This book seeks to explain how politics actually operates in the Japanese Diet using the author s bilayer theory or dual power structure theory. It is about how politics in Japan operates behind closed doors and how laws are actually made in the Diet. While some parts of the process remain hidden-subterfuge is inherently part of politics-the author uses interviews with party officials current and former kokkai taisaku-inkai committee members of all parties in the Diet to elucidate the process as much as possible.
