Takata Corp., Japan's largest maker of vehicle safety equipment, and Akebono Brake Industry Co. would lose the most among the country's auto parts suppliers should either General Motors Corp. or Chrysler LLC declare bankruptcy, according to Moody's Japan K.K.
The companies get at least 20 percent of their sales from Detroit automakers, Moody's analyst Jun Sakurabayashi said.
This puts them at the most risk from a collapse by a U.S. carmaker among the six Japanese suppliers covered by the credit-rating company. In contrast, Toyota Motor Corp. affiliate Denso Corp., the world's largest listed auto supplier, gets about 7 percent of its sales from the U.S.
