Since last August 31, defeated the Liberal Democratic Party Democratic Party of Japan for the first time, to seize power through elections, began to try "from the official primary politics to democracy," the change. But after nearly 8 months "trial and error stage," the Democratic Party, one of the three power problems have not been resolved, but more and more serious conflicts within the party fully exposed until the cause Hatoyama resigned.

First, the political and administrative problems inherent in the Democratic Party advocates a "politician-led policy" embarrassing situation. After taking office, the Democratic Party stands for "shake off dependence on bureaucratic" decision-making system, adhere to the Minister, the Deputy Minister and the Chief Officer and other "politicians" leading policy. But the reality is that the Democratic Party, elected in the first elected "first year" a high proportion of members, lack of political experience, is difficult to quickly form a policy. The core strength of the traditional decision-making - all government departments of the Ministry, to consider official, Board, Director and other "cadres" or away from the policy center, or stand by and see him fail. The Democratic Party's "politicians" and bureaucrats did not establish a political understanding, directly affect the effective formation of the Democratic Party policy. The face of the global financial crisis, economic decline, the Democratic Party failed to introduce effective measures, slow Japan's economic recovery, rising discontent.

In particular, the Democratic Party is holding a "political leadership", "national decisions" build "genuine democracy" banner came to power, but have not yet made clear the "National Development Strategy", the political trend is unknown. The Hatoyama and Ozawa's political capital is unknown, gave the Democratic Party's "clean" image of wiping the black. The face of the Senate election, the power structure of Japan's political parties mutation, Congress and political mechanics more complex, conflicts within the Democratic Party increased, decreased self-confidence, power situation deteriorated.

Secondly, the post-crisis economic performance more difficult. Despite the crisis more than the past year and a half, but the Japanese economy did not recover to pre-crisis levels. Unemployment is high, the potential increase of unemployment; and national measures to reduce taxes in the situation, Japan has topped the corporate tax rate in developed countries. In particular the tendency of the Democratic Party's policy of operating trade unions, large enterprises, the backbone of enterprises forced to seek opportunities abroad, capital outflows, the hollow of the domestic industry more seriously. In the face of Japan's aging population, expansion of social security expenditure, government debt more than 2 times more than GDP, unsustainable fiscal expansion route. In this context, increasing business failures, "the enterprise unemployment" began to pour into the community to form a new social pressures.

Other hand, the Democratic Party convention in the election emphasized the "birth, education subsidies," "farm subsidies", "highway free" as promised, or discount, or canceled, the Democratic Party political broken promises to support the rate of power of the beginning of more than 70%, or nearly 20%.

In the face of numerous challenges and national governing disappointment, increased conflict within the Democratic Party, asked Hatoyama growing political pressure to resign. In particular, the eve of Hatoyama resigned because of the ruling coalition Social Democratic opposition in the base Hatoyama policy concessions, the party was dismissed the first minister post, out of the cabinet, causing the Social Democratic Party and Democratic Party have become enemies, the joint power system collapse. The opposition parties, the beginning of the year, the Liberal Democratic Party "self surgery", to engage in "bad debt peel" like a new party realignment, and combined with local forces in the New Party, formed the party politics of Japan's "third pole" strength. The Senate in July to face the general election, the party does not rule out these new forces of political frustration with the Democratic Party united to launch joint offensive.

The financial crisis, the global economic turmoil, unstable security situation in East Asia back many hidden dangers, contradictions complex. As a region with the greatest economic strength of Japan, how to maintain political stability, economic recovery, probably will be directly related to economic, political and even security and stability.
