SoftBank and Toyota partner to develop mobility services powered by autonomous cars, combining SoftBank's focus on IoT and Toyota's connected vehicles platform
SoftBank is getting into self-driving car services after the Japanese tech giant announced a joint-venture with Toyota in its native Japan.
Context & Ripple Effects
This joint venture is the second autonomous-car vehicle Toyota has built within months of its $2.8B Tokyo-based self-driving software company with two other Japanese firms — one stack for the driving itself, this one for the services layered on top. For SoftBank, it extends a mobility bet that already includes its 2016 strategic investment in Uber and a ride-hailing portfolio it was consolidating into the Vision Fund around the same time.
First-order effects
- SoftBank gains an operating foothold in Japanese mobility services rather than just equity stakes, pairing its IoT focus with Toyota's connected-vehicle platform; Toyota gets a capital partner already embedded in ride hailing through Uber and peers.
Second-order effects
- The venture puts pressure on Uber and other ride-hailing operators SoftBank backs — the investor now funds both the demand side (Uber, Ola, Grab, Didi) and a potential supply-side rival's service layer in Japan, sharpening conflicts as those stakes move into the Vision Fund.
Third-order effects
- Toyota is standardizing on a partner-per-layer structure — software via the $2.8B company, services via SoftBank, and later platform work with Waymo — suggesting incumbent automakers assemble autonomy from alliances rather than build it alone, a pattern that persisted through the 2025 Waymo-Toyota partnership.
The trend: Automakers are decomposing the autonomous car into stacked partnerships — software, fleet services, platforms — while capital investors like SoftBank position themselves across multiple layers at once.
