If the US automotive industry has one takeaway from the tsunami in Japan last March, it’s this: be prepared.

The disaster, and subsequent flooding in Thailand, dramatically affected the vehicle and supply chain in Asia – and not just for Japanese automakers. General Motors, Ford, and Chrysler also rely, although to a lesser extent, on certain supply components from Japan. The tsunami forced all three companies to establish contingency plans for where to get materials such as paint dye or computer chips for navigation systems if disaster strikes again.

“What [the tsunami] did was show the vulnerability in the supply chain. It became clear automakers had no idea how far down the supply chain some of these third level suppliers were. They now have a process in place to set up a war room to handle these situations,” says Michele Krebs, a senior analyst with

Of course, the hardest hit were Japanese automakers, all of which suspended vehicle production for several weeks. Even though most auto assembly plants in Japan operate south of Tokyo – an area not affected by the tsunami – the majority of its assembly suppliers are located north of Tokyo, directly in the eye of the disaster. 

The Japanese automakers first felt a sales hit last summer, when their collective US market share fell. By June 2011, the Detroit Three controlled 50 percent of the US market, according to, about 4 percentage points more than it did one month before the tsunami.

Auto buyers who may have been considering fuel-efficient bestsellers like the Honda Fit or Toyota Prius were faced with having to wait several months before getting the car. The delay may have forced them to reconsider and purchase domestic equivalents like the Ford Focus, Ford Fusion, or Chevrolet Cruze.
