Introduction of the so-called "doshu-sei" system of reorganizing Japan into several regional blocs is the "ultimate structural reform" that will fundamentally change the nation's administrative, fiscal and political systems, Fujio Mitarai, chairman of the Japan Business Federation (Nippon Keidanren), told a recent symposium in Tokyo.

The system will redefine the roles of the central government and regional/local administrative bodies, and will enable rural Japan — which has long relied on support from national authorities — to regain vigor through its own strengths, the top business leader said.

Mitarai, also chairman of Canon Inc., gave the keynote speech to the Sept. 18 symposium organized by Nippon Keidanren and its public relations arm, Keizai Koho Center, under the title "Changing Japan through doshu-sei."
