At the end of the
Second World War, 'Japan was occupied' by the
Allied Powers, led by the
United States. This was the first time since the unification of
Japan that the island nation had been occupied by a foreign power. The
San Francisco Peace Treaty, signed on
September 8,
1951, marked the end of the Allied occupation, and when it went into effect on
April 28,
1952, Japan was once again an independent state.
Surrender

Japan
initially surrendered to the Allies on
August 14,
1945, when Emperor
Hirohito accepted the terms of the
Potsdam Declaration. On the following day, Hirohito announced Japan's surrender on the radio. It was
V-J Day, the end of
World War II, and the beginning of a long road to recovery for a shattered Japan.
The
Soviet Union was responsible for
North Korea,
Sakhalin, and the
Kuril Islands, while the United States and
British Commonwealth forces were responsible for Japan,
South Korea, and Japan's remaining possessions in
Oceania. The
Republic of China was given control over
Taiwan and the
Pescadores. The
Far Eastern Commission and Allied Council For Japan were also established to supervise the occupation of Japan.
[1] On
V-J Day, United States President
Harry Truman appointed General
Douglas MacArthur as
Supreme Commander of the Allied Powers, to supervise the occupation of Japan. Japanese officials left for
Manila on
August 19 to meet MacArthur and to be briefed on his plans for the occupation. On
August 28, 150 U.S. personnel flew to
Atsugi,
Kanagawa Prefecture. They were followed by
USS ''Missouri, whose accompanying vessels landed the
4th Marine Division on the southern coast of Kanagawa. Other Allied personnel followed.
MacArthur arrived in
Tokyo on
August 30, and immediately decreed several laws: No Allied personnel were to assault Japanese people. No Allied personnel were to eat the scarce Japanese food.

On
September 2, Japan formally surrendered, signing the
Japanese Instrument of Surrender, and the occupation began. Allied (primarily American) forces supervised the country. General MacArthur was technically supposed to defer to an advisory council set up by the Allied powers but in practice did everything himself. His first priority was to set up a food distribution network; following the collapse of the ruling government and the wholesale destruction of most major cities virtually everyone was starving.

Once the food network was in place, at a cost of up to US$1 million per day, MacArthur set out to win the support of
Hirohito. The two men met for the first time on
September 28; the photograph of the two together is one of the most famous in Japanese history. However, many were shocked that MacArthur wore his standard duty uniform with no tie instead of his dress uniform when meeting the emperor. MacArthur may have done this on purpose, to send a message as to what he considered the emperor's status to be.
[1] With the sanction of Japan's reigning monarch, MacArthur had the ammunition he needed to begin the real work of the occupation. While other Allied political and military leaders pushed for
Hirohito to be tried as a
war criminal, MacArthur resisted such calls and rejected the claims of members of the imperial family such as
Prince Mikasa and
Prince Higashikuni and intellectuals like
Tatsuji Miyoshi who asked for the emperor's abdication
[2], arguing that any such prosecution would be overwhelmingly unpopular with the Japanese people.
By the end of 1945, more than 350,000 U.S. personnel were stationed throughout Japan. By the beginning of 1946, replacement troops began to arrive in the country in large numbers and were assigned to MacArthur's Eighth Army, headquartered in Tokyo's
Dai-Ichi building. Of the main Japanese islands,
Kyūshū was occupied by the 24th Infantry Division, with some responsibility for
Shikoku.
Honshū was occupied by the First Cavalry Division.
HokkaidÅ was occupied by the 11th Airborne Division.
By June 1950, all of these army units had suffered extensive troop reductions, and their combat effectiveness was seriously weakened. When
North Korea invaded
South Korea, elements of the 24th Division were flown into South Korea to try to stem the massive invasion force there, but the green occupation troops, while acquitting themselves well when suddenly thrown into combat almost overnight, suffered heavy casualties and were forced into retreat until other Japan occupation troops could be sent to assist.
The official
British Commonwealth Occupation Force (BCOF), composed of
Australian,
British,
Indian and
New Zealand personnel, was deployed on
February 21,
1946. While U.S. forces were responsible for overall military government, BCOF was responsible for supervising demilitarization and the disposal of Japan's war industries.
[2] BCOF was also responsible for occupation of several western prefectures and had its headquarters at
Kure. At its peak, the force numbered about 40,000 personnel. During 1947, BCOF began to decrease its activities in Japan, and it was officially wound up in 1951.
Accomplishments of the Occupation
Disarmament
Japan's postwar constitution, adopted under Allied supervision, included a "Peace Clause" (
Article 9), which renounced war and banned Japan from maintaining any armed forces. This was intended to prevent the country from ever becoming an aggressive military power again. However, within a decade, America was pressuring Japan to rebuild its army as a bulwark against
Communism in Asia after the
Chinese Revolution and the
Korean War, and Japan established
Self-Defense Forces. Traditionally, Japan's military spending has been restricted to about 1% of its
GNP, though this is by popular practice, not law, and has
fluctuated up and down from this figure. Recently, past
Prime Minister Junichiro Koizumi, present Prime Minister
Shinzo Abe, and other politicians have tried to repeal or amend the clause.
Liberalization
The Allies attempted to dismantle the Japanese
Zaibatsu. However, the Japanese resisted these attempts, claiming that the zaibatsu were required in order for Japan to compete internationally, and looser industrial groupings known as
keiretsu evolved. A major
land reform was also conducted, and five million acres (20,000 km²) of land were taken out of the hands of landlords and given to the farmers who worked them.
Democratization
In 1946, the Diet ratified a new
Constitution of Japan which followed closely a 'model copy' prepared by the Occupational authorities, and was promulgated as an amendment to the old
Prussian-style
Meiji Constitution. The new constitution guaranteed basic freedoms and civil liberties, abolished nobility, and, perhaps most importantly, made the emperor the symbol of Japan, removing him from politics.
Shinto was abolished as a state religion, and
Christianity reappeared in the open for the first time in decades. Women gained the right to vote, and in April 1946, 14 million turned out for the election that gave Japan its first modern prime minister,
Shigeru Yoshida.
Education reform
Before and during the war, Japanese education was based on the German system, with "Gymnasium" (English: High Schools) and universities to train students after primary school. During the occupation, Japan's secondary education system was changed to incorporate three-year junior high schools and senior high schools similar to those in the U.S.: junior high became compulsory but senior high remained optional. The
Imperial Rescript on Education was repealed, and the Imperial University system reorganized. The longstanding issue of restricting Kanji usage, which had been planned for decades but continuously opposed by more conservative elements, was also resolved during this time. The Japanese written system was drastically reorganized to give the
Toyo Kanji, predecessor of today's
JÅyÅ kanji, and orthography was greatly altered to reflect spoken usage.

Purging of war criminals
While these other reforms were taking place, various military tribunals, most notably the
International Military Tribunal for the Far East in
Ichigaya, were trying Japan's
war criminals and sentencing many to death and imprisonment. However, many suspects such as
Tsuji Masanobu,
Nobusuke Kishi,
Yoshio Kodama and
Ryoichi Sasakawa were never judged, while the
Showa Emperor, all members of the imperial family implicated in the war such as
Prince Chichibu,
Prince Asaka, Prince
Hiroyasu Fushimi,
Prince Higashikuni and
Prince Takeda, and all members of
Unit 731 were exonerated from criminal prosecutions by MacArthur.
Before the war crimes trials actually convened, the
SCAP, the
IPS and ShÅwa officials worked behind the scenes not only to prevent the imperial family from being indicted, but also to slant the testimony of the defendants to ensure that no one implicated the Emperor. High officials in court circles and the ShÅwa government collaborated with Allied GHQ in compiling lists of prospective war criminals, while the individuals arrested as ''Class A'' suspects and incarcerated in
Sugamo prison solemnly vowed to protect their sovereign against any possible taint of war responsibility.
[3] Thus, "months before the
Tokyo tribunal commenced, MacArthur's highest subordinates were working to attribute ultimate responsibility for
Pearl Harbor to
Hideki TÅjÅ"
[4] by allowing "the major criminal suspects to coordinate their stories so that the Emperor would be spared from indictment."

Politics
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
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.
End of the occupation
In 1949, MacArthur rubber-stamped a sweeping change in the SCAP power structure that greatly increased the power of Japan's native rulers, and as his attention (and that of the
White House) gradually diverted to the
Korean War, the occupation began to draw to a close. The
San Francisco Peace Treaty, signed on
September 8,
1951, marked the end of the Allied occupation, and when it went into effect on
April 28,
1952, Japan was once again an independent state (with the exceptions of
Okinawa, which remained under U.S. control until 1972, and
Iwo Jima, which remained under US control until 1968). Even though some 47,000 U.S. military personnel remain in Japan today, they are there at the invitation of the Japanese government under the terms of the
Treaty of Mutual Cooperation and Security between the United States and Japan and not as an occupying force.
Cultural reaction
★ The phrase "
shikata ga nai," or "nothing can be done about it," was commonly used in both Japanese and American press to encapsulate the Japanese public's resignation to the harsh conditions endured while under occupation.
★ The occupation was satirised in the 1956 American film ''
The Teahouse of the August Moon''.
Legacy
According to
John W. Dower, «In retrospect, apart from the military officer corps, the purge of alleged militarists and ultranationalists that was conducted under the Occupation had relatively small impact on the long-term composition of men of influence in the public and private sectors. The purge initially brought new blood into the political parties, but this was offset by the return of huge numbers of formaly purged conservative politicians to national as well as local politics in the early 1950s. In the bureaucracy, the purge was negligible from the outset... In the economic sector, the purge similarly was only mildly disruptive, affecting less than sixteen hundred individuals spread among some four hundred companies. Everywhere one looks, the corridors of power in postwar Japan are crowded with men whose talents had already been recognized during the war years, and who found the same talents highly prized in the "new" Japan.» (J. W. Dower, ''Japan in War & Peace'', New press, 1993, p.11)
The U.S. occupation left a lasting impact. The importance of democracy became better understood in Japan, and they had less respect for the proponents of a hierarchical society. Japanese democracy, freedom of the press, rejection of militarism and nationalism are all legacies of MacArthur's post-war policies. The nation has been secured within the U.S. sphere of influence and protection with the U.S. backed conservative
Liberal Democratic Party ruling in perpetuity until today. The stability in Japan has contributed to the economic success of Japan.
