Toyota's Tohoku arm warehoused molds and parts at suppliers free — a JFTC first

Toyota Motor East Japan, the Toyota group's production company for the Tohoku region, commissions engines, transmissions and complete cars from a network of small parts makers. On October 31, 2025, the Japan Fair Trade Commission issued a recommendation against the company for violating the Subcontract Act by making suppliers warehouse its property at no charge — the first time the JFTC took that step against a completed-vehicle maker over free mold storage.

The conduct had two layers. From April 2024 to March 2025, the company left 440 supplier-owned molds and jigs untouched at ten subcontractors while refusing to let them discard anything without its consent. Separately, its bulk-production system for service parts ordered one final large batch of parts past their production peak, set no delivery deadline, and let the finished parts sit at seven suppliers until individual customer orders trickled in — 777 parts warehoused free from August 2023 to March 2025.

The JFTC also issued formal guidance for refusing to take delivery of those same 777 parts until each was ordered — the second violation on the same stock — and took the unusual step of filing a request with parent Toyota Motor Corporation itself: the group's own manufacturing manual was identified as a major cause of both practices, and the parent was asked to revise it.

Ten to twelve subcontractors stored 440 molds and 777 finished service parts unpaid; Toyota East Japan paid ¥10.35M in storage fees and part costs.

Affiliate purchasing staff follow central group manuals; a template that bans discarding molds and orders nothing until needed reproduces the violation at every subsidiary that copies it.

Finished-goods storage shifts costs quietly: no invoice is disputed and no fee is charged — the burden migrates onto suppliers' balance sheets as dead stock and warehouse space.

Service-parts demand forecasting is genuinely hard, which made indefinite free storage at the supplier feel like normal operations rather than a unilateral cost transfer.

Suppliers could not push back: the buyer controlled future orders, and discarding a mold without consent risked losing the account entirely.

A powerful buyer can turn its inventory costs into a quiet tax on small suppliers just by not ordering and not collecting. One central manual made a dozen suppliers free warehouses at once.

By the time of the recommendation Toyota East Japan had already paid ¥9,415,337 — the cost-equivalent of the free storage — to subcontractors on May 30, 2025, plus ¥931,032 for the 777 undelivered parts. It confirmed board resolutions, ran Subcontract Act training for ordering staff and notified affected suppliers. The JFTC asked parent Toyota Motor to review the group manual; Toyota said it was already studying improvements. It was the first completed-car maker ever recommended over free mold storage, in an enforcement wave that has hit some 30 Japanese manufacturers.
