) of April 1941. The Neutrality Pact freed up forces from the border incidents and enabled the Soviets to concentrate on
their war with Germany, and the Japanese to concentrate on their southern expansion into Asia and the Pacific Ocean.
With
success at Stalingrad, and the eventual defeat of Germany becoming increasingly certain, the Soviet attitude to Japan changed, both publicly, with Stalin making speeches denouncing Japan, and covertly with the building up of forces and supplies in the Far East.

agreed that the Soviet Union would enter the war against Japan once Germany was defeated. Stalin faced a dilemma: he wanted to avoid a war on two fronts at almost any cost, yet he also saw an opportunity to secure gains in the Far East on top of those he expected in Europe. The only way Stalin could ensure these gains without a two-front war would be for Germany to capitulate before Japan.
Due to the Soviet–Japanese Neutrality Pact, the Soviets made it official policy to intern Allied aircraft and crews who landed in Soviet territory following operations against Japan. However, the Soviets and Western Allies soon came to informal arrangements to circumvent official policy. Under the auspices of
Lend Lease
Lend-Lease, formally the Lend-Lease Act and introduced as An Act to Promote the Defense of the United States (), , the Allies officially transferred aircraft of the same types interred by the Soviets in the Far East, the mutual understanding being that the Soviets would also be able use "interned" Allied aircraft against the Germans without revealing their true origins. In return, Allied airmen held in the Soviet Union were usually transferred to camps near

or other Allied-controlled territory, from where they were typically allowed to "escape" after some period of time. Nevertheless, the Soviet buildup in the Far East steadily accelerated even before the defeat of Germany. By early 1945 it had become apparent to the Japanese that the Soviets were preparing to invade Manchuria, though they correctly calculated that they were unlikely to attack prior to Germany's defeat. In addition to their problems in the Pacific, the Japanese realised the need to determine when and where a Soviet invasion would occur.
At the Yalta Conference in February 1945, Stalin secured Roosevelt's acceptance of Soviet expansion in the Far East, in return for agreeing to enter the Pacific war within two or three months after the defeat of Germany. By the middle of March, things were not going well in the Pacific for the Japanese, and they had withdrawn their elite troops from Manchuria to support actions in the Pacific. Meanwhile, the Soviets continued their Far Eastern buildup, having decided that they did not wish to renew the Neutrality Pact. The terms of the Pact required a notification of expiry 12 months ahead of time, so on 5 April 1945 the Soviets ostensibly obliged, informing the Japanese that they did not wish to renew the treaty.

) This caused the Japanese considerable concern, but the Soviets went to great efforts to assure the Japanese that the treaty would still be in force for another twelve months, and that the Japanese had nothing to worry about.
[
Germany surrendered just after midnight Moscow time on 9 May 1945, meaning that if the Soviets were to honour the agreement at Yalta, they would need to enter the war with Japan by 9 August. The situation continued to deteriorate for the Japanese, now the only Axis power left in the war. They were keen to stay at peace with the Soviets,][Boris Nikolaevich Slavinskiĭ, The Japanese-Soviet Neutrality Pact: A Diplomatic History 1941–1945, Translated by Geoffrey Jukes, 2004, Routledge.]

and ultimately to achieve an end to the war. Since Yalta, they had repeatedly tried to convince the Soviets to extend the Neutrality Pact, as well as attempting to enlist them to mediate peace negotiations with the Western Allies. The Soviets did nothing to discourage these overtures, instead happy to draw out the process for as long as possible whilst continuing to prepare their invasion forces.[ One of the goals of Admiral Baron Suzuki's cabinet upon taking office in April was to try to secure any peace terms whatsoever short of unconditional surrender.][Jones, F. C. "Manchuria since 1931", 1949, Royal Institute of International Affairs, London. p. 221] In late June, they once again approached the Soviets, inviting them to mediate with the Western Allies in support of Japan, providing them with specific proposals. In exchange, they were prepared to offer the Soviets very attractive territorial concessions. Stalin ostensibly expressed interest, and the Japanese now awaited an official Soviet response, even as the Soviets continued to deliberately avoid providing one. The Potsdam Conference was held from 16 July to 2 August; on 24 July the Soviet Union recalled all its embassy staff and families from Japan. On 26 July the conference produced the Potsdam Declaration

As a result, the Japanese forces in Manchuria and Korea had essentially been reduced to a light-infantry counter-insurgency force with limited mobility and limited ability to fight a conventional land war against a coordinated enemy. In fact, only six of the Kwantung Army's divisions existed prior to January 1945. Accordingly, the Japanese regarded none of the Kwantung Army's units as combat ready, with some units being declared less than 15% ready.
The Imperial Japanese Navy
The Imperial Japanese Navy (IJN; Kyūjitai: Shinjitai: ' 'Navy of the Greater Japanese Empire', or ''Nippon Kaigun'', 'Japanese Navy') was the navy of the Empire of Japan from 1868 to 1945, Potsdam Declaration, when it was dissolved followin ...
did not contribute to the defense of Manchuria, the occupation of which it had always opposed on strategic grounds. Additionally, by the time of the Soviet invasion, the few remnants of its fleet were stationed and tasked for the defense of the Japanese home islands in the event of an invasion by American forces.
Compounding their problems, the Japanese military made many wrong assumptions and major mistakes, most significantly:
*They wrongly assumed that any attack coming from the west would follow either the old railway line to Hailar, or head into Solun from the eastern tip of Mongolia. The Soviets did attack along those routes, but their main attack from the west went through the supposedly impassable Greater Khingan range south of Solun and into the center of Manchuria.

failed to determine the nature, location and scale of the Soviet buildup in the Soviet Far East. Based upon an initial underestimation of Soviet strength and on the monitoring of Soviet traffic on the Trans-Siberian railway, the Japanese believed that the Soviets would not have sufficient forces in place for an offensive before the end of August 1945, and that an attack was most likely in the autumn of 1945 or in the spring of 1946.
Due to the withdrawal of the Kwantung Army's elite forces for redeployment into the Pacific Theater, the Japanese made new operational plans during the summer of 1945 for the defence of Manchuria against a seemingly inevitable Soviet attack. These called for redeploying the bulk of available forces from the border areas; the borders were to be held lightly and delaying actions were to be fought while the main force was to hold the southeastern corner in strength (so defending Korea from attack).[Hayashi, S. (1955). Vol. XIII – Study of Strategic and Tactical peculiarities of Far Eastern Russia and Soviet Far East Forces. Japanese Special Studies on Manchuria. Tokyo, Military History Section, Headquarters, Army Forces Far East, US Army.]
Further, the Japanese had observed Soviet activity only on the Trans-Siberian railway and along the east Manchurian front, and accordingly prepared for an invasion from the east. They believed that when an attack occurred from the west, the redeployed forces would be able to deal with it.
Although the Japanese redeployment in Manchukuo had begun, it was not due for completion until September 1945, and hence the Kwantung Army was in the midst of redeploying when the Soviets launched their attack simultaneously on all three fronts.
Campaign
The operation was carried out as a classic double pincer movement over an area the size of the entire Western European theatre of World War II. In the western pincer, the Red Army advanced over the deserts and mountains from Mongolia, far from their resupply railways. This confounded the Japanese military analysis of Soviet logistics, and the defenders were caught by surprise in unfortified positions. The Kwantung Army commanders were engaged in a planning exercise at the time of the invasion, and were away from their forces for the first eighteen hours of conflict.
The Russians treated the Japanese with the utmost cruelty after their deadly attack on Japan's Kwantung Army in Manchuria just days before Japan's surrender. Japanese forces were overwhelmed by Soviet attacks. Soviet paratroopers destroyed the Kwantung Army from behind its own lines, while Japanese anti-tank shells bounced off the sides of Soviet tanks. The Japanese forces in Manchuria retreated in fear.
Japanese troops and able-bodied Japanese men in Manchuria were taken prisoner by the Russians and transported to labor camps in Siberia, where many Japanese men would die. From the Russians' perspective, this was seen as revenge for Russia's defeat in the Russo-Japanese War

by Japanese evacuees of Manchuria, creating panic among the Japanese population; however, the Russians honored their agreement with Chiang Kai-shek by not entering China proper.
Japanese communication infrastructure was poor, and the Japanese lost communication with forward units very early on. However, the Kwantung Army had a formidable reputation as fierce and relentless fighters, and even though understrength and unprepared, put up strong resistance at the town of Hailar which tied down some of the Soviet forces. The Japanese defenders held out until 18 August, when 3,827 survivors surrendered. At the same time, Soviet airborne units seized airfields and city centers in advance of the land forces, and aircraft ferried fuel to those units that had outrun their supply lines.
Due to Japanese 37mm and 47mm anti-tank guns being only suitable for fighting light Soviet tanks, Japanese forces decided to use suicide bomber squads strapped with grenades and explosives as their main improvised anti-tank weapon.

It made no direct reference to a surrender of Japan, instead stating that the government had been instructed to accept the terms of the Potsdam Declaration fully. This created confusion in the minds of many listeners who were not sure if Japan had surrendered. The poor audio quality of the radio broadcast, as well as the formal courtly language in which the speech was composed, worsened the confusion.
The Imperial Japanese Army Headquarters did not immediately communicate the cease-fire order to the Kwantung Army, and many elements of the army either did not understand it, or ignored it. Hence, pockets of fierce resistance from the Kwantung Army continued, and the Soviets continued their advance, largely avoiding the pockets of resistance, reaching Mukden, Changchun and Qiqihar

Aftermath
The invasion of Manchuria was a factor that contributed to the surrender of Japan and the end of World War II.
In September 1945, the Chinese Communist Party

(CCP) dispatched soldiers to Soviet-occupied Manchuria. The CCP obtained Japanese arms with Soviet help. The Soviet stance regarding the CCP and the Chinese Nationalists oscillated during this period, and in November 1945 the Soviet Union requested that the CCP withdraw from major cities in Manchuria.
The Soviet occupation of Manchuria, along with the northern portions of the Korean Peninsula, allowed for parts of those regions to be transferred by the Soviet Union into the control of local communists after the Soviet withdrawal in 1946 in spite of a 1945 agreement signed between the Soviets and the Kuomintang
The Kuomintang (KMT) is a major political party in the Republic of China (Taiwan). It was the one party state, sole ruling party of the country Republic of China (1912-1949), during its rule from 1927 to 1949 in Mainland China until Retreat ...

Several thousand Japanese who were sent as colonizers to Manchukuo and Inner Mongolia were left behind in China. The majority of Japanese left behind in China were women, and these Japanese women mostly married Chinese men and became known as "stranded war wives" (zanryu fujin). Because they had children fathered by Chinese men, Japanese women were not allowed to bring their Chinese families back with them to Japan, so most of them stayed. Japanese nationality laws allowed only children fathered by Japanese fathers to become Japanese citizens.

War crimes
During the invasion of Manchuria, Soviet soldiers killed and raped Japanese civilians. The most famous example was the Gegenmiao massacre, Soviet soldiers from an armoured unit massacred over one thousand Japanese women and children. Property of the Japanese were also looted by the Soviet troops.[ Soviet forces responsible for the massacre had carried out the same crimes against civilians in ]East Prussia
East Prussia was a Provinces of Prussia, province of the Kingdom of Prussia from 1772 to 1829 and again from 1878 (with the Kingdom itself being part of the German Empire from 1871); following World War I it formed part of the Weimar Republic's ...

According to Soviet historian Vyacheslav Zimonin, many Japanese settlers committed mass suicide as the Red Army approached. Mothers were forced by the Japanese military to kill their own children before being killed themselves.[ The Japanese army often took part in the killings of its civilians. The commander of the 5th Japanese Army, General Shimizu, commented that "each nation lives and dies by its own laws." Wounded Japanese soldiers who were incapable of moving on their own were often left to die as the army retreated.]
British and U.S. reports indicate that the Soviet troops that occupied Manchuria (about 700,000) also looted and terrorized the local people of Mukden and were not discouraged by Soviet authorities from "three days of rape and pillage." In Harbin, Soviet forces ignored protests from Chinese Communist Party

leaders on the mass rape and looting. There were several incidents in which Chinese police forces in Manchuria arrested or even killed Soviet troops for committing various crimes, leading to some conflicts between the Soviet and Chinese authorities in Manchuria.
During the Soviet occupation of North Korea, it was reported that Soviet soldiers committed rape against both Japanese and Korean women alike in the northern half of the Korean peninsula. Soviet soldiers also looted the property of both Japanese and Koreans living in northern Korea. The Soviets laid claim to Japanese enterprises in Manchuria and northern Korea and took valuable materials and industrial equipment.

dismisses Western accounts of Soviet violence against civilians in the Far East as exaggeration and rumor and contends that accusations of mass crimes by the Red Army inappropriately extrapolate isolated incidents regarding the nearly 2,000,000 Soviet troops in the Far East into mass crimes. According to him, such accusations are refuted by the documents of the time, from which it is clear that such crimes were far less of a problem than in Germany. Asmolov further asserts that the Soviets prosecuted their perpetrators while prosecution of German and Japanese "rapists and looters" in WWII was virtually unknown.
Japanese women in Manchukuo were repeatedly raped by Russian soldiers every day including underage girls from the families of Japanese who worked for the military and the Manchukuo rail at Beian airport and Japanese military nurses. The Russians seized Japanese civilian girls at Beian airport where there were a total of 1,000 Japanese civilians, repeatedly raping 10 girls each day as recalled by Yoshida Reiko and repeatedly raped 75 Japanese nurses at the Sunwu military hospital in Manchukuo during the occupation. The Russians rejected all the pleading by the Japanese officers to stop the rapes. The Japanese were told by the Russians that they had to give their women for rape as war spoils.
Soviet soldiers raped Japanese women from a group of Japanese families that were with Yamada Tami that attempted to flee their settlements in 14 August and go to Mudanjiang. Another group of Japanese women that were with Ikeda Hiroko that on 15 August tried to flee to Harbin but returned to their settlements were raped by Soviet soldiers.
