For nearly 50 years after post-World War II political reform, the Liberal Democratic Party (LDP) has enjoyed a monopoly over Japanese politics. Despite corruption scandals associated with party leaders and the economic recession of the 1990s, the LDP retains a majority of seats in the Diet and controls the Prime Minister’s office, held by LDP President Junichiro Koizumi. However, the results of the November 2003 general elections presage changes for the party system in Japan, as the LDP and its coalition partners managed only a slim margin over the Democratic Party. The election results have convinced many observers that Japan is finally on its way to a genuine two-party system. In fact, a viable political opposition to the LDP may be exactly what Japan needs to realize effective political and economic reforms.

The Japanese government has seen a gradual trend of increasing political competition and reform over the past decade. In post-war Japan, the LDP controlled the Diet without any major political opposition, due to the huge economic growth of the period. The turning point came in the elections of 1993, when a coalition of new parties formed by disillusioned LDP members, such as the New Party Sakigake and the Japan Renewal Party, ousted the LDP. Although the LDP quickly regained control of the Diet with the next election in 1996, the emergence of new parties forced it to enter coalitions to stay in power. In April 2001, the LDP responded to its declining popularity by holding primary elections for its party president for the first time. Junichiro Koizumi, who had remained with the LDP despite his image as a self-declared reformer, became the new LDP leader.

In light of these trends of waning LDP influence, the results of the November 10, 2003, general elections are a promising sign. The Democratic Party of Japan (DPJ), led by Naoto Kan, merged with Ichiro Ozawa’s Liberal Party, creating a large and visible opposition party. The DPJ also organized a policy-based challenge by creating a written “manifesto” of its proposals and timetables for reform, a first in Japan for a national election. This forced Koizumi to release his own reform agenda and brought policy issues to the center of political debate. The LDP emerged from the elections with 4 seats short of the 241 required for a majority presence in the Diet. With coalition partners, the LDP still controls the Diet, but the 177 seats won by the DPJ have weakened its hold. According to surveys conducted by the Yomiuri Shimbun, the DPJ was much more successful than the LDP at garnering the support of unaffiliated voters. The statistics suggest that the DPJ’s campaign provided a single rallying point for voters unhappy with the LDP.

While it is too soon to know if the DPJ will become a permanent political rival to the LDP, and thus create a two-party system, its presence will pressure the LDP into taking a tougher stance on many of the party’s internal problems. The LDP has repeatedly vowed to cut down on corruption and end the factional system, which leaves major decisions to a few leaders who control the votes of party members within their factions. With the DPJ as an alternative to voters, the LDP needs to fulfill its promises in order to stay in power. Already, Koizumi has begun to alter the system by picking a cabinet of young, pro-reform politicians rather than allowing his ministers to be determined by factional dynamics. Furthermore, the success of the DPJ’s pro-reform platform in attracting voters may convince LDP conservatives to support Koizumi’s economic policies, which include speeding up privatization and decentralization. He already has the backing of international investors—the value of the yen rose significantly when, on the day after the November 2003 elections, Koizumi promised to continue the policies that have increased investor confidence in Japanese business.

Although Koizumi’s relative popularity with the Japanese populace allowed him to retain the leadership of the LDP, his critics point out that he has had to compromise or abandon his campaign promises due to opposition from within his party. Party conservatives have grumbled that Koizumi has alienated their traditional constituencies in agriculture and small business by cutting down on public works projects and government subsidies. They see the election setbacks as proof that his reform agenda has not won favor with Japanese voters. And while the DPJ’s emergence as a major opposition party may be significant, Japan is still far from achieving a two-party system. In particular, the political inertia of the Japanese public is a huge barrier; they have continued to favor the LDP despite its scandals and factional politics. The average Japanese voter, especially in rural areas, still approves the LDP’s time-honored practice of passing legislation to help local constituencies.

Nonetheless, changes are afoot. If the pro-reform DPJ maintains its unity and becomes a viable opposition party, the LDP reformists in the Japanese government may finally find the impetus to effect political and economic reorganization.
