According to estimates from a study conducted by Teikoku Databank, as of November 2024, there were a total of 68,485 supply-chain companies in Japan’s automotive industry for 10 automakers.

Toyota has the largest number of suppliers, at 40,680 companies, followed by Honda with 22,465 and Nissan with 19,084. The breakdown of supply-chain companies for Toyota shows that 2,306 were categorized as Tier 1, meaning that they do direct business with Toyota; meanwhile, there were 22,334 Tier 2 companies that engage in direct business with Tier 1 companies. In addition, there were 16,040 other companies categorized as Tier 3 or beyond. For all automakers, Tier 2 was the largest segment among supply-chain companies.

Simply adding up the number of supply-chain companies listed here for the 10 manufacturers gives a total of 147,207, which is more than double the actual total of 68,485 companies. As some companies utilize the same suppliers, they are counted more than once.

There are 9,242 companies that operate within the supply chain of both Honda and Nissan, and 3,472 companies that are suppliers to those two companies and also to Mitsubishi Motors.
