TOKYO, Jan 6 (Reuters) - Toyota Motor Corp 7203.T plans to halt production at all of its plants in Japan for a total of 11 days in February and March in response to flagging auto sales, Japanese public broadcaster NHK reported on Tuesday.

The automaker in November cut its production plan by 950,000 units for the business year ending in March, but the firm now eyes a deeper reduction given a further deterioration in car sales, NHK said.

Toyota, which already announced a three-day suspension at all of its factories in Japan this month, plans the additional production halt for the next two months to reduce inventories, the broadcaster said. (Reporting by Taiga Uranaka; Editing by Chris Gallagher)
