accidents. The company believes that autonomous driving technology could significantly reduce accidents caused by human error while improving mobility options for people who cannot easily drive or access conventional transportation.

Autonomous Toyota bZ4X Designed for Passenger Comfort

Beyond its self-driving capabilities, the autonomous Toyota bZ4X will receive several modifications aimed at improving passenger comfort, convenience and accessibility.

The specially equipped electric SUV will feature generous rear-seat legroom, automatic doors, a power-operated liftgate and ambient interior lighting.

These features are designed to make entering and exiting the vehicle easier, particularly for passengers with reduced mobility, older people and those who may require additional assistance when using conventional transportation services.

The focus on accessibility highlights an important aspect of the autonomous mobility concept. Robotaxis are not simply intended to replace traditional taxis or ride-hailing services. They could also provide new transportation opportunities for people who cannot drive because of age, disability or other mobility limitations.

Toyota and Waymo Look Beyond Robotaxis

The partnership will extend beyond commercial autonomous ride-hailing services.

Toyota and Waymo will continue exploring how autonomous driving technology could eventually be integrated into personally owned Toyota vehicles. The companies will also work alongside Woven by Toyota, Toyota’s mobility technology subsidiary, to investigate additional opportunities for improving road safety.

One particularly important area will be the use of real-world operational data collected by Waymo’s autonomous fleet. Insights generated through its driving operations, data analysis and autonomous technology could help Toyota develop safer vehicles and improve the overall transportation ecosystem.

The companies are also interested in how vehicle technology could interact with road infrastructure to create safer driving environments for everyone, including pedestrians, cyclists and conventional vehicle users.

Toyota executive vice president Hiroki Nakajima emphasised that safety technologies deliver the greatest benefits when they can reach as many people as possible. He also stressed that achieving the company’s ambition of zero traffic accidents will require cooperation between automotive manufacturers, technology companies and other mobility stakeholders.

A Major Step in the Global Robotaxi Race

The Toyota-Waymo agreement comes at a time when the global autonomous mobility industry is entering a new phase. Robotaxi services are gradually moving beyond experimental programmes towards larger commercial operations, increasing the importance of reliable vehicle platforms and scalable manufacturing processes.

For Waymo, Toyota represents an important manufacturing partner capable of supplying vehicles produced at significant volumes, while the Japanese automaker gains access to one of the world’s most advanced fully autonomous driving technologies.

The planned 2027 Japanese operations will be an important test of how effectively the two companies can combine their respective expertise in a market with its own regulatory, infrastructure and traffic challenges.

The subsequent expansion to the United Kingdom and other Waymo-serviced markets could further strengthen the partnership’s international ambitions.

Although autonomous driving still faces technological and regulatory challenges, the collaboration demonstrates that the future of robotaxis will depend not only on sophisticated artificial intelligence and sensors, but also on established automotive manufacturers capable of producing safe, reliable and commercially viable vehicles.

With the electric Toyota bZ4X serving as the foundation, Toyota and Waymo are positioning themselves to play a significant role in the next generation of autonomous transportation.
