Following Japan's surrender in 1945, U.S. General Douglas MacArthur, the Supreme Commander for the Allied Powers, instructed Prime Minister Kijūrō Shidehara to draft a new constitution. One of the provisions of Japan's new constitution, also known as the MacArthur Constitution or Peace Constitution, was the abolition of war as a sovereign right of the nation. This was a critical principle for MacArthur, who drew on the idea of a world without war expressed in the 1928 Kellogg-Briand Pact. The no-war provision in Article 9 of the constitution stipulated that Japan would not have the right to build or maintain a military force and would renounce war as a means to settle disputes or preserve security.

The Emperor's symbolic role
Japan's new constitution, also known as the MacArthur Constitution, was drafted in 1946 and adopted in 1947, during the Allied occupation of Japan following World War II. General Douglas MacArthur, the Supreme Commander of Allied Powers, played a significant role in its creation. One of the key provisions of this constitution was the symbolic role of the Emperor.
Prior to Japan's defeat in World War II, Emperor Hirohito was considered the country's absolute ruler and a quasi-divine figure. The new constitution stripped him of political power, reducing his role to that of a symbol of the state and the unity of the people. This symbolic role was one of the distinctive features of the constitution, along with the guarantees of civil and human rights and the renunciation of war.
Article 97 of the constitution provides for the inviolability of fundamental human rights, while Article 98 establishes the precedence of the constitution over any conflicting laws or acts of government. Article 99 binds the Emperor and public officials to observe the constitution. These articles contribute to the framework that defines the Emperor's symbolic position within the nation.
The preservation of the Emperor's role, albeit in a symbolic capacity, was a point of contention. Some conservative members of the government were reluctant to endorse this change. However, Emperor Hirohito himself supported the new constitution, likely due to his fear of being indicted as a war criminal and the potential abolition of the imperial house.
The symbolic role of the Emperor in Japan's new constitution represents a significant shift from the pre-war era, reflecting the country's transition to a more democratic and peaceful path. This provision has remained a defining aspect of Japan's governmental structure, with the constitution retaining its original form since its implementation.

Civil and human rights
Japan's new constitution, also known as the MacArthur Constitution, was drafted in 1946 and adopted in 1947, during the Allied occupation of Japan following World War II. It was largely the work of Supreme Commander for the Allied Powers, General Douglas MacArthur, and his staff. The constitution includes several provisions related to civil and human rights, which are outlined below:
Civil Liberties and Human Rights
The MacArthur Constitution protected civil liberties and human rights, including protection against self-incrimination. Article 38 states that no one may be compelled to testify against themselves, and confessions obtained under duress are not admissible. It also stipulates that no one may be convicted solely based on their confession. The constitution establishes that constitutional human rights apply not only to citizens but also to foreign nationals, except for certain rights such as the right to enter Japan or the right to vote, which are exclusive to citizens.
Inviolability of Fundamental Human Rights
Article 97 of the constitution provides for the inviolability of fundamental human rights, ensuring that these rights are protected and respected. This article reinforces the importance the constitution places on civil and human rights.
Renunciation of War
The MacArthur Constitution included a critical provision, known as Article Nine, which renounced Japan's right to wage war. This provision abolished war as a sovereign right of the nation and prohibited the use of military force for any reason, including defence. Japan was also prohibited from maintaining armed forces, further solidifying its commitment to peace and non-violence.
Universal Suffrage and Gender Equity
The new constitution granted universal suffrage and, for the first time, allowed Japanese women to vote and participate fully in the democratic process. This provision promoted gender equity and ensured that all citizens, regardless of gender, had an equal say in electing their representatives.
A Symbolic Emperor
The constitution reduced the role of the Emperor to a symbolic one, stripping Emperor Hirohito of his power and authority. This change reflected the suggestions made by the Japanese people, who proposed either the abolition of the emperor or a reduction in their authority to symbolic duties.
In summary, the provisions of Japan's new constitution related to civil and human rights included the protection of civil liberties, the inviolability of fundamental human rights, the renunciation of war, the establishment of universal suffrage, and the symbolic role of the Emperor. These provisions were designed to promote democracy, peace, and the protection of fundamental rights in postwar Japan.

Renunciation of war
The new constitution of Japan, also known as the "MacArthur Constitution", was drafted in 1946 and adopted in 1947, during the Allied occupation of the country following World War II. General Douglas MacArthur, the Supreme Commander of Allied Powers, played a key role in its creation.
One of the most important provisions of the new constitution was the renunciation of war. This provision, known as Article 9, stated that Japan would abolish war as a sovereign right of the nation. War would no longer be used as a means to settle disputes or preserve security. Japan also relinquished its right to a military force, including an army, navy, or air force, and gave up its right to belligerency. This meant that Japan would not have the right to use military force for any reason, even in defence of the nation.
The inclusion of this provision in the constitution was influenced by MacArthur, who identified the abolition of war as a critical principle in any revision of Japan's constitution. He drew on the idea of a world without war expressed in the 1928 Kellogg-Briand Pact. However, the final wording of the no-war provision was a negotiated principle, going beyond the initial American mandate.
The renunciation of war had a significant impact on Japan's foreign policy and security posture. It marked a departure from the country's previous expansionist policies and signalled a commitment to peaceful means of resolving conflicts. The provision also had implications for Japan's military capabilities and defence strategy, leading to a demilitarisation of the country.
The no-war provision in Japan's constitution has been the subject of debate and controversy. Some scholars argue that it reflects the supportive role played by the common Japanese people in the constitutional revision process, while others question its workability and appropriateness as a governmental blueprint for the country. Despite these debates, the constitution has not been amended since its inception.

Popular sovereignty
The concept of popular sovereignty in Japan's constitution is proclaimed in the name of the "Japanese people" and asserts that "sovereign power resides with the people". This means that the government is considered a sacred trust of the people, and its authority is derived from them. This principle is stated in the preamble of the constitution, which begins with an imperial edict made by the Emperor and includes his privy seal and signature, as well as the signatures of the Prime Minister and other Ministers of State.
The inclusion of popular sovereignty in Japan's new constitution was a significant shift from the previous political structure, in which Emperor Hirohito was officially regarded as Japan's absolute ruler and a quasi-divine figure. While the new constitution preserved the Emperor as a symbolic figure, it stripped him of all political power and established a parliamentary system of government.
The new constitution also provided for a bill of rights, guaranteeing fundamental human rights and civil liberties for the Japanese people. It established a bicameral National Diet as the legislative branch, with both houses being elected, as well as a Cabinet led by a Prime Minister as the executive branch, and a Supreme Court as the judicial branch.
The adoption of the new constitution, with its emphasis on popular sovereignty and democratic principles, marked a significant transformation in Japan's political system and laid the foundation for a more representative and accountable government.

Universal suffrage
The new Japanese constitution, also known as the "MacArthur Constitution", "Post-war Constitution", or "Peace Constitution", came into effect on May 3, 1947. It was drafted by U.S. General Douglas MacArthur, the Supreme Commander for the Allied Powers, and his staff, with input and modifications from a committee of Japanese scholars. This new constitution introduced universal suffrage, granting all Japanese citizens the right to vote, regardless of gender.
Prior to the new constitution, Japan had a limited suffrage system. In 1890, the first session of the Imperial Diet issued the Law on Assembly and Political Association, which banned women from joining political parties. In 1924, the year before this law was enacted, the Japanese government passed the Universal Manhood Suffrage Law, which granted voting rights to all men aged 25 and older. However, this law excluded women from the political process, despite the efforts of feminists and women's rights advocates.
Women's suffrage in Japan was a long and arduous battle. Activists like Shidzue Kato, Fusae Ichikawa, and Shigeri Yamataka played pivotal roles in the fight for women's political rights. Kato, a member of the Japanese Socialist Party, became the first woman elected to the Imperial Diet. Ichikawa focused her efforts on gaining women the right to participate in the voting process and political parties, helping to establish the New Woman Association and the League for Women's Suffrage. Yamataka worked closely with Ichikawa in the Women's Suffrage League and was elected twice to the House of Councillors, the upper house of the Diet of Japan.
The new constitution's provision for universal suffrage was a significant step forward, ensuring that all Japanese citizens, regardless of gender, had an equal say in the political process. This move towards democracy was welcomed by the Japanese people and marked a shift towards greater political equality and representation in the country.
It is worth noting that while the new constitution granted universal suffrage, it did not address all gender inequalities. The ban on women's involvement in political parties remained in place, and it would take continued efforts and structural changes to achieve full gender equality in Japan's political landscape.
