Toyota Motor Corp. said Monday its disrupted operations should be fully back to normal on Thursday, as its transmission factory in Hokkaido where a powerful earthquake halted work last week was set to resume production some time after 8:30 p.m. Monday.

The shutdown of the transmissions factory in Tomakomai, in southwest Hokkaido, had interrupted production at 16 of Toyota's 18 domestic assembly plants Monday.

But the auto giant said later in the day that with the production of transmission parts now certain, operation of other plants will return to normal Thursday.

The magnitude 6.7 earthquake early last Thursday morning killed dozens of people and temporarily cut off power across the island. Power was restored to Toyota's transmissions plant Saturday and production facilities are being checked for a restart, Toyota said.
