High-quality vehicles meeting a diverse range of applications

A next-generation ambulance released in 1992, the Toyota HIMEDIC “high-standard” ambulance, enjoys a leading share of the Japanese market as the first Japanese “high-standard” ambulance. We can respond to various special needs such as in providing support for medical advancements and regional characteristics with our small-lot production of a wide array of products.

History of trust over a long period of time

Our history of Conversion Business Unit started in 1955 when a used Simca was modified into a station wagon. In 1958, we built the first “microbus” in Japan, which went on to become a major hit product, thanks to vehicle concept and excellent usability.
Based on the technologies and experience as cultivated throughout our long history, we strive to further enhance customer trust.
