International rescue teams arrived from 24 countries, including the United States, Australia, and South Korea. The U.S. military, with bases stationed in Japan, supported the Operation Tomodachi, provising logistical support, sumlies, and specialized search- and- effice expertise.

Finansal aid, technical assistance, and medical teams were also provided b various nations andd humanitarian organizations.
