Leading Japan: The Role of the Prime Minister

Shinoda provides an analytical framework for examining the role of the prime minister in Japan's political decision making. He shows that two dimensions of fraction within the government and the ruling party—interagency rivalry and intraparty factions—confront the prime minister whenever a major policy issue needs to be resolved. Despite these obstacles, Shinoda shows that the prime minister can be effective.

First, Shinoda identifies the sources of power available to Japanese prime ministers—some from legal authorities and others from informal sources. Because prime ministers must rely on informal sources of power to effectively utilize institutional sources of power, their effectiveness varies depending on their background, experience, political skills, and personality. Shinoda identifies six major informal sources of power: power base within the ruling party, control over the bureaucracy, ties with the opposition parties, public support, business support, and international reputation. The national leader's leadership style can be defined depending on which sources of power they utilize in the policy process. He presents both successful and unsuccessful case studies—Hashimoto's administrative reform, Takeshita's tax reform, and Nakasone's administrative reform— illustrate how different prime ministers have succeeded or failed in applying their political resources. After examining these three case studies, Shinoda uncovers four types of leadership among Japanese prime ministers.
