TOKYO (Reuters) - Toyota Motor Corp said it had canceled the day shift at three factories in northeastern Japan due to heavy rains that earlier on Friday burst the banks of a river in the city of Osaki, in Miyagi prefecture.

There has been no damage at the facilities - two in Miyagi and one in neighboring Iwate prefecture - which are run by its subsidiary Toyota Motor East Japan, a spokeswoman said.

Toyota will decide whether it will resume operations for the evening shift by around noon, she added.
