Kenpō Chōsa Suishin Giin Renmei | Diet Members Caucus for Promoting Constitutional Revision

Archived Site (IA) | Original URL (closed) 
This is the website of an official congressional association composed of more than 300 Diet members favoring constitutional revision. It provides the association's mission statement and membership, and a comparative history of the constitutions of Japan and Germany. The website claims that Germany's constitution was created by its own citizens, while the constitution of Japan was imposed by the United States. The dramatic improvement in the economy and welfare in the postwar decades helped Japan occupy an honorable position in the international community, but in order for Japan to make a further contribution to the world, it must be concerned about the preservation of world peace. They claim that the constitution (especially Article 9, clause 2) should be revised in order to adapt to new challenges and situations.


ABE Shinzō


Serving as the 63rd Prime Minister and LDP leader since 2012, Abe Shizō has vigorously called for constitutional revision. He held office between 2006 and 2007 as Prime Minister as well. When he took office back from the DPJ in 2012, he set constitutional revision as an issue of national pride for the Japanese people; see his 2012 political platform here. In 2017, he declared that he aims to enact “a new constitution” in 2020 in a speech marking  the 70th anniversary of the enactment of the Constitution of Japan in 1947. He also insisted that Article 9 stipulate the status of the SDF. The video of the 2017 speech is available here. Also, information about his activities and publications, including statements and policy platforms, are available on Kantei’s website and his social media accounts, Facebook, Twitter and Youtube.

This personal website belongs to Aichi Kazuo, former member of the House of Representatives. It offers an original revision draft known as the Aichi Draft. The draft emphasizes the role of the emperor, introduces Japanese culture and spirit in the Preamble, identifies the emperor as the chief of state, defines "Hinomaru (日の丸)" as the national flag and "Kimigayo (君が代)" as the anthem, promotes peaceful resolution of international conflicts, calls for revision of both clauses of Article 9; renames the SDF as a security force; and establishes articles about the environment, rights to privacy, and measures for dealing with national emergency.



Former Chair of the LDP headquarters for constitutional reform Funada Hajime identifies himself with “the moderates” of the LDP. He has criticized the party leadership for supporting constitutional revision by the Abe administration. According to him, the LDP’s 2012 draft was a campaign slogan aiming to take power back from the DPJ rather than a realistic constitutional draft. He claims the draft overly exaggerated nationalism and conservatism; he said that it was superfluous that the LDP proposed to replace “自衛隊” with “国防軍” and attempted to preserve traditional family values. He regularly publishes articles about various political issues on his website, including the constitution; click the “My Opinion” tab to reach his articles.

The website explains the general proceedings and background of the Research Commission on the Constitution.

「21世紀日本と憲法 第2回」(2003) |  [Japan and the Constitution in the 21st Century (2)]
This website states Nakayama's views toward constitutional revision, and explains the general proceedings and background of the Research Commission on the Constitution. It states that the current constitution leaves too much scope for interpretation leading to contradictions between the constitution and actions (as in the case when the Supreme Court justified an obviously unconstitutional decision of lowering the salary of all judges in Japan.) The site also explains how the Research Commission studied foreign constitutions and found that all had revised their constitutions. It argues against allowing citizens to vote for the prime minister (首相公選), using Israel & England as examples, and also claims the need for heightened awareness and interest of the public in constitutional revision. 
「21世紀日本と憲法 最終回」(2003) |  [Japan and the Constitution in the 21st Century (3)]
The website states Nakayama's views on the constitution and raises issues pertinent to constitutional revision. It proposes that the wide scope for interpretation of the constitution only deprives citizens of their rights. It also states that 1. the development of the Internet is raising a question regarding privacy rights; 2. the use of genetic technology and bioethics should be discussed in constitutional revision; 3. a law regarding national referendum should be established prior to constitutional revision; 4. if the prime minister is to be publicly elected in the new constitution, the current no-confidence vote by the Diet will need to be reconsidered; 5. there have been nine empresses in Japan's history, but choosing an appropriate spouse (for Princess Aiko) will be a difficult task.

The website states Ohno's recommendations regarding revising the constitution. It states that Japan should change article 9 in order to expand the role of the SDF, because it needs military alliances with other countries for self-defense.

The website explains Ozawa's views regarding constitutional revision, with specific recommendations for the new constitution in his article, "[A Tentative Amendment Draft of the Constituition of Japan] (「日本国憲法改試案」)" (Japanese Archived Site). He published this article in 1999. Ozawa holds that the current constitution was created under foreign occupation and does not reflect the views and history of Japan, and that a constitution created under an occupation is invalid. He also states that the Preamble should be rewritten; the emperor should be declared the head of state; Japan must revise article 9 to permit the right of self-defense by the SDF; and the UN should establish military forces. In addition, Ozawa proposes revising the notion of "public welfare (公共の福祉)", to include provisions for new human rights; abolishing the House of Councillors' elections, drastically revising Chapter 4 of the constitution regarding the Diet; establishing a court of justice for constitutional revision; and revising the procedure for constitutional revision.
