The Japan Maritime Self-Defense Force (海上自衛隊, Kaijō Jieitai), or JMSDF, is the naval branch of the Japan Self-Defense Forces, tasked with the naval defense of Japan. It was formed following the dissolution of the Imperial Japanese Navy (IJN) after World War II.[3] The JMSDF has a large fleet and its main tasks are to maintain control of the nation's sea lanes and to patrol territorial waters. It has also stepped up its participation in UN-led peacekeeping operations (PKOs) and Maritime Interdiction Operations (MIOs).

Japan has a long history of naval interaction with the Asian continent, involving transportation of troops, starting at least with the beginning of the Kofun period in the 3rd century. Following the attempts at Mongol invasions of Japan by Kublai Khan in 1274 and 1281, Japanese wakō became very active in plundering the coast of the Chinese Empire.

Japan undertook major naval building efforts in the 16th century, during the Warring States period, when feudal rulers vying for supremacy built vast coastal navies of several hundred ships. Around that time, Japan may have developed one of the world's first ironclad warships, when Oda Nobunaga (a Japanese daimyo) had six iron-covered Oatakebune made in 1576.[4][5]

In 1588, Toyotomi Hideyoshi issued a ban on Wakō piracy; the pirates then became vassals of Hideyoshi and comprised the naval force used in the Japanese invasion of Korea.

Japan built her first large ocean-going warships in the beginning of the 17th century, following contact with European countries during the Nanban trade period. In 1613, the Daimyo of Sendai, in agreement with the Tokugawa Bakufu, built the Date Maru. This 500 ton galleon-type ship transported the Japanese embassy of Hasekura Tsunenaga to the Americas and Europe. From 1604 onwards, about 350 Red seal ships, usually armed and incorporating European technology, were also commissioned by the Bakufu, mainly for Southeast Asian trade.

Creation of the Imperial Japanese Navy

The British-built Ryūjō was the flagship of the Imperial Japanese Navy until 1881.

From 1868, the restored Meiji Emperor continued with reforms to industrialize and militarize Japan to prevent the United States and European powers from overwhelming it. On 17 January 1868, the Ministry of Military Affairs was established, with Iwakura Tomomi, Shimazu Tadayoshi and Prince Komatsu-no-miya Akihito as the First Secretaries.

On 26 March 1868, the first Naval Review was held in Japan (in Osaka Bay), with 6 ships from the private domainal navies of Saga, Chōshū, Satsuma, Kurume, Kumamoto and Hiroshima participating. The total tonnage of these ships was 2252 tons, far smaller than the tonnage of the single foreign vessel (from the French Navy) that also participated. The following year, in July 1869, the Imperial Japanese Navy was formally established, two months after the last military engagement of the Boshin War. In July 1869, the private navies of the Japanese nobles were abolished, and their 11 ships were added to the 7 surviving vessels of the defunct Tokugawa bakufu navy, including the Kankō Maru, Japan's first steam warship.[6] This formed the core of the new Imperial Japanese Navy.

An 1872 edict officially separated the Japanese Navy from the Japanese Army. Politicians like Enomoto Takeaki set out to use the Navy to expand to the islands south of Japan in similar fashion to the Army's northern and western expansion. The Navy sought to upgrade its fleet to a blue water navy and used cruises to expand the Japanese consciousness on the southern islands. Enomoto's policies helped the Navy expand and incorporate many different islands into the Japanese Empire, including Iwo Jima in 1889. The navy continued to expand and incorporate political influence throughout the early twentieth century.[7]

Formation of the Japanese Maritime Self-Defense Force

Yamato was a potent symbol of the Imperial Japanese Navy

Following the defeat of Japan during World War II, the Imperial Japanese Navy was dissolved by the Potsdam Declaration acceptance. Ships were disarmed, and some of them, such as battleship Nagato, were taken by the Allied Powers as reparation. The remaining ships were used for repatriation of the Japanese soldiers from abroad and also for minesweeping in the area around Japan. The minesweeping fleet was eventually transferred to the newly formed Maritime Safety Agency, which helped maintain the resources and expertise of the navy.

Japan's 1947 Constitution was drawn up after the conclusion of the war, Article 9 specifying that "The Japanese people forever renounce war as a sovereign right of the nation and the threat or use of force as a means of settling international disputes." The prevalent view in Japan is that this article allows for military forces to be kept for the purposes of self-defense. Due to Cold War pressures, the United States was also happy for Japan to provide part of its own defense, rather than have it fully rely on American forces.

In 1952, the Coastal Safety Force was formed within the Maritime Safety Agency, incorporating the minesweeping fleet and other military vessels, mainly destroyers, given by the United States.

In 1954, the Coastal Safety Force was separated, and the JMSDF was formally created as the naval branch of the Japanese Self-Defense Force (JSDF), following the passage of the 1954 Self-Defense Forces Law.

The first ships in the JMSDF were former US Navy destroyers, transferred to Japanese control in 1954. In 1956, the JMSDF received its first domestically produced destroyer since World War II, the Harukaze. Due to the Cold War threat posed by the Soviet Navy's sizable and powerful submarine fleet, the JMSDF was primarily tasked with an anti-submarine role.

Post Cold War

Following the end of the Cold War, the role of the JMSDF has vastly changed. In 1991, after much international pressure, the JMSDF dispatched minesweepers to the Persian Gulf in the aftermath of the Gulf War to clear mines sown by Saddam Hussein's defending forces;[8] and starting with a mission to Cambodia in 1993 when JSDF personnel were supported by the JDS Towada,[8] it has been active in a number of UN-led peace keeping operations throughout Asia. In 1993, it also commissioned its first Aegis-equipped destroyer, the DD173 Kongō. It has also been active in joint naval exercises with other countries, such as the United States. The JMSDF has dispatched a number of its destroyers on a rotating schedule to the Indian Ocean in an escort role for allied vessels as part of the US-led Operation Enduring Freedom.

Following an increase in tensions with North Korea following the 1993 test of the Nodong-1 missile and the 1998 test of the Taepodong-1 missile over northern Japan, the JMSDF has stepped up its role in air defense. A ship-based anti-ballistic missile system was successfully test-fired on 18 December 2007 and has been installed on Japan's Aegis-class destroyers. The JMSDF along with Japan Coast Guard has also been active in preventing North Korean infiltrators from reaching Japan and at one time, engaged and sank a North Korean spyship in 2001.

Strength

Further information: List of active ships of the Japan Maritime Self-Defense Force

The JMSDF has an official strength of 46,000 personnel, but currently numbers around 45,800 personnel.

Ships

The ship prefix JDS (Japanese Defense Ship) was used until 2008, at which time JMSDF ships started using the prefix JS (Japanese Ship) to reflect the upgrading of the Japanese Defense Agency to the Ministry of Defense.

The JMSDF operates some 110 major warships, including four helicopter destroyers ("Helicopter carriers"), eight guided-missile destroyers, twenty-nine small-destroyers ("frigates"), three destroyer-escorts ("light-frigates") and sixteen attack submarines (SSK).[9] The fleet has a total displacement of approx. 432,000 tons.[10] It also has 179 fixed-wing aircraft and 135 helicopters. Most of these aircraft are used in antisubmarine and mine warfare operations.[11]

Capabilities and recent developments

A RIM-161 Standard Missile 3 launched from JDS Kongo, an Aegis destroyer.

Japan has the 7th largest Exclusive Economic Zone (EEZ) in the world,[18] and the JMSDF is responsible for protecting this large area. As an island nation, dependent on maritime trade for the majority of its resources, including food and raw materials, maritime operations are a very important aspect of Japanese defense policy.

The JMSDF is known in particular for its anti-submarine and mine-sweeping capability. Defense planners believe the most effective approach to combating submarines entails mobilizing all available weapons, including surface combatants, submarines, aircraft and helicopters. Historically the JASDF has been relied upon to provide air cover at sea, a role that is subordinate to JASDF's primary mission of air defense of the home islands. Extended patrols over sea lanes are beyond the JASDF's current capabilities.

The fleet's capacity to provide ship-based anti-air protection is limited by the absence of aircraft carriers, though its Aegis-equipped destroyers provide a formidable capability in anti-air warfare. The fleet is also short of underway replenishment ships and generally deficient in all areas of logistic support. These weaknesses seriously compromise the ability of the JMSDF to fulfill its mission and operate independently of the United States Air Force and the United States Seventh Fleet. However, these capabilities are force multipliers, allowing force projection of Japan's sizable destroyer and frigate force far from home waters, and acquiring them is contentious considering Japan's "passive" defense policy.

JDS Hyuga, a Hyūga class helicopter carrier

In August 2003, a new "helicopter destroyer" class was ordered, the Hyūga class helicopter destroyer. The size and features of the ship, including a full length flight deck, will result in it being classified as either an amphibious assault ship, or helicopter carrier by Lloyd's Register, similar to HMS Ocean (L12). It has been widely disputed if a carrier of any sort would be technically prohibited by Article 9 of the Japanese Constitution, as carriers are generally considered offensive weapons. In an April 1988 Diet budget session, then Defense Agency chief Tsutomu Kawara said that "The Self-Defense Forces are not allowed to possess ICBMs (intercontinental ballistic missiles), strategic bombers, or attack aircraft carriers."[citation needed]

Until the 1970s in the US Navy, large-scale flattops had been categorized as "attack aircraft carriers" and small flattops as "anti-submarine aircraft carriers." Since helicopter carriers have little organic attack capability and primarily fulfill roles including logistics and transport, the government continues to argue that the prohibition does not extend to the new ship.

In November 2009 the JMSDF announced plans for a even larger "helicopter carrier" and the first ship was laid down in 2012.[19][20][21]

The JMSDF's submarine fleet consists of one of the most technologically advanced and capable diesel-electric forces in the world. This is due to careful defense planning in which boats are routinely retired ahead of schedule and replaced by increasingly advanced models.[22] In 2010 it was announced that the Japanese submarine fleet would be increased for the first time in 36 years.[2]

International activities

Mission in the Indian Ocean

Destroyers and combat support ships of Japan Maritime Self-Defense Force were dispatched to the Indian Ocean from 2001 to 2008 to participate in OEF-MIO (Operation Enduring Freedom-Maritime Interdiction Operation).[23] Their mission is to prevent the marine transportation of illegal weapons and ammunition, and the drugs which fund terrorist activity. Since 2004, the JMSDF has provided ships of foreign forces with fuel for their ships and ship-based helicopters, as well as fresh water.

This was the third time Japanese military vessels had been dispatched overseas since World War II, following the deployments of a mine-sweeping units during the Korean War and the Persian Gulf War. The law enabling the mission expired on 2 November 2007, and the operation was temporarily canceled due to a veto of a new bill authorizing the mission by the opposition-controlled upper chamber of the Japanese Diet. A new law was subsequently passed when the lower chamber overruled the veto, and the mission was resumed.

In January 2010, the defense minister ordered the Japanese navy to return from the Indian Ocean, fulfilling a government pledge to end the eight-year refueling mission. Prime Minister Yukio Hatoyama refused to renew the law authorizing the mission, ignoring requests from the American government for continuation.[24]

Mission in Somalia

In May 2010, Japan announced its intention to build a permanent naval base in Djibouti, from which it will conduct operations to protect merchant shipping from Somali pirates.[25]

Military exercises and exchanges

The JMSDF and the U.S. Navy frequently carry out joint exercises and "U.S. Navy officials have claimed that they have a closer daily relationship with the JMSDF than any other navy in the world".[26] The JMSDF participates in RIMPAC, the annual multi-national military exercise near Hawaii that has been hosted by the U.S. Navy since 1980. The JMSDF dispatched a ship to the Russian Vladivostok harbor in July in 1996 to participate in the Russian Navy's 300th anniversary naval review. Vladimir Vinogradov came by ship to the Tokyo harbor in June 1997. The JMSDF has also conducted joint naval exercises with the Indian Navy.

JMSDF District Forces

Escort Forces

Each Escort force is formed as an 8–8 fleet of 8 destroyers and 8 on-board helicopters, a modification of the old Japanese Navy fleet layouts of 8 battleships and 8 cruisers. Each force is composed of one helicopter destroyer (DDH) acting as a command ship, two guided-missile destroyers (DDG) and 5 standard or ASW destroyers (DD).

  • First Escort Force – Yokosuka
  • Second Escort Force – Sasebo
  • Third Escort Force – Maizuru
  • Fourth Escort Force – Kure

District Forces

Five district units act in concert with the fleet to guard the waters of their jurisdictions and provide shore-based support. Each district is home to a major JMSDF base and its supporting troops and staff. Furthermore, each district is home to one to two regional escort squadrons, composed of two to three destroyers or destroyer escorts (DE). The destroyers tend to be of older classes, mainly former escort force ships. The destroyer escorts, on the other hand, tend to be purpose built vessels. Each district also has a number of minesweeping ships.

Fleet Air Force

The Fleet Air Force is tasked with patrol, ASW and rescue tasks. It is composed primarily of 7 aviation groups. Prominent bases are maintained at Kanoya, Hachinohe, Atsugi, Naha, Tateyama, Oomura and Iwakuni. The Fleet Air Force is built up mainly with patrol aircraft such as the Lockheed P-3 Orion, rescue aircraft such as the US-1A and helicopters such as the SH-60J. In the JMSDF, helicopters deployed to each escort force are actually members of Fleet Air Force squadrons based on land.

Special Forces

Special Forces units consist of the following:

Culture and naming conventions

Main article: Gosei (meditation)

Although Japan's Ground Self-Defense Force has dropped traditions association with the Imperial Japanese Army, the JMSDF has maintained these historic links with the Imperial Japanese Navy (IJN). Today's JMSDF continues to use the same martial songs, naval flags, signs and technical terms as the IJN. For example, the official flag of the JMSDF is the same that was used by the IJN. Also, the JMSDF tradition of eating curry every Friday originated with the IJN.

Ships of the JMSDF, known as Japan Defense Ships (自衛艦; Ji'ei-Kan), are classifed according to the following criteria:

Recruitment and training

JDS Kongo (DDG 173)

JMSDF recruits receive three months of basic training followed by courses in patrol, gunnery, mine sweeping, convoy operations and maritime transportation. Flight students, all upper-secondary school graduates, enter a two-year course. Officer candidate schools offer six-month courses to qualified enlisted personnel and those who have completed flight school.

Officer Candidate School

Graduates of four-year universities, the four-year National Defense Academy, and particularly outstanding enlisted personnel undergo a one-year officer course at the Officer Candidate School at Etajima (site of the former Imperial Naval Academy). The JMSDF also operates a staff college in Tokyo for senior officers.

The large volume of coastal commercial fishing and maritime traffic around Japan limits in-service sea training, especially in the relatively shallow waters required for mine laying, mine sweeping and submarine rescue practice. Training days are scheduled around slack fishing seasons in winter and summer—providing about ten days during the year.

The JMSDF maintains two oceangoing training ships and conducted annual long-distance on-the-job training for graduates of the one-year officer candidate school.[27]
