Constitution
The current constitution was approved by Japan in 1947, this document aimed to address the weaknesses of the previous Meiji Constitution and lay the foundation for a vibrant democracy in Japan. Its key features include:
* Sovereignty of the People: According to the constitutions, the sovereignty rests with the people.
* Democratic institutions: The constitution reinstated democratic institutions that had flourished under Taisho democracy.
* Expanded Suffrage: The constitution of 1947 expanded suffrage to women guaranteeing equal rights for men and women.
* Parliamentary system: Japan adopted a parliamentary system of government, maintaining a lower house and an upper house, similar to its previous democratic experiences during the Taisho era.
* Labor rights: It introduced Western-type labor practices, including a clause that declared the right to collective bargaining.
* Peace clause: The article 9 of the constitution renounces war and prohibits the threat or use of force as means of settling international disputes.

of this current document has been widely viewed by many geopolitical analysts and historians as one that
was forced upon Japan by the United States after the
end of World War II.
Although this "imposition" claim arose originally as a rallying cry among conservative politicians in favour of constitutional revision in the 1950s, and that it wasn't "inherently Japanese", it has also been supported by the research of several independent American and Japanese historians of the period.
A competing claim, which also emerged from the political maelstrom of the 1950s revision debate, holds that the ratification decision was actually the result of apparent "collaboration" between American occupation authorities, successive Japanese governments of the time, and private sector "actors".

Policy making
Despite an increasingly unpredictable domestic and international environment, policy making conforms to well established postwar patterns. The close collaboration of the ruling party, the
elite bureaucracy and important interest groups often make it difficult to tell who exactly is responsible for specific policy decisions.
Policy development in Japan
After a largely informal process within elite circles in which ideas were discussed and developed, steps might be taken to institute more formal policy development. This process often took place in deliberation councils (''shingikai''). There were about 200 ''shingikai'', each attached to a ministry; their members were both officials and prominent private individuals in business, education, and other fields. The ''shingikai'' played a large role in facilitating communication among those who ordinarily might not meet.
Given the tendency for real negotiations in Japan to be conducted privately (in the ''
nemawashi'', or root binding, process of consensus building), the ''shingikai'' often represented a fairly advanced stage in policy formulation in which relatively minor differences could be thrashed out and the resulting decisions couched in language acceptable to all. These bodies were legally established but had no authority to oblige governments to adopt their recommendations. The most important deliberation council during the 1980s was the Provisional Commission for Administrative Reform, established in March 1981 by Prime Minister
Suzuki Zenko. The commission had nine members, assisted in their deliberations by six advisers, twenty-one "expert members," and around fifty "councillors" representing a wide range of groups. Its head,

president
Doko Toshio, insisted that the government agree to take its recommendations seriously and commit itself to reforming the administrative structure and the tax system.
In 1982, the commission had arrived at several recommendations that by the end of the decade had been actualized. These implementations included tax reform, a policy to limit government growth, the establishment in 1984 of the Management and Coordination Agency to replace the Administrative Management Agency in the Office of the Prime Minister, and privatization of the
state-owned railroad and telephone systems. In April 1990, another deliberation council, the Election Systems Research Council, submitted proposals that included the establishment of single-seat constituencies in place of the multiple-seat system.
Another significant policy-making institution in the early 1990s was the
Liberal Democratic Party

's Policy Research Council. It consisted of a number of committees, composed of LDP Diet members, with the committees corresponding to the different executive agencies. Committee members worked closely with their official counterparts, advancing the requests of their constituents, in one of the most effective means through which interest groups could state their case to the bureaucracy through the channel of the ruling party.

For the

Democratic Party (Minshutō). This divisiveness in conservative ranks gave a plurality to the Japan Socialist Party, which was allowed to form a cabinet, which lasted less than a year. Thereafter, the socialist party steadily declined in its electoral successes. After a short period of Democratic Party administration, Yoshida returned in late 1948 and continued to serve as prime minister until 1954.
