ORIGIN

Main article: Naval history of Japan
Japan
Naval battle of Dan-no-Ura in 1185

Japan
Japan
has a long history of naval interaction with the Asian continent, involving the 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
Japan
by Kublai Khan
Kublai Khan
in 1274 and 1281, Japanese wakō became very active in plundering the coast of the Chinese Empire . A 16th-century Japanese atakebune coastal warship.

Japan
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
Japan
may have developed one of the world's first ironclad warships, when Oda Nobunaga
Oda Nobunaga
(a Japanese daimyo ) had six iron-covered Oatakebune made in 1576.

In 1588, Toyotomi Hideyoshi
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
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 shogunate
Tokugawa shogunate
, 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 Shogunate, mainly for Southeast Asian trade.

IMPERIAL JAPANESE NAVY

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

From 1868, the restored Meiji Emperor continued with reforms to industrialize and militarize Japan
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
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. In July 1869, the Imperial Japanese Navy
Navy
was formally established, two months after the last military engagement of the Boshin War – 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. This formed the core of the new Imperial Japanese Navy.

An 1872 edict officially separated the Japanese Navy
Navy
from the Japanese Army. Politicians like Enomoto Takeaki set out to use the Navy
Navy
to expand to the islands south of Japan
Japan
in similar fashion to the Army's northern and western expansion. The Navy
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
Navy
expand and incorporate many different islands into the Japanese Empire, including Iwo Jima
Iwo Jima
in 1889. The navy continued to expand and incorporate political influence throughout the early twentieth century.

JAPANESE MARITIME SELF-DEFENSE FORCE

Yamato was a potent symbol of the Imperial Japanese Navy
Navy

Following Japan's defeat in World War II, the Imperial Japanese Navy was dissolved by the Potsdam Declaration acceptance. Ships were disarmed, and some of them, such as the 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, initially under the control of the Second Bureau of the Demobilization Ministry. 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
Japan
is that this article allows for military forces to be kept for the purposes of self-defense. Due to Cold War
Cold War
pressures, the United States was also happy for Japan
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
Japanese Self-Defense Force
(JSDF), following the passage of the 1954 Self-Defense Forces Law.

The first ships in the JMSDF were former U.S. Navy
Navy
destroyers, transferred to Japanese control in 1954. In 1956, the JMSDF received its first domestically produced destroyer since World War II, Harukaze . Due to the Cold War
Cold War
threat posed by the Soviet Navy
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 4 minesweepers, a fleet oiler (JDS Tokiwa ) and a minesweeping tender (JDS Hayasse) to the Persian Gulf in the aftermath of the Gulf War
Gulf War
, under the name of Operation Gulf Dawn, to clear mines sown by Saddam Hussein
Saddam Hussein
's defending forces; and starting with a mission to Cambodia in 1993 when JSDF personnel were supported by JDS Towada , it has been active in a number of UN-led peace keeping operations throughout Asia. In 1993, it commissioned its first Aegis -equipped destroyer, 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 UN-led Operation Enduring Freedom
Operation Enduring Freedom
.

With an increase in tensions with North Korea
North Korea
following the 1993 test of the Nodong-1
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-equipped destroyers. The JMSDF, along with the Japan
Japan
Coast Guard , has also been active in preventing North Korean infiltrators from reaching Japan
Japan
and in December 2001, engaged and sank a North Korean spy ship .

TODAY

CAPABILITIES AND RECENT DEVELOPMENTS

October 20, 2016, a meeting between Adm Tomohisa Takei , Adm John M. Richardson , Adm Sir Philip Jones ,in United States Department of Defense . A RIM-161 Standard Missile 3 launched from JDS Kongō , an Aegis destroyer .

The JMSDF has an official strength of 50,000 personnel, but presently numbers around 50,800 active personnel. As a result of continuing effective defense investment due to Japan's economic development and an end to the Cold War, The JMSDF is currently the world's fifth largest naval power. Japan
Japan
has the seventh largest Exclusive Economic Zone (EEZ) in the world, 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 warfare and minesweeping capabilities. Defense planners believe the most effective approach to combating hostile submarines entails mobilizing all available weapons, including surface combatants, submarines, patrol planes , and helicopters . Historically the Japan
Japan
Air Self-Defense Force (JASDF) has been relied on to provide air cover at sea, a role that is subordinate to the JASDF's primary mission of air defense of the home islands. Extended patrols over sea lanes are beyond the JASDF's current capabilities.

The Japanese fleet's capacity to provide ship-based antiaircraft warfare protection is limited by the absence of aircraft carriers , though its destroyers and frigates equipped with the Aegis combat system provide a formidable capability in antiaircraft and antimissile warfare . 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. JS Izumo, an Izumo-class helicopter destroyer

In August 2003, a new "helicopter carrier" 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 a helicopter carrier by Lloyd\'s Register — similar to the United Kingdom
United Kingdom
's HMS Ocean . It has been widely argued about whether an aircraft carrier of any kind would be technically prohibited by Article 9 of the Japanese Constitution , since aircraft carriers are generally considered offensive weapons. In a Japanese Diet budget session in April 1988, the chief of the Japanese Defense Agency , Tsutomu Kawara , said, "The Self-Defense Forces are not allowed to possess ICBMs (intercontinental ballistic missiles ), strategic bombers , or attack aircraft carriers."

Historically, up through about 1975 in the U.S. Navy
Navy
, the large-scale carriers had been classified as "attack aircraft carriers" and the smaller carriers as "anti-submarine aircraft carriers ." Since helicopter carriers have very little built-in attack capability and they primarily fulfill roles such as defensive anti-submarine warfare, the Japanese government continues to argue that the prohibition does not extend to the new helicopter carriers.

In November 2009, the JMSDF announced plans for an even larger "helicopter carrier", the Izumo-class helicopter destroyer . The first one of these ships was laid down in 2012 and was launched on 6 August 2013.

The submarine fleet of the JMSDF consists of some of the most technologically advanced diesel-electric submarines in the world. This is due to careful defense planning in which the submarines are routinely retired from service ahead of schedule and replaced by more advanced models. In 2010 it was announced that the Japanese submarine fleet would be increased in size for the first time in 36 years.

After a meeting between the Japanese Foreign Minister and U.S. Ambassador to Japan
Japan
on 4 March 2014, the Japanese Defense Ministry and U.S. Department of Defense announced they would hold studies for the joint development of the littoral vessel under the bilateral Mutual Defense Assistance agreement. The vessel is planned to be a high-speed trimaran designed for operations in shallow coastal waters capable of carrying helicopters, possibly a lighter variant of the American 3,000 tonne (3,300 short ton) Littoral Combat Ship . The study is in response to the growth of the Chinese People\'s Liberation Army Navy and budgetary issues with the U.S. military that may affect their ability to operate in the Pacific. The J-LCS would be used to intervene during Chinese ship incursions near the Senkaku Islands and other contested areas in the East China Sea
East China Sea
, and possibly counter similar Chinese vessels like the Type 056 corvette and Type 022 missile boat . A 1,000 tonnes (980 long tons; 1,100 short tons) J-LCS with an enlarged hull could operate the SH-60K anti-submarine helicopter or the MCH-101 airborne mine countermeasures (AMCM) helicopter.

Mission In The Indian Ocean

Destroyers and combat support ships of Japan
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). 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 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.

In January 2010, the defense minister ordered the JMSDF to return from the Indian Ocean, fulfilling a government pledge to end the eight-year refueling mission. Prime Minister Yukio Hatoyama

The JMSDF is commanded by the Chief of the Maritime Staff (currently Katsutoshi Kawano ). Its structure consists of the Maritime Staff Office, the Self Defense Fleet, five regional district commands, the air-training squadron and various support units, such as hospitals and schools. The Maritime Staff Office, located in Tokyo, serves the Chief of Staff in commanding and supervising the force.

The Self-Defense Fleet, headquartered at Yokosuka
Yokosuka
, consists of the JMSDF's military shipping. It is composed of four Escort Flotillas (based in Yokosuka
Yokosuka
, Sasebo , Maizuru and Kure ), the Fleet Air Force headquartered at Atsugi , two Submarine

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 or 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
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.

CULTURE AND NAMING CONVENTIONS

Main article: Gosei (meditation)

Although Japan's Ground Self-Defense Force has almost dropped traditions associated with the Imperial Japanese Army save for the march music tradition (Review March is the official march of the IJA and today's JGSDF), the JMSDF has maintained these historic links with the Imperial Japanese Navy
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 as that used by the IJN. Also, the JMSDF tradition of eating Japanese curry every Friday lunch originated with the IJN. The JMSDF still uses the Warship March, the old service march of the IJN, as its official service march. It also maintains the IJN bugle calls tradition, as every ship and shore establishment command maintain a platoon or squad of bugle players.

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 upgrade of the Japanese Defense Agency to the Ministry of Defense.

Ships of the JMSDF, known as JAPAN SHIPS (自衛艦; Ji'ei-Kan), are classified according to the following criteria:

RECRUITMENT AND TRAINING

JDS Kongō (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.
