Japan needs to keep up the momentum of economic reforms and accelerate them in the face of long-term challenges such as an aging population and increased global competition, scholars from U.S. business schools said at a recent symposium in Tokyo.

Some of the scholars expressed concern that Japan could become complacent with the level of its recovery in recent years -- aided much by the China boom -- and delay necessary reforms.

The scholars were speaking on the theme, "Sustainability of the Japanese Economy" at the June 3 symposium, organized by Keizai Koho Center at Keidanren Kaikan. The event followed a weeklong program marked by the scholars' exchanges with Japanese scholars, businessmen, and government officials.
