Books on Japan that are worth reading must fulfill three criteria. They must be based on a direct access to primary sources, which presupposes a high degree of familiarity with the Japanese language and social history. They have to build upon the scholarly literature, including analysis and commentary presented by Japanese scholars. And they have to offer a theoretical perspective that is relevant to the subject under consideration.
The Logic of Japanese Politics meets these three criteria with a wide margin. Professor Curtis seems to know every major political figure firsthand and has developed with many of them a personal relationship since their rookie years as junior Diet members. As a distinguished political scientist, he brings intellectual breadth as well as historical depth to his topic, and has himself published extensively in Japanese. He is careful not to placate preconceived notions on the Japanese political system, and develops useful comparisons with politics in Europe (whereas most observers, including Japanese political actors, tend to overuse the comparison with US politics).
The 1990s was an important turning point for Japanese politics. From 1989 to 1998, Japan had nine prime ministers; there had been only eleven over the previous thirty-four years. From 1955 to 1993, only one party, the LDP, was in power at the national level. Then during one year beginning in August 1993, every party in the Diet except for the Communists participated in one coalition government or another. Among parties opposed to the LDP, affiliations were in such a flux that a number of Diet members stopped indicating their party membership on their name cards. Although the PLD's absence from power lasted for less than a year, before they returned to government in an alliance with their former arch-rival the Japan Socialist Party, the period marked a dramatic rupture in Japanese politics, with the end of the so-called '55 system and the quest for a new political landscape that took some time consolidating.
Each chapter focuses on a particular phase of this transition: the ouster of the LDP from government and its replacement by a seven-party coalition led by the charismatic prime minister Morihiro Hosokawa; the unraveling of this coalition that nonetheless achieved to pass an important electoral reform; the LDP's return to power in a coalition led first by the Socialist Party's chairman Tomiichi Murayama, then by former MITI minister Ryutaro Hashimoto; the disappointing results of the 1998 upper-house election and the appointment of Keizo Obuchi over Junichiro Koizumi as party chairman and head of government.
The result of these changes and reorganization was immobilism and confusion precisely at a time when Japan needed policy change and strategic direction in order to deal with an ailing economy. Despite the rhetoric on the need for political reform, administrative restructuring and deregulation, Curtis shows that the Japanese public felt ambivalent toward undoing the system that brought Japan its postwar success, and that the authorities delivered relatively little in terms of real departures from the past. He also castigates the Japanese's infatuation with the idea that the two-party system of Westminster democracy would magically cure Japanese politics from all its ills, arguing instead that the "rice-roots" quality of Japanese democracy is its strength rather than its weakness.
Distinctly Japanese political institutions are introduced throughout the text. The zokugiin is a Diet member who concentrates on a single issue, developing expertise and influence through his contacts with the bureaucracy and special interest representatives. The habatsu is a faction within the LDP bound together by ties of personal allegiance more than doctrinal content. The most powerful faction usually leaves the position of party president (and thus prime minister) to someone from another faction, while exercising power from the shadow through control of the post of party secretary-general and through controlling the composition of the prime minister's cabinet. The all-important secretary-general has final say on candidate nominations and is in charge of the party's funds, two sources of power that enable him both to do favors and to punish party members.
The kokutai or kokkai taisaku iinkai is a party's Diet-strategy committee that doubles the formal House Management Committee (giin unei iinkai, or giun) and that offers the channel for backroom deals between parties or for informal contacts with the bureaucracy. The innai kaiha is a parliamentary caucus that can be distinct from the political party (or parties) it supports. It came to play a critical role after the collapse of LDP one-party dominance in 1993 as politicians seeked to restructure the party system.
Detailed knowledge of the functioning of these institutions and others is important in order to understand how politicians operate within particular institutional constraints. Politics in Japan makes sense in Japanese terms, and clear reasoning can make sense of Japanese politics.
