Sanyo has begun shifting production from a Japanese processor plant damaged in October's strong earthquake, as aftershocks continued to rumble through the area.
Spokesman Ryan Watson said Sanyo was moving production of some semiconductors for audiovisual products from the plant to two other factories in Japan.
Sanyo wouldn't say how much of its total production is accounted for by the damaged factory and how much is being moved, but it did say that 90% of the factory's chips were sold to other companies for use in their products.
The quakes killed 39 people, led to power cuts and halted production at several other high-tech plants in the area, although they have all restarted operations.
Aftershocks have continued for the last fortnight and there was another strong earthquake on Monday.
Sanyo couldn't say when production might restart in the damaged factory, partly because engineers had been unable to gain complete access. The company has kept people out of the plant because it has been unsure of the safety of the building.
