- Japan's non-nuclear policy
Japanexhibits a firm non-nuclear weapons policy, most popularly articulated as the Three Non-Nuclear Principlesof nonpossession, nonproduction, and nonintroduction of nuclear weapons.
The policy only applies to
nuclear weapons, not all nuclear technology; peaceful nuclear poweris common in Japan, and accounts for 30% of Japanese electric production.
The policy took decades to appear in written form. Following
World War IIand the deconstruction of the imperial military, Japan found itself dependent upon the U.S. "nuclear umbrella" from outside aggression. This was formalized in the Security Treaty Between the United States and Japan, a corollary to the Treaty of Peace with Japan, which authorized the U.S. to deploy military forces in Japan in order "to contribute to the maintenance of the international peace and security in the Far East and to the security of Japan against armed attack from without". The treaty was first invoked in 1953: following a series of Japanese airspace violations by Soviet MiG-15s, the Japanese Foreign Ministry requested U.S. intervention.

Early public opposition
In the years after the occupation, with the
atomic bombings of Hiroshima and Nagasakistill fresh in the Japanese consciousness, public sentiment was strongly against the use, and even presence on Japanese soil, of nuclear weapons. This sentiment was evidenced by the widely-reported accidental irradiation of the "Daigo Fukuryū maru" from a U.S. hydrogen bombtest in 1954. News of the incident aroused public fears over radiation and outcry against atomic and nuclear weapons testing. ("Main article: Daigo Fukuryu Maru.")
July 28, 1955, the U.S. announced its intention to equip military bases in Japan with Honest Johns, conventional missiles which could also be fitted with atomic warheads. The Eisenhower Administrationand Hatoyama Cabinet had been arranging for the deployment since March, but the announcement sparked outrage in the Diet and public protest. Okazaki and Hatoyama were forced to make assurances to the Diet that the missiles would not be equipped with nuclear warheads on Japanese territory, and that the United States would have to consult with the entire government before introducing nuclear weapons into Japan.
The language of the
Atomic Energy Basic Law, adopted in December 1955, reflects the public sentiment, restricting "the research, development and utilization of atomic energy" to "peaceful purposes". Soon after, in 1957, Prime Minister Nobusuke Kishistated his opinion that nuclear weapons were not technically prohibited by Article 9 of the Peace Constitution, though for reasons of humanity and in accordance with popular sentiment national policy should prohibit both their use and introduction. (Even this interpretation of the Constitution, however, drew criticism.) Prime Minister Ikeda Hayatoreaffirmed the policy in 1962. [Weinstein, Martin E.

Satō's "Four Pillars" Policy
Liberal Democratic Party (LDP) President Eisaku Satō was elected Prime Minister in December of 1964 (only a month after
Chinarevealed its nuclear weapons capability with a test explosion). Although privately supportive of Japanese nuclearization, circumstances led Prime Minister Satō to first articulate the now-standard Three Non-Nuclear Principles, and he is remembered for his contributions to nonproliferation. Most significantly, he was determined to reacquire the island of Okinawafrom U.S. occupation. Frustrated by strong public sentiment against the U.S. nuclear presence there, Satō struck a deal with the Johnson Administration, exchanging control of Okinawa for Japan's entry into the Nuclear Non-Proliferation Treaty(NPT).
To ease public misgivings about his administrations nuclear ambitions, Satō introduced the Three Non-Nuclear Principles to the Diet in 1967. Retroactively, to lessen the principles' restriction on Japanese military defense options, in 1968 Satō broadened the principles into the "Four Pillars Nuclear Policy" of (1) promoting the use of
nuclear powerfor peaceful purposes, (2) global nuclear disarmament, (3) reliance on the U.S. nuclear deterrentfor protection from nuclear attack, and (4) the Three Principles. In particular, the fourth pillar called for adherence to the principles "under the circumstances where Japan's national security is guaranteed by the other three policies", implying that a chance of circumstances might allow Japan to develop a nuclear program. Amid anxiety over U.S. involvement in the Vietnam War, aggression between North and South Korea, and tense Cross-Strait relations, this stipulation served to reassure the Diet that the nuclear option would still be considered if any of the conflicts escalated to threaten Japanese national security.
This policy of nuclear abstention was justified internally by the "
1968/1970 Report", the product of a secret study commissioned by the Satō Government (leaked to the public in 1994). The document was a comprehensive cost-benefit analysisof the nuclear option from technical, economic, political, and international perspectives. Ultimately favoring non-nuclearization, the document concluded that the U.S. nuclear deterrent sufficed to deter outside aggression. It also stressed both Japan's extreme vulnerability to nuclear attack (high population density) and the likelihood of international isolation in the wake of a nuclear weapons program. [Campbell, Kurt M. and Sunohara, Tsuyoshi (2004). "Japan: Thinking the Unthinkable". "The Nuclear Tipping Point: Why States Reconsider Their Nuclear Choices" Ch. 9: 218–253. ISBN 0-8157-1331-2] Though Satō thought little of the principles and was pliant in his enforcement of the principle of nonintroduction, [ [http://www.japantimes.co.jp/cgi-bin/getarticle.pl5?nn20000611a1.htm "Peace Prize winner Sato called nonnuclear policy 'nonsense'"] . "The Japan Times", 11 June 2000.] in view of popular opinion and the embracing of the policy by the rival Social Democratic Party, he and the LDP also remained vocally supportive.
In 1970, as desired by the U.S. but after much hesitation and with some key stipulations, Japan signed the NPT; and in 1972, relieved of U.S. nuclear weapons, Okinawa reverted to Japanese rule. The Diet passed a resolution formally adopting the principles in 1971, though they were not made law. Eisaku Satō was presented with the
Nobel Peace Prizein 1974, in large part for his work toward Japan's entry into the NPT. In his Nobel Lecture (on the seventh anniversary of his original statement to the Diet), Satō reiterated and discussed the Three Non-Nuclear Principles and expressed hope and confidence that future governments would adopt them as well. [ [http://nobelprize.org/peace/laureates/1974/sato-lecture.html Eisaku Satō's Nobel Lecture] , 11 December 1974.]
Opinion polls have consistently revealed that public opinion is overwhelmingly opposed to nuclearization [Kamiya, Matake (2002). [http://www.twq.com/03winter/docs/03winter_kamiya.pdf "Nuclear Japan: Oxymoron or Coming Soon?"] . "The Washington Quarterly" 26 1: 63–75.] , as several events over the decades following World War II, even after the end of the Cold War, have demonstrated.
The Kobe Formula
The port of
Kobewas used heavily by the U.S. fleet during its postwar occupation, which ended in 1974. Throughout the occupation, U.S. military facilities at Kobe Port were the target of continuous public protest. Public petitions after Kobe's return to Japan culminated in a March 18, 1975resolution by the City Councilto prohibit nuclear-armed vessels from entering the port. [ [http://www.prop1.org/prop1/jkobef.htm "Resolution on the Rejection of the Visit of Nuclear-Armed Warships into Kobe Port"] . Kobe City Council, 18 March 1975.] U.S. policy being to neither confirm nor deny nuclear weapons deployment, this resolution effectively removed the U.S. naval presence from Kobe Port. Amid the presence of nuclear-powered U.S. vessels and concerns that the government allowed nuclear-armed warships into Japanese ports (later confirmed), this resolution became the first major application of the three non-nuclear principles. The strict policy has become known as the "Kobe Formula", and since its inception several thousand Japanese municipalities have adopted similar nuclear-free resolutions. [Kajimoto, Shushi (2001).

"2001 World Conference against A & H Bombs", 3–5 August 2001.]
In recent years Japanese policymakers have been increasingly public in calling the three non-nuclear principles into question. In October of 1999,
Deputy Vice Minister of Defense Shingo Nishimuraproposed to the Diet (as stated in a previous interview) that, in light of the North Korean threat, serious debate on Japan's nuclearization should begin. Public furor immediately forced Nishimura to resign from the (Keizo) Obuchi Cabinet. [French, Howard W. (1999). [http://www.fas.org/news/japan/991021001063_TopNews.htm "Furor in Japan as Military Official Advocates Nuclear Weapons"] . "The New York Times", 21 October 1999.]
In May of 2002
Deputy Chief Cabinet Secretary Shinzo Aberepeated the observation of Kishi that Article 9 did not preclude Japan from owning sufficiently small (strictly defensive) nuclear weapons, including ICBMs and atomic bombs. In June of that year, Chief Cabinet Secretary Yasuo Fukuda, in an off-the-record talk with reporters (for which he later took responsibility), remarked further that "circumstances and public opinion could require Japan to possess nuclear weapons". Despite being highly hypothetical, both comments provoked public outcry and a sit-in protest in Hiroshima followed Fukuda's remark. Shortly thereafter Fukuda amended his statement, specifying that Japan could not own ICBMs under Article 9. [ [http://www.chugoku-np.co.jp/abom/02e/An02060202.html "Non-nuclear principles to be reviewed"] . "Chūgoku Shimbun Peace News", 2 June 2002.]
Fukuda was not forced to resign; Prime Minister
Junichiro Koizumidescribed his remarks as "simply an observation that any basic policy of a country can be reviewed" and insists that his government has no intention of review the principles. [Berkofsky, Axel (2002). [http://www.atimes.com/japan-econ/DF13Dh01.html "Koizumi under a nuclear smokescreen"] . "Asia Times", 13 June 2002.] Koizumi continues to reaffirm the principles in each of his addresses for the Hiroshima and Nagasaki Peace Memorial Ceremonies.

More fervent criticism of Japan's non-nuclear policy has come from a few well-known academics and writers, including
Kyoto Universityprofessor Terumasa Nakanishiand literary critic Kazuya Fukuda(who penned the article "A nuclear declaration for Japan" for "Voice" magazine). The majority of writers and scholars, however, tend to support non-nuclearism.
