Heavy rain and flooding that inundated western parts of the country over the weekend has forced some manufacturers in the region to suspend operations, and impeded usual business activities on Monday.

Panasonic Corp. said one of its factories in Okayama Prefecture, one of the hardest-hit areas, halted operations due to flooding on its manufacturing floors.

The electronics-maker said it is still unclear whether they will be able to resume usual operations on Tuesday, although the water on the floors had mostly subsided by later on Monday.
