The last dance of Just-in-Time?

A Tsunami struck Japan in March 2011 generating a collapse of Toyota supply chain. Starting in 2011, Toyota decided to completely revise its famous Toyota Production System and forced suppliers to hold a few months’ worth of inventory, threatening the entire philosophy of Just-in-Time. In 2015, Toyota was satisfied of its revised production system and ready to deal with future hits. Toyota didn’t know that the second biggest earthquake in the modern history of Japan would soon arrive.
