Toyota Motor Corp. said Friday it expects group operating and net profit for the current business year to drop more than 30 percent from the previous year after the March 11 earthquake and tsunami damaged key parts makers in northeast Japan.

For the year to next March, Toyota expects to make a group operating profit of ¥300 billion, down from ¥468.2 billion a year ago, and a net profit of ¥280 billion, down from ¥408.1 billion.

But it also expects to generate ¥18.6 trillion in sales, down slightly from ¥19 trillion last year.
