Japan Self-Defense Forces

  (Redirected from Japan Self Defense Forces)

The Japan Self-Defense Forces (自衛隊, Jieitai), JSDF, also referred to as the Self-Defense Forces (SDF), Japan Defense Forces (JDF), or the Japanese Armed Forces,[6] are the unified military forces of Japan that were established in 1954, and are controlled by the Ministry of Defense. The JSDF ranked as the world's fourth most-powerful military in 2015[7] and it has the world's eighth-largest military budget.[8] In recent years they have been engaged in international peacekeeping operations including UN peacekeeping.[9]

Recent tensions, particularly with North Korea,[10] have reignited the debate over the status of the JSDF and its relation to Japanese society.[11] New military guidelines, announced in December 2010, will direct the JSDF away from its Cold War focus on the former Soviet Union to a focus on China, especially regarding the territorial dispute over the Senkaku Islands, while increasing cooperation with the United States, South Korea, Australia and India.[12]



Early developments (1945–2000)Edit

Deprived of any military capability after being defeated by the Allies in World War II and signing a surrender agreement presented by General Douglas MacArthur in 1945, Japan had only the U.S. occupation forces and a minor domestic police force on which to rely for security. Rising Cold War tensions in Europe and Asia, coupled with leftist-inspired strikes and demonstrations in Japan, prompted some conservative leaders to question the unilateral renunciation of all military capabilities. These sentiments were intensified in 1950 as occupation troops began to be moved to the Korean War (1950–53) theater. This left Japan virtually defenseless, vulnerable, and very much aware of the need to enter into a mutual defense relationship with the United States to guarantee the nation's external security. Encouraged by the American occupation authorities, the Japanese government in July 1950 authorized the establishment of a National Police Reserve (警察予備隊, Keisatsu-yobitai), consisting of 75,000 men equipped with light infantry weapons.[13]

Under the terms of the Treaty of Mutual Cooperation and Security between the United States and Japan, United States forces stationed in Japan were to deal with external aggression against Japan while Japanese ground and maritime forces would deal with internal threats and natural disasters. Accordingly, in mid-1952, the National Police Reserve was expanded to 110,000 men and named the National Safety Forces.[14] The Coastal Safety Force, which had been organized in 1950 as a waterborne counterpart to the National Police Reserve, was transferred with it to the National Safety Agency to constitute an embryonic navy.

(1) Aspiring sincerely to an international peace based on justice and order, the Japanese people forever renounce war as a sovereign right of the nation and the threat or use of force as means of settling international disputes.
(2) In order to accomplish the aim of the preceding paragraph, land, sea, and air forces, as well as other war potential, will never be maintained. The right of belligerency of the state will not be recognized.

The trauma of World War II produced strong pacifist sentiments among the nation. In addition, under Article 9 of the United States–written 1947 constitution, Japan forever renounces war as an instrument for settling international disputes and declares that Japan will never again maintain "land, sea, or air forces or other war potential."[1] Later cabinets interpreted these provisions as not denying the nation the inherent right to self-defense and, with the encouragement of the United States, developed the JSDF step by step.

On July 1, 1954, the National Security Board was reorganized as the Defense Agency, and the National Security Force was reorganized afterwards as the Japan Ground Self-Defense Force (de facto post-war Japanese Army), the Japan Maritime Self-Defense Force (de facto post-war Japanese Navy) and the Japan Air Self-Defense Force (de facto post-war Japanese Air Force), with General Keizō Hayashi appointed as the first Chairman of Joint Staff Council—professional head of the three branches. The enabling legislation for this was the 1954 Self-Defense Forces Act (Act No. 165 of 1954).[1]

The Far East Air Force, U.S. Air Force, announced on 6 January 1955, that 85 aircraft would be turned over to the fledgling Japanese air force on about 15 January, the first equipment of the new force.[15]

In 1983, Japanese Prime Minister Yasuhiro Nakasone pledged to make Japan an "unsinkable aircraft carrier in the Pacific", assisting the United States in defending against the threat of Soviet bombers.[16][17]

Although possession of nuclear weapons is not explicitly forbidden in the constitution, Japan, as the only nation to have experienced the devastation of nuclear attacks, expressed early its abhorrence of nuclear arms and its determination never to acquire them. The Atomic Energy Basic Law of 1956 limits research, development, and use of nuclear power to peaceful uses only. Beginning in 1956, national policy embodied "three non-nuclear principles"—forbidding the nation to possess or manufacture nuclear weapons or to allow them to be introduced into its territories. In 1976 Japan ratified the Treaty on the Non-Proliferation of Nuclear Weapons (adopted by the United Nations Security Council in 1968) and reiterated its intention never to "develop, use, or allow the transportation of nuclear weapons through its territory". Nonetheless, because of its generally high technology level and large number of operating nuclear power plants, Japan is generally considered to be "nuclear capable", i.e., it could develop a usable weapon in a short period if the political situation changed significantly.[18]

Recent developments (2000-present)Edit

On June 8, 2006, the Cabinet of Japan endorsed a bill elevating the Defense Agency (防衛庁) under the Cabinet Office to full-fledged cabinet-level Ministry of Defense (防衛省). This was passed by the National Diet in December 2006, and has been enforced since January 9, 2007.[19]

On 18, September 2015, the National Diet enacted the 2015 Japanese military legislation, a series of laws that allow Japan's Self-Defense Forces to collective self-defense of allies in combat for the first time under its constitution. The Self-Defense Forces may provide material support to allies engaged in combat internationally. It also allows SDF troops to defend weapons platforms of foreign countries that contribute to Japan’s defense. The justification is that by not defending/supporting an ally, it would weaken alliances and endanger Japan. These were Japan's broadest changes to its defense laws since World War II.[20]

A Credit Suisse survey published in 2015 ranked Japan as the world’s fourth most-powerful military behind the United States, Russia and China.[7]

In May 2017, Japanese Prime Minister Shinzo Abe set a 2020 deadline for revising the Article 9 of the Japanese Constitution, a clause in the national Constitution of Japan outlawing war as a means to settle international disputes involving the state.[21][22][23][23][24]

Japan activated the Amphibious Rapid Deployment Brigade, its first marine unit since World War Two, on April 7, 2018. They're trained to counter invaders from occupying Japanese islands.[25]

The Ministry of Defense said from 1 October 2018, the maximum age for enlisted personnel and non-commissioned officer applicants will be raised to 32 from 26 to secure “a stable supply of Self-Defense Forces (military) personnel amid a declining pool of recruits due to the recently declining birth rate.”[26]

In March 2019, the Ministry of Defense will establish its first regional cyber protection unit in the Western Army of the Japan Ground Self-Defense Force (JGSDF) to safeguard defense communications from cyber attacks. Such as for personnel deployed on remote islands with no established secure lines.[27]


Standard of the Prime Minister

The Prime Minister is the commander-in-chief of the Japan Self-Defense Forces. Military authority runs from the Prime Minister to the cabinet-level Minister of Defense of the Japanese Ministry of Defense.A[28][29][30][31]

The Prime Minister and Minister of Defense are advised by the Chief of Staff, Joint Staff (統合幕僚長, Tōgō Bakuryō-chō) (currently Katsutoshi Kawano), who heads the Joint Staff (統合幕僚監部, Tōgō Bakuryō Kanbu). The Joint Staff includes a Senior Enlisted Advisor to the Chief of Staff, Joint Staff, the Vice Chief of Staff, Joint Staff (currently Kōichi Isobe), an Administrative Vice Chief of Staff, as well as numerous departments and special staffs.[32] Each service branch is headed by their respective Chiefs of Staff; the Chief of Staff of the Japan Ground Self-Defense Force (JGSDF) (currently Kōji Yamazaki), the Japan Maritime Self-Defense Force (JMSDF) (currently Yutaka Murakawa), and the Japan Air Self-Defense Force (JASDF) (currently Yoshinari Marumo).[33][34][35][36]

The Chief of Staff, Joint Staff, a four star Admiral or General, is the highest-ranking military officer in the Japan Self-Defense Forces, and is the head of the Operational Authority over the Japan Self-Defense Forces, executing orders of the Minister of Defense with directions from the Prime Minister.[31][37] The Chief of Staff, Joint Staff supervises the service branches operations, and would assume command in the event of a war, but his or her powers are limited to policy formation and defense coordination during peacetime.[28][29]

The chain of Operational Authority runs from the Chief of Staff, Joint Staff to the Commanders of the several Operational Commands. Each service branches Chiefs of Staff (JGSDF, JMSDF, JASDF) have administrative control over their own services.[30][37][38]

Service branchesEdit

Service unitsEdit

  • Five armies
  • Five maritime districts
  • Four air defense forces

Defense policyEdit

National Security CouncilEdit

On December 4, 2013, the National Security Council was established, with the aim of establishing a forum which will undertake strategic discussions under the Prime Minister on a regular basis and as necessary on various national security issues and exercising a strong political leadership.

National Security StrategyEdit

On December 17, 2013, National Security Strategy was adopted by Cabinet decision. NSS sets the basic orientation of diplomatic and defense policies related to national security. NSS presents the content of the policy of "Proactive Contribution to Peace" in a concrete manner and promotes better understanding of Japan's national security policy.[39]

On July 25, 2018, the Japanese government settled on a 3-year strategy to counter possible cyberattacks against key parts of the nation's infrastructure ahead of the 2020 Tokyo Olympic and Paralympic Games.[40]


In 1976, then Prime Minister Miki Takeo announced defense spending should be maintained within 1% of Japan's gross domestic product (GDP),[41] a ceiling that was observed until 1986.[42] As of 2005, Japan's military budget was maintained at about 3% of the national budget; about half is spent on personnel costs, while the rest is for weapons programs, maintenance and operating costs.[43] As of 2011, Japan has the world's eighth-largest military budget.[8][44]

Anti-ballistic missile deploymentEdit

After the North Korean Kwangmyŏngsŏng-1 satellite launching in August 1998, which some regarded as a ballistic missile test, the Japanese government decided to participate in the American anti-ballistic missile (ABM) defense program. In August 1999, Japan, Germany and the US governments signed a Memorandum of Understanding of joint research and development on the Aegis Ballistic Missile Defense System.[45] In 2003, the Japanese government decided to deploy three types of ABM system, air defense vehicles, sea-based Aegis and land-based PAC-3 ABM.

The four Kongō class Aegis destroyers of the Japan Maritime Self-Defense Force were modified to accommodate the ABM operational capability.[46] On December 17, 2007, JS Kongō successfully shot down a mock ballistic missile by its SM-3 Block IA, off the coast of Hawaii.[47] The first PAC-3 (upgraded version of the MIM-104 Patriot) firing test by the Japan Air Self-Defense Force was carried out in New Mexico on September 17, 2008.[48] PAC-3 units are deployed in 6 bases near metropolises, including Tokyo, Osaka, Nagoya, Sapporo, Misawa and Okinawa.

Japan participates in the co-research and development of four Aegis components with the US: the nose cone, the infrared seeker, the kinetic warhead, and the second-stage rocket motor.[49][50]

On 30 July 2018, Japan picked Lockheed Martin Corp to build a $1.2 billion radar for two ground-based Aegis ballistic missile defense stations. These are meant to guard against missile strikes.[51] On the same day, Japan's Defense Ministry said to be considering to withdraw PAC3 missile interceptor units from the country's northern and western region amid an easing of tensions with North Korea. Ministry officials told that North Korea is less likely to fire ballistic missiles after it held a summit with the United States last month. But the officials also said the ministry will maintain its order to destroy any incoming missiles. They added that the ministry will be ready to quickly redeploy the PAC3 units if the situation changes.[52]

Unarmed combat systemEdit

JSDF soldiers are trained in the military self-defense art of toshu kakuto (徒手格闘), developed in 1952 by Major Chiba Sansu from a synthesis of jujutsu, karate, aikijujutsu, boxing and wrestling. The techniques of toshu kakuto are simplified and direct, to allow for their application whilst in combat dress and carrying field kit. There is an emphasis on the rapid transmission of maximum force in strikes, and for this reason toshu kakuto eschews the fully rotated punches and instep kicks of most karate forms in favour of vertical thrust punches and straight heel kicks.[53]

Missions and deploymentsEdit

The outer outline specified quotas of personnel and equipment for each force that were deemed necessary to meet its tasks. Particular elements of each force's mission were also identified. The JGSDF was to defend against ground invasion and threats to internal security, be able to deploy to any part of the nation, and protect the bases of all three services of the Self-Defense Forces. The JMSDF was to meet invasion by sea, sweep mines, patrol and survey the surrounding waters, and guard and defend coastal waters, ports, bays, and major straits. The JASDF was to render aircraft and missile interceptor capability, provide support fighter units for maritime and ground operations, supply air reconnaissance and air transport for all forces, and maintain airborne and stationary early warning units.[citation needed]

Disaster relief, JGSDF

The JSDF disaster relief role is defined in Article 83 of the Self-Defense Forces Law of 1954, requiring units to respond to calls for assistance from prefectural governors to aid in fire fighting, earthquake disasters, searches for missing persons, rescues, and reinforcement of embankments and levees in the event of flooding. The JSDF has not been used in police actions, nor is it likely to be assigned any internal security tasks in the future.[citation needed]

In late June/early July 2014, Prime Minister Shinzo Abe and his cabinet agreed to lift the long-term ban in engaging Japanese troops abroad, since the end of the Second World War, in a bid to strengthen the Japanese situation amid an ever-growing Chinese military aggression and North Korea's nuclear weapons programme. Japan had adhered to the "pacifist" article 9 of the constitution, but would revise and might reinterpret it in order for this to take effect.[54]

In June 1992, the National Diet passed a UN Peacekeeping Cooperation Law which permitted the JSDF to participate in UN medical, refugee repatriation, logistical support, infrastructural reconstruction, election-monitoring, and policing operations under strictly limited conditions.[citation needed][55]

The non-combatant participation of the JSDF in the United Nations Transitional Authority in Cambodia (UNTAC) in conjunction with Japanese diplomatic efforts contributed to the successful implementation of the 1991 Paris Peace Accords for Cambodia.

Chief Cabinet Secretary Nobutaka Machimura had stated that discussions with Defense Minister Shigeru Ishiba and Foreign Minister Masahiko Komura were taking place regarding the possibility of creating a permanent law for JSDF forces to be deployed in peacekeeping missions outside Japan.[56] The adoption of a permanent peacekeeping law has been considered by the government, according to the Mainichi Daily News.[57] In 2014, the LDP did not make progress due to concerns from Komeito that JSDF forces can be sent to a peacekeeping operation where Japan is not involved.[58]

Land deploymentsEdit

Deployment Start date End date JSDF numbers Comments
Mozambique May 1993 ? 35 United Nations Operation in Mozambique[citation needed]
East Timor February 2002 June 2004 680 engineering unit as part of United Nations Transitional Administration in East Timor

South Sudan 12 December 2016 17 April 2017 350 ceasefire observers and security[61]

In 2004, the Japanese government ordered a deployment of troops to Iraq at the behest of the United States: A contingent of the Japan Self-Defense Forces was sent in order to assist the U.S.-led Reconstruction of Iraq. This controversial deployment marked a significant turning point in Japan's history, as it is the first time since the end of World War II that Japan sent troops abroad except for a few minor UN peacekeeping deployments. Public opinion regarding this deployment was sharply divided, especially given that Japan's military is constitutionally structured as solely a self-defense force, and operating in Iraq seemed at best tenuously connected to that mission. The Koizumi administration, however, decided to send troops to respond to a request from the US. Even though they deployed with their weapons, because of constitutional restraints, the troops were protected by Japanese Special Forces troops and Australian units. The Japanese soldiers were there purely for humanitarian and reconstruction work, and were prohibited from opening fire on Iraqi insurgents unless they were fired on first. Japanese forces withdrew from Iraq in 2006.

Japan provided logistics units for the United Nations Disengagement Observer Force Zone, which supervises the buffer zone in the Golan Heights, monitors Israeli and Syrian military activities, and assists local civilians.[citation needed]

In the aftermath of an earthquake in Haiti, Japan deployed a contingent of troops, including engineers with bulldozers and heavy machinery, to assist the United Nations Stabilization Mission in Haiti. Their duties were peacekeeping, removal of rubble, and the reconstruction of roads and buildings.[62] Japanese forces are frequent among the international disaster relief teams, with deployments in Rwanda (1994), Honduras (1998), Turkey (1999), West Timor (1999-2000), Afghanistan (2001), Iraq (2003), Iran (2003-2004), Thailand (2004-2005), Indonesia (2005), Russia (2005), Pakistan (2005), Indonesia (2006), Indonesia (2009), Haiti (2010), Pakistan (2010), New Zealand (2011).[63]

Naval and air overseas deploymentsEdit

The Japan Maritime Self-Defense Force deployed a force off the coast of Somalia to protect Japanese ships from Somali Pirates. The force consists of two destroyers (manned by approximately 400 sailors), patrol helicopters, speedboats, eight officers of the Japan Coast Guard to collect criminal evidence and handle piracy suspects, a force of commandos from the elite Special Boarding Unit, and P-3 Orion patrol aircraft in the Gulf of Aden.[64] On 19 June 2009, the Japanese Parliament finally passed an anti-piracy bill, which allows their force to protect non Japanese vessels.[65] In May 2010, Japan announced it intended to build a permanent naval base in Djibouti to provide security for Japanese ships against Somali pirates.[66] Construction of the JSDF Counter-Piracy Facility in Djibouti commenced in July 2010, completed in June 2011 and opened on 1 July 2011.[67] Initially, the base was to house approximately 170 JSDF personnel and include administrative, housing, medical, kitchen/dining, and recreational facilities as well as an aircraft maintenance hangar and parking apron.[68] The base now houses approximately 200 personnel and two P-3C aircraft.[67]

Amphibious forceEdit

In light of tensions over the Senkaku Islands, Japan is in the process of creating the Amphibious Rapid Deployment Brigade. This unit will be designed to conduct amphibious operations and to recover any Japanese islands taken by an adversary.[69]

Japan activated its first marine unit since World War Two on April 7, 2018. The marines of the Japanese Ground Self-Defense Force (JGSDF)'s Amphibious Rapid Deployment Brigade, gathered at a ceremony activating the brigade at JGSDF's Camp Ainoura in Sasebo, on the southwest island of Kyushu, Japan. They're trained to counter invaders from occupying Japanese islands along the edge of the East China Sea that Tokyo fears are vulnerable to attack.[25]

Uniforms, ranks, and insigniaEdit

The arm of service to which members of the ground force are attached is indicated by branch insignia and piping of distinctive colors: for infantry, red; artillery, yellow; armor, orange; engineers, violet; ordnance, light green; medical, green; army aviation, light blue; signals, blue; quartermaster, brown; transportation, dark violet; airborne, white; and others, dark blue. The cap badge insignia the JGSDF is a sakura cherry blossom bordered with two ivy branches underneath, and a single chevron centered on the bottom between the bases of the branches; the JMSDF cap badge insignia consists of a fouled anchor underneath a cherry blossom bordered on the sides and bottom by ivy vines; and the JASDF cap badge insignia features a heraldic eagle under which is a star and crescent, which is bordered underneath with stylized wings.[70]

There are nine officer ranks in the active JSDF, along with a warrant officer rank, five NCO ranks, and three enlisted ranks. The highest NCO rank, first sergeant (senior chief petty officer in the JMSDF and senior master sergeant in the JASDF), was established in 1980 to provide more promotion opportunities and shorter terms of service as sergeant first class, chief petty officer, or master sergeant. Under the earlier system, the average NCO was promoted only twice in approximately thirty years of service and remained at the top rank for almost ten years.[70]

Recruitment and conditions of serviceEdit

The total strength of the JSDF is 247,154 in 2016.[71][72] In addition, the JSDF maintained a total of 47,900 reservists attached to the three services. Even when Japan's active and reserve components are combined, however, the country maintains a lower ratio of military personnel to its population than does any member nation of the North Atlantic Treaty Organization (NATO). Of the major Asian nations, only India, Indonesia, Malaysia and Thailand keep a lower ratio of personnel in arms, although because India and Indonesia have much larger populations, they have larger numbers of personnel.[citation needed]

JSDF uniformed personnel are recruited as private, E-1, seaman recruit, and airman basic for a fixed term. Ground forces recruits normally enlist for two years; those seeking training in technical specialties enlist for three. Naval and air recruits normally enlist for three years. Officer candidates, students in the National Defense Academy and National Defense Medical College, and candidate enlist students in technical schools are enrolled for an indefinite period. The National Defense Academy and enlisted technical schools usually require an enrollment of four years, and the National Defense Medical College require six years.[citation needed]

When the JSDF was originally formed, women were recruited exclusively for the nursing services. Opportunities were expanded somewhat when women were permitted to join the JGSDF communication service in 1967 and the JMSDF and JASDF communication services in 1974. By 1991, more than 6,000 women were in the JSDF, about 80% of service areas, except those requiring direct exposure to combat, were open to them. The National Defense Medical College graduated its first class with women in March 1991, and the National Defense Academy began admitting women in FY 1992.[73]

JSDF personnel benefits are not comparable to such benefits for active-duty military personnel in other major industrialized nations. Health care is provided at the JSDF Central Hospital, fourteen regional hospitals, and 165 clinics in military facilities and on board ship, but the health care only covers physical examinations and the treatment of illness and injury suffered in the course of duty. There are no commissary or exchange privileges. Housing is often substandard, and military appropriations for facilities maintenance often focus on appeasing civilian communities near bases rather than on improving on-base facilities.[70]

In 2010, Sapporo District Court fined the state after a female Air JSDF member was sexually assaulted by a colleague then forced to retire, while the perpetrator was suspended for 60 days.[74]

Overseas dispatchEdit

The JSDF sent six small-scale squadrons to the Persian Gulf on April 26, 1991, and approved the June 1994 UN Peacekeeping Activity (Parliamentary Peacekeeping) Cooperation bill in the House of Representatives in Japan. From September 11, Self-Defense Forces have started overseas activities such as dispatching UN peacekeepers to Cambodia.In 2003, Japan created a law to deal with armed attacks, amend the Self-Defense Forces law. In 2004, Japan dispatched for two and a half years to the Samawa district of southern Iraq under the Special Measures for Iraqi Recovery Support Act. in 2005

Role in Japanese societyEdit

Appreciation of the JSDF continued to grow in the 1980s, with over half of the respondents in a 1988 survey voicing an interest in the JSDF and over 76% indicating that they were favourably impressed. Although the majority (63.5%) of respondents were aware that the primary purpose of the JSDF was maintenance of national security, an even greater number (77%) saw disaster relief as the most useful JSDF function. The JSDF therefore continued to devote much of its time and resources to disaster relief and other civic action. Between 1984 and 1988, at the request of prefectural governors, the JSDF assisted in approximately 3,100 disaster relief operations, involving about 138,000 personnel, 16,000 vehicles, 5,300 aircraft, and 120 ships and small craft. In addition, the JSDF participated in earthquake disaster prevention operations and disposed of a large quantity of World War II explosive ordnance, especially in Okinawa Prefecture. The forces also participated in public works projects, cooperated in managing athletic events, took part in annual Antarctic expeditions, and conducted aerial surveys to report on ice conditions for fishermen and on geographic formations for construction projects. Especially sensitive to maintaining harmonious relations with communities close to defense bases, the JSDF built new roads, irrigation networks, and schools in those areas. Soundproofing was installed in homes and public buildings near airfields.

Fuji Firepower ReviewEdit

The Fuji Firepower Review (富士総合火力演習) is the GSDF's largest annual live-fire drill. It began in 1961 and is open to the public since 1966 for the purpose of deepening public understanding of the SDF. On August 26, 2018 it was held in front of the defense minister and 24,000 spectators at the East Fuji Maneuver Area in Gotemba near the foot of Mount Fuji. That was the first time that the Amphibious Rapid Deployment Brigade participated. The drill was based on a scenario of Japanese troops being deployed to recover far-flung islands from enemy forces. It involved about 2,400 troops, 80 tanks and armored vehicles, 60 artillery shells and 20 helicopters and fighter jets.[75]
