The Walt Disney Co. has donated $2.5 million to the American Red Cross to support humanitarian aid efforts connected to the earthquake and tsunami that has devastated northern Japan.

Disney said Tuesday it will match donations by its employees to the Red Cross Japan Earthquake Fund, the Pacific Tsunami Fund and Save the Children, up to a total of $1 million. The Mouse is invested in the Japanese market through the Tokyo Disneyland and DisneySea theme parks, among other ventures.

“Our hearts go out to the people of Japan,” said Disney prexy-CEO Robert Iger.

U.S. corporate donations to Japanese relief funds come amid increasing global concern about the possibility of a severe nuclear accident resulting from reactors damaged by the earthquake and tsunami that caused untold destruction along the Japanese coastline last week.

Sony Corp. earlier made a donation of about $3.6 million to the Central Community Chest of Japan charitable org, and it is instituting a matching donations program for its employees. The electronics giant has also made available 30,000 radios for emergency use.

NBCUniversal’s internal Asian Pacific Americans Affinity group will hold fund-raisers on March 23 at restaurants in New York, Los Angeles and San Francisco.
