However, a large portion of Toyota vehicles and parts are still manufactured in Japan for both the Japanese-domestic as well as international markets.. Some Toyota parts may also be manufactured or sourced from third-party suppliers that specialize in specific components or materials. Ultimately, the exact location of production can vary depending on factors such as production capacity, strategic sourcing decisions, and demand. To get specific part locations or origin, a reference to Toyota's manufacturing facilities and supplier network information would be required.
