Japanese automakers are facing a double whammy of global chip shortages and inflated raw material costs, derailing production plans and offsetting the extra profits gained from a weak yen.

Although the earnings of some major carmakers for the April-September period showed that many have benefited from the historically weak yen, they now appear to be more cautious than upbeat.

Automakers are concerned that they won't be able to manufacture enough vehicles to meet demand due to a shortage of chips and the high commodity prices that are watering down the benefits of the depreciated Japanese currency.
