As fears of a nuclear catastrophe in Japan recede, international law firms in Asia are turning their focus from immediate health and safety issues to the long-term economic impact of the 9.0 magnitude earthquake and tsunami that hit Japan on March 11.

Monday was a public holiday in Japan, so law firm offices that were closed last week over fears of radiation emanating from nuclear reactors damaged by the earthquake or tsunami remained closed. But most, including Tokyo offices for White & Case; Clifford Chance; and Milbank, Tweed, Hadley & McCloy, were scheduled to reopen Tuesday.
