General Headquarters, Supreme Commander for the Allied Powers
In August 1945, Japan accepted the Potsdam Declaration and decided to surrender in World War II.
On September 2, representatives of the Japanese government signed the Instrument of Surrender aboard the USS Missouri in Tokyo Bay, after which Japan was placed under Allied occupation until 1952.
The central entity for implementing this occupation policy in Japan was the Supreme Commander for the Allied Powers (SCAP) and its headquarters, the General Headquarters (GHQ).
Generally, the entire organization is often referred to as " GHQ " or " GHQ / SCAP ".
The position of Supreme Commander was assumed by Douglas MacArthur of the United States Army.
GHQ was a headquarters established for military occupation, but its scope of activity was not limited to military matters; it implemented occupation policies related to a wide range of Japan's national and social systems, including politics, administration, economy, education, labor, agriculture, media, and the constitution.
1945 | Japan's Surrender
On July 26, 1945, the United States, the United Kingdom, and China issued the Potsdam Declaration to Japan. The declaration outlined basic conditions for post-war Japan, such as the unconditional surrender of the Japanese military, disarmament, punishment of war criminals, the revival and strengthening of democratic tendencies, and the respect for fundamental human rights.
The Japanese government decided to accept the Potsdam Declaration on August 14.
On August 15, the Imperial Rescript on the Termination of the War was broadcast by Emperor Showa.
On August 30, MacArthur, who had been appointed Supreme Commander for the Allied Powers, arrived.
On September 2, Japan's surrender was formally finalized by the signing of the Instrument of Surrender.
Supreme Commander for the Allied Powers
SCAP refers to the position of Supreme Commander for the Allied Powers
Supreme Commander for the Allied Powers .
The first Supreme Commander, MacArthur, served as SCAP from 1945 to 1951. In April 1951, after Harry S. Truman dismissed MacArthur, Matthew Ridgway became the successor as Supreme Commander for the Allied Powers and served as SCAP until the end of the occupation in 1952.
GHQ
SCAP The headquarters that actually planned, coordinated, and implemented occupation policies under General Headquarters GHQ .
GHQ was located in Tokyo, and the headquarters of MacArthur is particularly well known as the Dai-ichi Seimei Building near the Imperial Palace.
GHQ contained not only military departments but also numerous specialized sections responsible for politics, economy, education, and more.
Organization of GHQ
Specialized sections were established for each policy area.
Government Section
The Government Section (GS) was responsible for political and administrative systems. The central department that drafted the GHQ proposal during the process of enacting the
Constitution of Japan was also the Government Section.
Economic and Scientific Section
The Economic and Scientific Section (ESS) was responsible for policies concerning the Japanese economy. It was a department that played an important role in the economic system reforms of postwar Japan.
Civil Information and Education Section
The Civil Information and Education Section (CIE) was responsible for education, culture, religion, information, and more. It also played a central role in postwar educational system reforms.
Public Health and Welfare Section
The Public Health and Welfare Section (PH&W) was responsible for public health and social welfare. In Japan immediately after the war, problems such as food shortages, housing shortages, and infectious diseases existed, and public health policy was also an important field of occupation administration.
Did they rule Japan directly?
GHQ What is important for understanding the relationship with the Japanese government. In Germany, the Allied powers divided the region and occupied it, and there was a large portion directly ruled by the Allied side, but a different method was adopted in Japan. Japan's existing state apparatus was basically maintained, and as a general rule for occupation policy,
indirect rule was adopted, in which policies were implemented through the Japanese government.
SCAPIN
GHQ Important directives issued from SCAPIN (Supreme Commander for the Allied Powers Instructions) are called.
Specific occupation policies were instructed to the Japanese government by SCAPIN. The Japanese government responded by preparing laws, cabinet orders, ministerial ordinances, and administrative measures to implement actual policies, and
administration by the Japanese government and occupation policy by GHQ existed in an overlapping manner.
Demilitarization
One of the most important policies in the early stages of the occupation was the demilitarization of Japan. The Japanese military was disbanded, the Ministry of War and the Ministry of the Navy were abolished, the munitions industry was reorganized, and the repatriation of Japanese military personnel and civilians who were overseas was carried out on a large scale. In addition, a purge of public officials involved in war leadership was also implemented.
International Military Tribunal for the Far East
In 1946, the International Military Tribunal for the Far East (Tokyo Trial) began. The Allied powers prosecuted Japan's war leaders, the trial continued until 1948, and Hideki Tojo and others were found guilty. The
Tokyo Trial was conducted during the occupation period by GHQ, but the trial itself was carried out by the International Military Tribunal composed of 11 Allied nations.
Political System Reform
Under the occupation, major changes were also made to Japan's political system.
Through electoral reform, women's suffrage was realized.
In the April 1946 general election for the House of Representatives, women voted in a national election in Japan for the first time, female members of the Diet were born, and the local autonomy system was reorganized.
In addition, changes were made to laws and systems related to the pre-war political system, such as the abolition of the Peace Preservation Law.
Constitution of Japan
GHQ and the postwar period in Japan, what is particularly important to understand is the involvement in the enactment of the Constitution of Japan. After the end of the war, the Japanese government began the work of revising the
Constitution of the Empire of Japan, and the Constitutional Problem Investigation Committee, centered on Joji Matsumoto, examined the draft amendment, but GHQ judged the Japanese government's proposal to be insufficient.
In February 1946, the GHQ Government Section created its own draft constitution ( GHQ Draft ), and the Japanese government used this as a basis to draft and revise it on the Japanese side, submitted the constitutional amendment bill to the Imperial Diet, and after deliberation and revision in the Imperial Diet, the Constitution of Japan was promulgated on November 3, 1946, and came into effect on May 3, 1947.
Land Reform
One of the representative economic and social reforms of the occupation period was land reform. In the reform, a policy was promoted in which the government purchased farmland from landlords and sold it to tenant farmers, etc., which led to a significant increase in owner-farmers and was a reform that greatly changed the land ownership structure of rural villages.
Zaibatsu Reform
In the early stages of the occupation, reforms were also promoted for the zaibatsu, which had a major influence on the Japanese economy; the Holding Company Liquidation Commission was established, and the dissolution of corporate control structures centered on holding companies such as Mitsui, Mitsubishi, and Sumitomo was promoted.
The Antimonopoly Act was also enacted.
Labor Reform
Reforms were also carried out regarding the labor system.
The Trade Union Act in 1945, the Labor Relations Adjustment Act in 1946, and the Labor Standards Act in 1947 were enacted, and new legal systems were established regarding labor conditions.
Fundamental labor rights were also stipulated in the Constitution of Japan.
Educational Reform
The pre-war education system was also reorganized, and a school system based on the 6-3-3-4 system was introduced, and the Fundamental Law of Education and the School Education Act were enacted in 1947.
Compulsory education became nine years, consisting of six years of elementary school and three years of junior high school.
Reforms were carried out in a wide range of areas, including educational administration, the school system, and textbook content.
Media and Censorship
GHQ promoted democratization policies, but during the occupation, it also implemented censorship of newspapers, publishing, broadcasting, etc., and GHQ had censorship organizations such as the Civil Censorship Detachment (CCD) within it.
Criticism of occupation policy, specific information regarding the Allied Powers, reports related to the occupation forces, and other content judged to be problematic for occupation policy were subject to censorship.
Was GHQ the American government?
GHQ / SCAP was composed mainly of the U.S. military, the Supreme Commander was also American, and the influence of the U.S. government was very significant in actual occupation policy.
However, in terms of the system, SCAP is not simply a "Japanese branch of the U.S. government."
As the name suggests, the occupation of Japan was institutionalized as an occupation by the Allied Powers.
Occupation administration by the Allied Powers
In addition to GHQ / SCAP, there were international organizations involved in the occupation of Japan.
Representative examples are the Far Eastern Commission (FEC) and the Allied Council for Japan (ACJ). Multiple Allied nations, including the United States, the United Kingdom, the Soviet Union, and China, participated in the Far Eastern Commission and handled basic policies regarding the occupation of Japan.
The Allied Council for Japan was located in Tokyo, and representatives from the United States, the Soviet Union, China, and the British Commonwealth participated.
Cold War
GHQ While the occupation continued, the global situation itself changed. The conflict between the United States and the Soviet Union, which had been on the same Allied side during
World War II, deepened, and the Cold War was formed. In 1949, the People's Republic of China was established. In 1950, the
Korean War began.
Changes in Occupation Policy
In the early stages of the occupation, demilitarization, democratization, and political and social institutional reform were the main pillars. Later,
economic recovery, political stability, and responses to communism became more emphasized.
This shift in occupation policy is generally called the Reverse Course, and changes were also made to some of the initial policies, such as the dissolution of the zaibatsu and the purge of public officials.
1950 | National Police Reserve
In June 1950, the Korean War began. Many of the American troops stationed in Japan moved to the Korean Peninsula. Subsequently, by order of
MacArthur, the Japanese government established the National Police Reserve.
The National Police Reserve was later reorganized into the National Safety Force, and in 1954, the Self-Defense Forces were established. This movement also becomes an important event for understanding the international situation in the latter half of the occupation and the changes in Japan's security system.
1951 | Dismissal of MacArthur
In the Korean War, which began in 1950, MacArthur also served as the Commander of the United Nations Command. The conflict between
MacArthur and the Truman administration deepened over war policy. On April 11, 1951,
President Truman relieved MacArthur of all military duties, and with this, MacArthur's approximately 5 years and 8 months of service as Supreme Commander in Japan also ended. Ridgway succeeded him as SCAP
.
San Francisco Peace Treaty
On September 8, 1951, the
Treaty of Peace with Japan was signed between Japan and the Allied nations, and it came into effect on April 28, 1952. The state of war with the Allied nations legally ended, Japan regained its sovereignty, and the Allied occupation of Japan also ended.
1952 | End of GHQ
On April 28, 1952, with the entry into force of the San Francisco Peace Treaty, the
GHQ/SCAP occupation of Japan ended. For approximately 6 years and 8 months from 1945,
GHQ finished its role as a temporary governing body established for the special situation of occupation.
Archive Point
GHQ / SCAP was the central organization that implemented Allied occupation policies in Japan from 1945 to 1952 following World War II. The position of Supreme Commander was held by two individuals:
Douglas MacArthur and Matthew Ridgway. Although
GHQ was established as a military headquarters, its activities were not limited to military matters but covered a wide range of Japan's national and social systems. The occupation method was based on indirect rule, where the Japanese government itself was not abolished, and occupation policies were not consistent, with their focus shifting due to the
Cold War and changes in the East Asian situation. GHQ / SCAP
was the governing body that existed to implement occupation policies locally during the period when Japan was under Allied occupation.
