Companies scrambled Tuesday to assess the damage after some manufacturing lines in Shizuoka Prefecture were automatically shut down following the strong earthquake in the Tokai region.
An official at Oji Paper Co. said the company's factory in Fuji that makes white paper boards for candy boxes automatically shut down after the magnitude 6.5 temblor.
Although some steam leaked from a broken incinerator pipe, no major damage that would interrupt production was found, the official said.
