Operations resumed Tuesday at four Toyota Motor Corp. plants in central Japan that were shut the previous day when parts deliveries were disrupted due to heavy snowfall last weekend. Meanwhile, other automakers' plants remain idled.

Toyota reopened its Takaoka, Motomachi, Tahara and Tsutsumi plants in Aichi Prefecture, where the company is headquartered.

On Monday afternoon, Nissan Motor Co. shut down one of the two production lines at its Tochigi plant. The company said the delay in parts delivery could affect the other line, as well as production at its Oppama plant in Yokosuka, Kanagawa Prefecture.

On Tuesday, Honda Motor Co. halted its Yorii plant in Saitama Prefecture, while Fuji Heavy Industries Ltd., maker of Subaru cars, suspended output at two plants in Gunma Prefecture.
