Foreign firms set up evacuation plans in Tokyo and parts of northern Japan on Tuesday in a bid to distance staff from a quake-crippled nuclear plant while keeping their businesses running.

The planned exodus was already under way for several companies and involved both expats and Japanese workers. Others were still monitoring events. Some reported employees were opting to stay put despite concerns about their safety.

Swedish truckmaker Volvo was also holding back even though its Tokyo plants employing 4,000 are closed and some of its foreign staff have left the country of their own accord.

Continental , the German tyre and autoparts maker, said it was preparing to evacuate around 100 non-Japanese employees and their families by Wednesday, and that Japanese employees would be brought from insecure regions to Hiroshima where lodgings for as many as 400 had been organized.
