While it may appear that the United States is far ahead of Japan and the rest of the world in embracing e-business, the U.S. itself is a newcomer to the field, and tremendous challenges lie ahead, a U.S. business school educator told a symposium organized by Keizai Koho Center.

"This is not a world that we know of. It's not a world in which we've done business. So we are all just learning," said Daniel E. Costello, dean of Colorado State University.

Costello and 10 other educators at U.S. business schools took part in the symposium, which focused on e-commerce and Japanese and U.S. management styles, on the final day of a 10-day exchange program with Japanese business executives and government officials. The program included visits to the headquarters of NTT DoCoMo, Toyota Motor Corp., Matsushita Electric Industrial Co. and other leading firms.
