Japan's Toyota Motor Corp. will resume partial production Tuesday at its domestic plants, Kyodo News reported on Monday.

The world leading automaker, as well as other Japanese automobile manufacturers, decided on last Wednesday to suspend all their production as last Monday's major earthquake in Niigata Prefecture seriously damaged the auto parts supplier Riken Corp.'s factory located there.

Riken is Japan's leading producer of piston rings for automobile engines. Due to the damage in the magnitude 6.8 earthquake, some 50 auto plants in Japan have been temporarily closed, affecting some 80 percent of domestic production activities, according to the Japan Automobile Manufacturers Association.

Production cutbacks by the twelve automakers are expected to amount to more than 40,000 vehicles, including 26,000 at Toyota, 2,000 at Honda and 10,000 at Suzuki.
