Occupation of Japan - Politics

Politics

Unlike the case in Germany Japan retained a native government throughout the occupation. General Horace Robertson of Australia, head of BCOF, wrote:

MacArthur at no time established in Japan what could be correctly described as Military government. He continued to use the Japanese government to control the country, but teams of military personnel, afterward replaced to quite a considerable extent by civilians, were placed throughout the Japanese prefectures as a check on the extent to which the prefectures were carrying out the directives issued by MacArthur’s headquarters or the orders from the central government.
The really important duty of the so called Military government teams was, however, the supervision of the issue throughout Japan of the large quantities of food stuffs and medical stores being poured into the country from American sources. The teams also contained so-called experts on health, education, sanitation, agriculture and the like, to help the Japanese in adopting more up to date methods sponsored by SCAP’s headquarters. The normal duties of a military government organisation, the most important of which are law and order and a legal system, were never needed in Japan since the Japanese government’s normal legal system still functioned with regard to all Japanese nationals ... The so-called military government in Japan was therefore neither military nor government.

The Japanese government's de facto authority was strictly limited at first, however, and senior figures in the government such as the Prime Minister effectively served at the pleasure of the occupation authorities before the first post-war elections were held. Political parties had begun to revive almost immediately after the occupation began. Left-wing organizations, such as the Japan Socialist Party and the Japan Communist Party, quickly reestablished themselves, as did various conservative parties. The old Seiyukai and Rikken Minseito came back as, respectively, the Liberal Party (Nihon Jiyuto) and the Japan Progressive Party (Nihon Shimpoto). The first postwar elections were held in 1946 (women were given the franchise for the first time), and the Liberal Party's vice president, Yoshida Shigeru (1878–1967), became prime minister. For the 1947 elections, anti-Yoshida forces left the Liberal Party and joined forces with the Progressive Party to establish the new Japan Democratic Party (Minshuto). 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. However, because of a heart failure Yoshida was replaced by Shinto in 1955.
