Tesla has begun supporting the conversational AI Grok in its vehicles in Japan, with the rollout announced by Tesla Japan on its official X account. The feature is available on vehicles running software version 2026.20 or later and requires a Premium Connectivity subscription, with an English help page also noting Wi-Fi as an option. The beta does not require a separate Grok account or additional fees as of July 10, but it does not support vehicle control functions such as climate or media.
