Toyota and Honda launch disaster road maps after Kumamoto earthquake

On July 28, 2026, a magnitude‑7.1 earthquake struck Kumamoto Prefecture, registering a maximum intensity of 7. In the aftermath, Toyota Motor Corp. and Honda Motor Co. each released online maps showing roads that had been traversed by their vehicles in the previous 24‑48 hours.

Toyota’s “Passable Route Map” integrates vehicle probe data, traffic‑restriction information and its proprietary T‑Probe congestion data to display real‑time passable roads around the affected area. Honda’s “Travel Record Information Map” presents similar vehicle‑derived routes to aid navigation. Both services note that displayed roads may still be subject to official traffic controls and are not guarantees of accessibility.

The maps are part of a collaborative effort that began in September 2025 between Toyota, the Toyota Mobility Fund and Kumamoto Prefecture to improve rapid response and recovery through shared data, a project slated to continue through March 2026.
