Japan navy strength

It was the third largest navy in the world.

However, after a series of defeats it lost control of the Western Pacific and collapsed by the end of the war.

The naval air service was one of the most potent air forces in the world before its destruction in World War II. Nearly all were sent to the bottom of the sea by the war's end. Yamatothe heaviest battleship in history, in Yamatothe heaviest and most heavily armed battleship in history, was launched in Good and bad on a krone baler second half of World War II saw the last battleship duels.

In the Battle of Guadalcanal on 15 Novemberthe U. Nevertheless, the Battle off Samar on 25 October during the Battle of Leyte Gulf showed battleships could still be useful.

Miraculously for the Americans, only one escort carrier, two destroyers, and one destroyer escort were lost in this action. Ultimately, the maturity of air power spelled doom for the battleship. Battleships in the Pacific ended up primarily performing shore bombardment and anti-aircraft defense for the carriers. Yamato and Musashi were sunk by air attacks long before coming in gun range of the American fleet.

Japan put particular emphasis on aircraft carriers. The Imperial Japanese Navy started the Pacific War with 10 aircraft carriers, [5] the largest and most modern carrier fleet in the world at that time.

There were seven American aircraft carriers at the beginning of hostilities, only three operating in the Pacific; and eight British aircraft carriers, of which a single one operated in the Indian Ocean. Another conversion project, Shinanowas based on an incomplete Yamato -class super battleship and became the largest-displacement carrier of World War II. The IJN also attempted to build a number of fleet carriers, though most of these projects were not completed by the end of the war.

This came as a nasty surprise to the Allies, who had generally underestimated Japanese technical capabilities. The Japanese had reassessed their naval needs in the mids and, placing an emphasis on ship and weapons technology and night fighting expertise, developed a completely new destroyer design. Subsequent development from one destroyer class to the next was not, however, a smooth progression.

Aside from the usual changes arising from experience, serious design faults also came to light and naval treaties imposed restrictions.The JSDF is ranked as the world's fourth most-powerful military in conventional capabilities by a Credit Suisse report in and it has the world's eighth-largest military budget. Tensions, particularly with North Korea[9] have reignited the debate over the status of the JSDF and its relation to Japanese society.

Japan was deprived of any military capability after being defeated by the Allies in World War II and was forced to sign a surrender agreement presented by General Douglas MacArthur in It was occupied by U. With rising tensions in Europe and Asia due to the Cold War, 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 as occupation troops began to be moved to the Korean War —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. The treaty allowed United States forces stationed in Japan to deal with external aggression against Japan while Japanese ground and maritime forces would deal with internal threats and natural disasters.

It permitted the United States to act for the sake of maintaining peace in East Asia and exert its power on Japanese domestic quarrels. Accordingly, in mid, the National Police Reserve was expanded tomen and named the National Safety Forces.

Under Article 9 of the United States—written constitutionJapan had to forever renounce war as an instrument for settling international disputes and declared that Japan will never again maintain "land, sea, or air forces or another war potential.

Air Force, announced on 6 Januarythat 85 aircraft would be turned over to the fledgling Japanese air force on about 15 January, the first equipment of the new force. On 19 Januarythe amended Treaty of Mutual Cooperation and Security between the United States and Japan corrected the unequal status of Japan in the treaty by adding mutual defense obligations. The U. The US is also prohibited from exerting any power on domestic issues within Japan.

Because it states that any attack against Japan or the United States in Japanese territory would be dangerous to each country's peace and safety. The revised treaty requires Japan and the United States to maintain capacities to resist common armed attacks. Thus it explains the need for US military bases in Japan. This established a security alliance between Japan and the United States.

The treaty has lasted longer than any other alliance between two great powers since the Peace of Westphalia treaties in InJapanese 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. Although possession of nuclear weapons is not explicitly forbidden in the constitution, Japan being the only nation to experience 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 limits research, development, and use of nuclear power to peaceful uses only. Beginning innational 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 Japan ratified the Treaty on the Non-Proliferation of Nuclear Weapons adopted by the United Nations Security Council in 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 plantsJapan is generally considered to be "nuclear capable", i.

On May 28,the Regional Affairs Law was enacted. It allows Japan to automatically participate as "rear support" if the United States wages war under "regional affairs. It allows the JSDF to contribute by itself to international efforts to the prevention and eradication of terrorism. While on duty the JSDF can use weapons to protect themselves and others who come under their control.Its naval aviation corps, consisting of 10 aircraft carriers and topnotch aviators, was the most highly trained and proficient force of its kind.

Its 11 soon to be 12 battleships were among the most powerful in the world. And its surface forces, armed with the superb 24" Type 93 Long Lance torpedo, were incomparable night fighters. How and why this impressive force was eventually crushed by the U. Navy is a subject that has fascinated me practically forever. Maybe I'm just intrigued by the underdog.

The resurgence comes despite a constitution imposed by the United States after World War II that limited the country's forces to defensive purposes only. In fact, analysts say, that defensive restriction has helped make Japan's military stronger than it might have been without it. Kuehn, a professor of military history at the U. Army Command and General Staff College. And it achieved this with a military budget that is only a fraction of others powers.

The buildup comes as the country faces shifting security dynamics in the region, with a newly elected US president who looks poised to upend the diplomatic playbook and redraw the geopolitical map.

Japan's new stealth fighter jet Kuehn is not alone among analysts who rate Japan's navy, known as the Japanese Maritime Self-Defense Force, among the top five navies in the world. Kuehn said the presence of US technology like the ship-based Aegis anti-missile system, which can shoot down ballistic missiles, in Japan's fleet makes it a force hard to counter.

The anti-war, US-imposed constitution Japan found itself under after World War II may have helped Japan put together a military that might be even stronger than the one that attacked Pearl Harbor on December 7,some analysts say, because Tokyo has only had to focus on defensive capabilities and not spend money on offensive ones.

During the first six months of the war, the Imperial Japanese Navy enjoyed spectacular success inflicting heavy defeats on Allied forces, being undefeated in every battle. The campaign in the Solomon Islandsin which the Japanese lost the war of attrition, was the most decisive; they had failed to commit enough forces in sufficient time. During the Allies were able to reorganize their forces and American industrial strength began to turn the tide of the war.

Forces on Japanese held islands in Micronesia were to absorb and wear down an expected American counteroffensive. During the last phase of the war, the Japanese resorted to a series of desperate measures, including a variety of Special Attack Units which were popularly called kamikaze.

At the end of the war, the IJN had lost warships andofficers and men. At the beginning of the Pacific Warthe strategy of the Imperial Japanese Navy was underpinned by several key assumptions. The most fundamental was that just as the Russo-Japanese War had been decided by the naval Battle of Tsushima May 27—28,the war against the United States would be decided by a single decisive naval battle or Kantai Kessen.

The Japanese assumed that at the start of any conflict they would quickly seize the largely unprotected American-held Philippines. This would force the United States to undertake a drive across the Pacific to retake them. Consequently, the great decisive clash would take place somewhere in the western Pacific where the Japanese decided was the right area to stop the American advance. It was also clear to the Japanese that in order to win the decisive battle they would have to make up for their numerical disadvantage.

The first was that the Japanese would had to have the weapons and tactics to inflict severe attrition on the US Pacific Fleet before the decisive battle which would bring the Japanese to at least parity. Once at rough parity, Japanese naval units with superior speed and capable of hitting at ranges beyond the reach of the Americans and crewed by expertly trained personnel, would win the day. The naval war that Japan fought in the Pacific during reflected quite a very different strategy from the one in which the Imperial Japanese Navy had been planning and training for throughout the interwar period.

Yamamoto, virtually overnight, changed the passive wartime strategy of seizing the Philippines and waiting for an American naval advance to the western Pacific to a much more aggressive forward strategy. After the completion of the Combined Fleet's annual maneuvers in the fall ofYamamoto had directed that a study of an attack on Pearl Harbor be performed under the utmost secrecy.

By December of that year, Yamamoto had decided to conduct the Pearl Harbor operation. Yamamoto was convinced that war with the United States was inevitable, once the Japanese began any hostilities. He also believed that since a traditional victory against the United States was not possible, he had to shatter American morale and force a negotiated peace. The operation was risky as it exposed the IJN's most powerful striking force to early destruction and consequently Yamamoto had great difficulty getting his plan to attack Pearl Harbor approved by a skeptical Naval General Staff[18] as the Naval General Staff was responsible for directing operations and exercised supreme command over the navy but this is not how Yamamoto viewed the situation.

In a series of meetings on October 17—18,Yamamoto threatened to resign unless his plan was approved, with this threat brought the final approval of the plan as Yamamoto was viewed as too valuable to lose. The Japanese strategy for the coming conflict would be to fight a limited war, in which Japan would seize key objectives and then create a defensive perimeter to defeat Allied counterattacks, this would in turn would lead to a negotiated peace settlement.

Seizure of these key areas would provide a defensive perimeter and depth to deny the Allies staging areas from which to mount a counteroffensive. On December 7,the two waves of aircraft from the six carriers gained complete surprise and successfully hit their intended targets.

Forty B5N torpedo bombers were the most crucial part of the operation since they were to be targeted against the main battleships and carriers. Of the eight American battleships present in the harbor, five were subjected to torpedo attack and Japanese torpedo aircraft were responsible for the sinking of the battleships OklahomaWest Virginia and California. Additionally, torpedoes sank a target ship and a minelayer, and damaged the two light cruisers, Helena and Raleigh.

In return, costing the Japanese only five torpedo bombers. The efforts of the torpedo bombers were complemented by 49 D3A level bombers armed with 1,lb armor-piercing bombs.Its main tasks are to maintain control of the nation's sea lanes and to patrol territorial waters. 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.

Japan undertook major naval building efforts in the 16th century, during the Warring States periodwhen feudal rulers vying for supremacy built vast coastal navies of several hundred ships. 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.

This ton galleon -type ship transported the Japanese embassy of Hasekura Tsunenaga to the Americas and Europe. From onwards, about Red seal shipsusually armed and incorporating European technology, were also commissioned by the shogunate, mainly for Southeast Asian trade. Fromthe restored Meiji Emperor continued with reforms to industrialize and militarize Japan to prevent the United States and European powers from overwhelming it. The total tonnage of these ships was 2, tons, far smaller than the tonnage of the single foreign vessel from the French Navy that also participated.

An 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 The navy continued to expand and incorporate political influence throughout the early twentieth century. The Japanese victory in the Russo-Japanese War of — marks the emergence of Japan as a major military power.

Japan demonstrated that it could apply Western technology, discipline, strategy, and tactics effectively. The war concluded with the Treaty of Portsmouth. The complete victory of the Japanese military surprised world observers.

The consequences transformed the balance of power in East Asia. The Japanese seaplane carrier Wakamiya conducted the world's first successful naval-launched air raids on 5 September and during the first months of World War I from Kiaochow Bay off Tsingtao.

On 6 September was the very first air-sea battle in history. Four seaplanes bombarded German land targets. The Germans surrendered on 6 November Over the course of the war, Japan displayed many significant advances in military technology, strategy, and tactics.

Among them were the Yamato -class battleshipthe Sen-Toku submarine bomber carriers, the Mitsubishi Zero fighters, and Kamikaze bombers. Ships were disarmed, and some of them, such as the battleship Nagatowere 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.

Japan's 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.

Resurgent Japan military 'can stand toe to toe with anybody'

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.

Inthe Coastal Safety Force was formed within the Maritime Safety Agencyincorporating the minesweeping fleet and other military vessels, mainly destroyers, given by the United States.

Navy destroyers, transferred to Japanese control in It has also been active in joint naval exercises with other countries, such as the United States. There was discussion about whether an aircraft carrier would be prohibited by Article 9 of the Japanese Constitutionsince aircraft carriers are generally considered offensive weapons.There must be eliminated for all time the authority and influence of those who deceived and misled the people of Japan into embarking on world conquest, for we insist that a new order of peace, security and justice will be impossible until irresponsible militarism is driven from the world The Japanese military forces, after being completely disarmed, shall be permitted to return to their homes with the opportunity to lead peaceful productive lives.

These principles enunciated in the Potsdam Declaration formed the basis for the elimination of military power and the initial plans for the demobilization of the Japanese armed forces incidental to occupation movements. Upon the return of the surrender delegation to Japan in Augusta complex demobilization machinery went into high gear: the rapid, orderly repatriation, demobilization and disarmament of the Japanese armed forces, at home and abroad, began immediately.

In view of the Theater G-2's detailed knowledge of the strength and dispositions of the Imperial Japanese Forces and the internal structure of the General Staff and other military organs after four years of intimate combat association, the intelligence section was given a prominent role in the surrender negotiations. In the agenda of the conference, the basic conditions were laid down for demobilizing and disarming the Imperial Forces. G-2 was directed to supervise the initial demobilization and disarmament plans of the Japanese Government, to exercise GHQ supervision of subsequent developments thereunder, and to render periodical progress reports.

On the day of surrender, the Imperial Japanese Forces totaled 6, troops, an aggregate of army ground force divisions, brigades, 2 and some odd major naval units. The balance of the Japanese forces were spread in a great arc from Manchuria to the Solomons, and across the islands of the Central and Southwest Pacific. Accurate and reliable figures on total strengths at the time of surrender were unavail.

Original figures presented to General MacArthur's headquarters required continuous adjustment; and as repatriation progressed, it became apparent that hundreds of thousands of men, included in initial Japanese strength estimates, had perished prior to the conclusion of hostilities.

In the over-all picture, enormous military risks were involved in landing initially with "token" United States forces. The Japanese mainland was still potentially a colossal armed camp, and there was an obvious military gamble in landing with only two and a half divisions, then confronted by fifty-nine Japanese divisions, thirty-six brigades, and forty-five-odd regiments plus naval and air forces. The terrific psychological tension was dissolved by the relatively simple formula of preserving the existing Japanese Government, and utilizing its normal agencies to effect the complicated processes of disarmament and demobilization.

The program for the accomplishment of this tremendous task was initiated under the provisions of several key directives in August-September Supervising and planning this complicated operation required careful coordination on the part of the Occupation forces and ultimately involved practically all General Staff sections 6 and several Japanese.

Certain civil sections were also drawn into this complex picture in connection with various phases of the demobilization operation. For example, the Public Health and Welfare Section of GHQ, SCAP, cooperating with G-3, was instrumental in developing effective repatriation quarantine policies, a step which prevented the dangerous epidemics so often associated with mass movements of people.

To effect coordination and facilitate progress of the demobilization and disarmament program, each local Japanese commander was ordered to report to the senior U.

Army commander in his area for command instructions; the Japanese staff was required to produce such information as locations of regiments and all larger units, tables of organization, actual strength figures, status of demobilization, and locations and names of commanders of demobilization depots. When this information was checked against the same information submitted by the Japanese Imperial General Headquarters 8 some discrepancies were noted; for example, the Japanese failed to report twenty-three units of the tooth Air Brigade located at Takamatsu airfield on Yura Island Shikoku District.

However, through local surveillance by Occupation troops, complete demobilization was quickly carried out. Orders published by the Sixth and Eighth U. In essence they called for existing agencies such as the Japanese military, naval, and civilian police, and the senior naval and military commanders to disarm all personnel found with weapons.
