Basic Policies

Article 9 of the Japanese Constitution renounces war and the threat or use of force as a means of settling international disputes.(*1) In the present government's interpretation, however, it does not go so far as to deny the inalienable right of individual self-defense inherent in a sovereign state or the exercise of the right of self-defense by individual countries stipulated in Article 51 of the United Nations Charter.(*2) Judging that possession of a self defense force with necessary minimum capability would not be against the principles of the Constitution, the Japanese government established the Self-Defense Forces (SDF)(*3) in 1954 for its own national security. Japan's armed actions and armaments are thus limited to those that serve only defensive purposes, which mean that armaments cannot include such weapons as intercontinental ballistic missiles or long-range bombers. Japan's defense system is based on its own defense capability and the security treaty with the United States, signed in 1951. In accordance with the Japan-US Security Treaty (*4), the United States stations armed forces and maintains military facilities and areas in Japan, 75% of which are located in Okinawa.
In September 1997, the governments of Japan and the United States reached an agreement on new "Guidelines for Japan-US Defense Cooperation (*5)" through a meeting of the Japan-US Security Consultative Committee. The guidelines provide a general framework and policy direction for the roles and missions of the two countries and the modality of mutual cooperation and coordination, both under normal circumstances and contingencies. The Japanese government then prepared draft legislation to facilitate the implementation of the new guidelines and submitted related bills to the Diet in April 1998. The Diet passed legislation related to the new guidelines in May 1999. The related bills are: (1) a draft Law Relating to Measures for Preserving the Peace and Security of Japan in the Event of a Situation in the Areas Surrounding Japan; (2) a bill to amend the Self-Defense Forces Law; and (3) an Agreement amending the Agreement between the Government of Japan and the Government of the United States of America concerning Reciprocal Provision of Logistic Support, Supplies and Services between the Self-Defense Forces of Japan and the Armed Forces of the United States of America (the so-called amended ACSA).
In response to the terrorist attacks that took place in the United States on September 11, 2001, in October of that year the Diet approved three laws concerning terrorism, including the Anti-Terrorism Special Measures Law, which allows Japan's SDF to lend non-combat support to the US-led military forces operating overseas. In accordance with new law, several vessels of the Maritime Self-Defense Force (MSDF) have been dispatched to the Indian Ocean since November 2001 to provide logistical support for the US-led anti-terrorism campaign in Afghanistan.

Dispatch of Self-Defense Forces to Iraq
In December 2003, the SDF faced the most important turning point since it was founded in 1954 as the government approved a plan to send SDF personnel to Iraq. (*6) The SDF, whose task had long been strictly limited to national defense, engaged in its first overseas mission when the MSDF helped sweep mines in the Persian Gulf after the Gulf War in 1991. The SDF then took part in its first United Nations peacekeeping activity in Cambodia in 1992-1993. The conditions prescribing SDF's participation in peacekeeping missions have been limited to situations where a truce is in effect between the warring parties.
The present situation, however, appears completely different from missions of the past as Iraq is a country in which fighting is still taking place. Under the plan, some 600 Ground SDF (GSDF) troops supply medical services and water and build schools and other public facilities in southeastern parts of Iraq as humanitarian assistance, while MSDF and Air SDF (ASDF) units engage in transportation of aid materials using military ships and planes.
Due to strong resistance to the early dispatch of the GSDF, which is seen as an easier target for terrorist attacks, the government deployed ASDF personnel first. An ASDF advance team was sent to Kuwait in December 2003, followed by three C-130 transport planes arriving in Kuwait in January 2004. In February 2004, about 80 GSDF personnel tasked with building fortified barracks were dispatched for Samawah, a city in southern Iraq, to prepare for the arrival of the main unit of about 440 troops by the spring. The basic plan limits the SDF deployment period from Dec. 15, 2003, to Dec. 14, 2004. It calls for up to 200 vehicles to accompany the GSDF, which will be equipped with such heavy gear as high-powered recoilless rifles and anti-tank weapons. The MSDF will send up to two transport ships and two destroyers. The ASDF will deploy up to eight aircraft, including C-130 transport planes.

The Three Non-Nuclear Principles
As the only country in the world having been subjected to atomic attack, Japan has firmly upheld its self-imposed "three non-nuclear principles (*7)" of not possessing, manufacturing, or permitting the entry into Japan of nuclear weapons. It has been the government's policy not to possess nuclear weapons of any kind, and in line with this policy Japan is a party to the Nuclear Non-Proliferation Treaty.


The SDF at Present

As of March 2002, the SDF had a total of 258,581 uniformed personnel in its three branches—GSDF, MSDF and ASDF. (The three branches had a total of 47,900 uniformed reserve personnel.)(*1) All uniformed personnel are volunteers, as Japan has no conscription system. The breakdown was as follows:

Joint Staff Council: 1,656 uniformed personnel.
GSDF: 148,197 uniformed personnel.
MSDF: 44,404 uniformed personnel.
ASDF: 45,582 uniformed personnel.

The GSDF has 1,040 tanks and 660 armored vehicles. The MSDF has 54 destroyers in addition to 16 submarines and 99 P-3C anti-submarine aircrafts, while the ASDF has 336 fighters including F-15J/DJ, F-4EJ,and F-1.

Defense Spending
In 1976 the cabinet decided that defense spending should not exceed 1% of gross national product (GNP). This ceiling, embedded in the public conscience from the time it was set, was replaced in 1987 with a formula that adjusted annual defense spending according to the overall spending stipulated in the mid-term defense program. In December 2000, the government's Security Council and cabinet approved a new Mid-Term Defense Program (fiscal years 2001-2005) totaling \25.16 trillion, an increase of ¥930 billion over the previous program (fiscal 1996-2000), with an average annual growth rate of 0.7%.(*2) The new Mid-Term Defense Program calls for improving the capabilities of the SDF to better deal with guerrilla and nuclear, biological, or chemical attacks, strengthening the SDF's capacity to cope with natural disasters, and upgrading information technology systems and control-and-command systems in the SDF. The new program also emphasizes efforts to restructure and streamline the SDF in accordance with the government's overall defense policy. In the budget for fiscal year 2003, the government earmarked ¥4.92 trillion to defense spending, a slight decrease of 0.3% from the previous fiscal year.(*3)
The defense budget includes Japanese financial assistance for bearing part of the stationing cost of the US Forces in Japan (USFJ), which started in fiscal 1978. This host nation support has been stipulated in a special bilateral agreement and covers, among other things, payment of the salaries of Japanese workers employed at the US military bases, costs of family housing, and utilities, including electricity, gas and water supply required by the USFJ.
