In 1931 the Manchurian component of the Japanese Imperial Army faked the sabotage of the Southern Manchurian Railroad (which was controlled by the Japanese themselves) near Mukden (present day Shenyang). The Japanese military, playing the victim, alleged it was the work of Chinese dissidents, and used the so-called Mukden Incident to launch a full-scale invasion of Manchuria✴.

The military onslaught from Japan’s Kwantung Army (formerly Garrison) [関東軍, Kantogun] (AKA the Guandong Army) met with determined if largely ineffective resistance…the Chinese were under-prepared, under-equipped and not as technologically advanced militarily as the Japanese, but their defensive efforts were also undermined by Chinese leader Chiang Kai-shek who ordered the local warlord Zhang Xue-liang✪ to hold back on resisting the Japanese invaders. The reason – Chang had fixed on a strategy that prioritised gaining control over the rest of the China in the civil war against Mao’s Chinese communists [‘Mukden Incident’, Encyclopaedia Britannia, (John Swift), www.britannia.com]. The Japanese military successes were followed by the creation of a Japanese “puppet state”, Manchukuoꆤ, in Manchuria in April 1932 (comprising China’s Northeast and Inner Mongolia).
Background to Manchukuo: Japanese “special interests’
Japan had pursued an aggressively interventionist policy in the region for decades before Manchukuo. Victorious wars against a diminishing Chinese empire (First Sino-Japanese War, 1894-95) and Tsarist Russia (Russo-Japanese War 1904-05) emboldened Japan’s ambitions. Japan’s spoils of war after defeating the Russians included the extension of its economic sphere of influence to southern Manchuria. Moving into ports, mines, hotels and other businesses and its takeover of Russian railroads, brought with it a big influx of Japanese settlers [‘Manchukuo’, Wikipedia, https://en.m.wikipedia.org/].
Even prior to Manchukuo’s creation, Japan had been conceded a portion of Chinese territory in the southern Liaoning Peninsula which included Dalian (renamed Darien by the Japanese). Known as the Kwantung Leased Territory, it remained in Japanese hands until 1945.
Manchukuo’s capital was Hsinking [Xīnjīng: (literally ‘new capital’)] (today reverted to its original name, Chángchūn) in Jilin province. In 1945 at the end of WWII the capital was moved to nearby Tonghua. Hsinking had the status of a “special city” under the Manchurian state, as did Harbin.
Puppet statehood
The Manchukuo state established by the Japanese militarists was initially a republic but in 1934 it was changed to a one-party constitutional monarchy, the so-called Empire of (Greater) Manchuriaᴥ. The Japanese dredged up the former boy-emperor Pu Yi (last Chinese emperor of the Qing Dynasty) to be the titular figurehead of the ’empire’. Executive power of the Manchukuo government purportedly resided with the prime ministers (Zheng Xiaoxu 1932-35 and Zhang Jinghui 1935-45). The Manchukuo PM held authority under an authoritarian–personalist dictatorship, but this was more perception than substance as real power lay firmly with the Japanese☯️.

Kwantung Army, a rogue element
The Kwantung◘ Army, the arm of the Japanese Imperial Army in Manchuria, functioned as something of a rogue element, habitually acting independently of the Japanese government and the Army General Staff in Tokyo which struggled to rein it in. The Mukden Incident (see above) and the Huanggutun Incident (see below) are two such instances of their rogue activities. Service in the Kwantung Garrison, which had its headquarters in the Manchukuo capital Hsinkingᕡ, was a recognised path for promotion in the Japanese high command…instrumental chiefs of staff Seishirō Itagaki and Hideki Tōjō were both beneficiaries of this [ibid].
Hsinking: Kwantung Army HQs ⇓
Highly politicised, the Kwantung Army adopted an extra-military role for itself in Manchuria, eg, the commanding officer of the Kwantung Army was also Manchukuo ambassador to Japan and held an extraordinary power of veto – even over the Emperor of Japan! [ibid.].
‘Race’-based stratification
Japan peopled the sparsely populated parts of Manchuria with Japanese migrants who sat atop a social pyramid with other ethnic groups in the region stratified under the Japanese. Rationing of essential foodstuffs (including rice, wheat and sugar) was administered in accordance with this racial hierarchy. The Japanese-dominated colony of more than 30 million has been characterised as more “an Auschwitz state or a concentration-camp state” than merely a “puppet state” [Yamamuro Shin’ichi, quoted in Smith, Norman. “Disguising Resistance in Manchukuo: Feminism as Anti-Colonialism in the Collected Works of Zhu Ti.” The International History Review, vol. 28, no. 3, 2006, pp. 515–536. JSTOR, www.jstor.org/stable/40111222].
Japanese dominated Manchuria was indeed a police state, one of the most brutal in an (interwar) era of totalitarian excesses. The Manchukuo regime unleashed a systematic campaign of terror and intimidation against the local Russian and Chinese populations (including arrests without trial, “thought crimes”, organised riots and other forms of subjugation) [‘Manchuria’, Wikipedia, http://en.m.wikipedia.org].

Resistance to Japanese domination
After the establishment of Manchukuo and the ineffective performance of the Fengtian (Liaoning) Army against the Japanese war machine, various Chinese militias were formed to carry on the resistance. The main forces comprised Anti-Japanese Volunteer Armies, backed by the KMT Nationalists and led by famous general Ma Zhanshanᕤ. Other resistance to the Japanese in the Northeast came from Communist-organised guerrilla units. The anti-Japanese militias’ campaigns, which included harrying and terrorising the Kwantung Army, lasted ten years until the Japanese Army and Airforce finally pacified Manchuria in 1942.
The brunt of the early Chinese fight-back against Japan’s imperial expansion was borne by these warlord militias and volunteer armies, but after Chiang Kai-shek was talked round to a truce with the communists and a united front against Japan in 1937 (in effect postponing the civil war to the conclusion of WWII), the Republic of China (ROC) army engaged directly with the Kwantung Army (Battles of Shanhai Pass, Rehe, Beiping-Tianjin, 2nd Battle of Héběi, Chahar Campaign, etc).

1937: Second Sino-Japanese War
After colonising Manchuria, the Japanese military used it as a base to invade the rest of China. In 1937 the eruption of fighting between Chinese and Japanese troops near Peking (Marco Polo Bridge Incident) led to full-scale war. Antony Beevor [The Second World War, (2012)] marks this episode as being effectively the start of the Second World War (some historians date it’s origins earlier, from the Mukden Incident in 1931).

Siberian sideshow
Eventually the Kwantung Army, unchecked by Tokyo, overreached itself by invading Siberia, provoking the USSR into an undeclared war and several border conflicts and battles in the late 1930s. The clashes culminated in the decimation of Japanese 6th Army at the Battle of Khalkhin Gol in August 1939 [‘The Forgotten Soviet-Japanese War of 1939’, The Diplomat, (Stuart D Coleman), 28-Aug-2012, www.thediplomat.com].
1930s Tokyo ‘spin’
The Japanese came under attack in the West for establishing a harsh, totalitarian regime in Manchuria. Attempts were made to deflect the criticism by portraying the interventions in China’s northeast as a positive contribution to the restoration of regional order. Apologists for Japan, pointing to the pattern of internecine conflicts between warlords, communist insurgency and general chaotic conditions in the rest of China in the first third of the 20th century, argued that Manchuria in the same period had, courtesy of Japanese involvement, enjoyed “peace and order, progress and prosperity, (making) great strides in commercial and industrial development” [Saito, Hirosi. “A Japanese View of the Manchurian Situation.” The Annals of the American Academy of Political and Social Science 165 (1933): 159-66. http://www.jstor.org/stable/1018175].

Japanese spin imbued the Manchukuo regime with a pseudo-legitimacy that was almost mythic: “the ‘Manchus’ followed the ‘kingly way’ (王道 wangdao) of harmony, prosperity, and peace under the benevolent guidance and protection of imperial Japan” [Review of Sovereignty and Authenticity: Manchukuo and the East Asian Modern, (Prasenjit Duara), by John J.

Myth-busting Manchukuo
Reconnecting with this, Japanese historians in the postwar period, tried to justify the horrors committed by the occupying Japanese army, characterising the incursion in Manchuria and Inner Mongolia as an act of ‘liberation’, prompted by motives which were ‘enlightened’. Recent research by Shin’ichi Yamamuro leads the Japanese academic to posit a view of the Manchukuo occupation that challenges the mainstream Japanese one. Yamamuro debunks the theory that right-wing Japanese military and civilian authorities were supposedly imbued with the idealism of wanting to construct a “paradise in earth” in China’s three northern provinces [Manchuria Under Japanese Dominion, (Shin’ichi Yamamuro, translated by Joshua A. Fogel), 2006; Bill Sewell. “Review of Yamamuro Shin’ichi. Manchuria under Japanese Dominion. Translated by Joshua A. Fogel.

“Greater Co-operation” – code for Japanese expansion and economic domination
In 1940 Japan incorporated its Manchurian client-state into the Greater East Asia Co-Prosperity Sphere (GEACS). The purported aim of GEACS was that it would be an economically self-sufficient “bloc of Asian nations led by Japan and free of Western powers”. In reality, this veneer of Pan-Asian idealism (regime motto: “five races under one union”) was a front for the Japanese militarists and nationalists to expand south and west and advance its domination of Asia [‘Manchukuo’, Wiki, loc.cit.].
A prized economic asset
Manchukuo (and the Inner Mongolia territory) was incorporated into both the Japanese war machine and the national economy. Rich in natural resources (especially coal and iron), under the Japanese Manchuria became an industrial powerhouse. Japanese citizens, who had been hard hit by the Great Depression, were enthusiastic in their support for the army’s intervention in Manchurian territory right through the period of Japanese occupancy [ibid.].
August 1945: D-day for the Japanese puppet states
August 9, 1945, the day after the second atomic bomb was dropped on Japan, the Soviet Red Army and the Mongolian Army invaded Manchuria and Inner Mongolia, which was to be the final campaign of the Second World War. In a swift operation (Manchzhurskaya Strategicheskaya Nastupatelnaya Operatsiya), Manchukuo, Mengjiang and Japanese (northern) Korea were all liberated, thus culminating in the break-up of the Japanese empire. Manchuria and Inner Mongolia were returned to China, and the Soviets set about orchestrating a communist takeover of North Korea…meanwhile Korea south of the 38th Parallel was occupied by US forces [‘Soviet invasion of Manchuria’, Wikipedia, http://en.m.wikipedia.org].

Footnote: ‘Manchuria’ as a geographic descriptor was first used by the Japanese in the 1600s and later adopted by Westerners in China…the Chinese themselves these days are less inclined to use the term ‘Manchuria’, preferring to describe this part of China simply as Dongbei (东北), the Northeast).
Manchurian malfeasance – for the record: these days the once imperial “puppet palace” of Manchukuo is a history museum – a reminder to Chinese and the very occasional 外国人 (foreign) visitor alike of the aberrant and abhorrent regime imposed on North-East China during the interwar period of the 20th century.

✴ in 1932 an independent inquiry with US participation, the Lytton Commission (Ritton Hōkokusho), found that both parties were at fault for the incident. In its Report which led to exposure of the Japanese duplicity, it condemned Japan for its aggression (albeit conceding it had “special interests” in the region), while also criticising China for inflaming anti-Japanese sentiments…the League of Nations subsequently demanded that Japan vacate Manchuria, Japan’s response was to give notice to withdraw unilaterally from the League (effective 1935) [‘Lytton Report’, (United States History), www.u-s-history.com]
✪ Zhang’s father, Marshal Zhang Zuolin, also a Manchurian warlord, had been assassinated by the Japanese Kwantung military in 1928, in an episode in Shenyang known as the Huanggutun incident. Zhang senior was one of the most powerful warlords in the Warlord Era, which saw local military cliques carve out territorial strongholds in different parts of China

His successor Zhang Jinghui was even more of a powerless figurehead, content to allow advisors from the Kwantung Army run the state, earning Zhang the unflattering sobriquet of the “Tofu prime minister” [‘Zhang Jinghui’, Wikipedia, http://en.m.wikipedia.org]
