1997 Aisin fire
The 1997 Aisin fire is the fire that shut down one of the production facilities of the Toyota-subsidiary Aisin Seiki Co. on February 1, 1997, a Saturday. The event was notable as the factory was the main supplier of a motor part for Toyota cars. Due to the just in time stock keeping philosophy of the Toyota Production System (TPS), Toyota's car factories reportedly only kept four-hour stocks of the part.
However the event also provided an example of successful business relationships between Toyota and its suppliers, allowing the company to quickly manufacture replacement parts and limit the halt in production of its cars, thereby minimizing the losses from this event.
