The business environment surrounding U.S. companies has changed and they are looking for ways to not only survive, but thrive against severe competition.

Four U.S. business school lecturers presented a series of lectures on their research of U.S. businesses at a symposium titled "Corporate Competitiveness from the International Viewpoint," organized by the Keizai Koho Center in Tokyo on May 30.

Each lecturer delivered their presentation before taking part in a panel discussion.
