Japan is a country with a historical tradition of militarism.

The Japanese militarism has been plotting for a long time to launch a war of aggression against China.

After the unification of Japan, Toyotomi Xiuji proposed to attack and occupy North Korea, attack Beijing, occupy North China and seal the territory in the East Asian continent.

In 1868, Japan began the Meiji Restoration and gradually embarked on the road of modernization.

At the same time, it also began to form a mainland policy with China as the main expansion target.

In the more than 70 years since the Meiji Restoration, Japan has launched and participated in 14 wars of aggression against foreign countries, of which 10 were aggression against China.

After the Sino Japanese War and the two wars between Japan and Russia, the backward Japan not only squeezed into the ranks of the imperialist powers to carve up China, but also gained an advantageous position in Northeast China.

After the Russo Japanese War, Japan has developed into a Military Feudal imperialist country, and its desire to seize world hegemony by force has become stronger.

After the Eastern Conference convened by the cabinet of ichiichi Tanaka in 1927, Japan accelerated the pace of implementing the new continent policy in an attempt to first turn Northeast China into a colony under its direct rule.

The Japanese ruling group, especially the heads of the military headquarters and the Kwantung Army, began to formulate an action plan to occupy Northeast China while proclaiming that the “Manchu Mongolian lifeline” was facing a crisis.

As early as July 1929, Guan Er Ishihara, chief of staff of the operations department of the Kwantung Army, was ordered to draft a document entitled “the plan for the Kwantung Army to occupy Manchuria and Mongolia”, which put forward the specific idea of occupying Northeast China by force.

In order to fully verify its concept, reconnoiter the important military areas in Northeast China and improve the plan of occupying Northeast China, the Kanto army successively organized three large-scale “staff tours” from July 1929 to July 1931.

The first time was called “North Manchu staff travel”.

Under the command of sakigaki zhengsiro and Ishihara Guaner, senior staff officers of the Kwantung Army, they tried to study the problem of offensive and defensive operations near Harbin.

From July 3, 1929 to July 12.

The route starts from Lushun and passes through Changchun, Harbin, Qiqihar and Hailar to Manzhouli.

On the return trip, turn to taoang line via angxi, to Tailai and Taonan, and then return to Lushun.

On July 4, when Ishihara arrived in Changchun, he delivered a speech on the Grand View of war history.

On the train from Changchun to Harbin, he put forward “the fundamental national policy to reverse the national movement – the solution to the Manchu Mongolian problem” and “the plan for the Kwantung Army to occupy Manchuria and Mongolia”.

In the “solution to the Manchu Mongolian problem”, Ishihara systematically expounded the “Ishihara idea” of occupying “Manchu Mongolian” and transforming Japan’s national movement, and believed that the next World War was “the last war of mankind”.

The expansion of American power to the Far East will be the biggest challenger to hinder Japan’s development to the mainland.

In today’s world, with aircraft that can navigate the world and developed science and technology, “Japan in the center of Oriental civilization” and “the United States in the center of Western civilization” are bound to go to war.

In order to prepare for the war against the United States, “solving the Manchu Mongolian problem is the only way for Japan”.

He pointed out that Japan’s possession of “Manchuria and Mongolia” can not only restore domestic prosperity and eliminate unstable factors, but also “timely extinguish the flame of expelling the sun in eastern China”.

This is “the fundamental national policy for changing Japan’s National Games”.

As a premise, “the solution of the Manchu Mongolian problem can be fully realized only when Japan owns the place”.

In the “plan for the Kanto army to occupy Manchuria and Mongolia”, Shi Yuan proposed the following plan: the Kanto army occupied “Manchuria and Mongolia” and skillfully disarmed the Chinese army.

The Japanese “run large-scale enterprises” on this land, let the North Koreans “develop paddy fields” and the Chinese “engage in small business and manual labor”.

At the same time, four divisions were stationed in “Manchuria and Mongolia” to “prevent the invasion of the Soviet Union”.

The second was the “Nanman Liaoxi staff Tour” in October 1929.

Its purpose is to study the problem of fighting near Jinzhou.

After the research on “attack essentials of Fengtian city” and “night attack of Gongchangling” has been completed, they began to study the battle plan of crossing the river in Xinmintun, pursuing Jinzhou, and attacking Jinzhou and the west of Shanhaiguan.

In 1931, the Kwantung Army organized the third staff tour, still known as the “North Manchu staff Tour”.

The main reason why they are not familiar with the “northern staff” of the eastern army is that they are not personally familiar with the “northern staff” of the eastern army.

During this period, sakagaki and Ishihara commissioned Zuo Jiu and Jian Liangsan to draft the “study on the rule of Manchuria occupied areas” based on the “Ishihara concept”, which was also completed in September 1930 and officially printed by the Kwantung Army in December.

This document proposes that the purpose of occupying “Manchuria and Mongolia” is to “quickly occupy Manchuria and one part of Mongolia and completely place them under our power, so as to obtain resources for long-term foreign operations and other relevant solid bases.

” It also makes clear provisions on the administrative rule after Japan’s occupation of Northeast China in the future.

This shows that the Kwantung Army is not only actively planning to occupy the northeast, but also preparing for how to rule the occupied areas.

By March 1931, under the planning of banyuan, Ishihara and others, the command of the Kwantung Army officially formulated the “treatment plan for the Manchu Mongolian problem”, decided that “in case of extraordinary circumstances, the Kwantung Army should be determined to overthrow the government and occupy Manchuria and Mongolia by itself”, and envisaged the “strategy of creating events”.

At this time, at the top level of the Japanese military headquarters, the theory of “ensuring Manchuria and Mongolia First” began to rise.

In April 1931, the general staff of the Japanese army drew up the judgment of Showa VI (1931) annual situation, and discussed how to solve the “Manchuria” problem.

It is determined that there are three steps to solve the “Manchuria Mongolia” problem: the first step is to change the current situation in which Japan’s so-called “legitimate rights and interests” are damaged, so as to ensure and further expand this right and interest.

The second step is to form a new regime independent from the Chinese central government in “Manchuria and Mongolia”.

The third step is to completely occupy Northeast China.

According to this plan, on June 11, 1931, under the chairmanship of MEICI Jianchuan, director of operations of the General Staff Department, the “five section chiefs meeting” of the military, personnel, staffing, Europe, America and China sections of the army province and the army general staff was held to further agree on the action plan.

On June 19, the outline of strategies for solving the Manchuria problem was formulated, which stipulates that within the next year, we should thoroughly understand the actual situation of “Manchuria and Mongolia” and Japan’s position at home and abroad, and prepare for military action.

In July, Guangji Miyake, chief of staff of the Kanto army, went to Tokyo and issued the above outline as an instruction to the Kanto army.

At the same time, the Japanese Kwantung Army directed the “Wanbaoshan bloodshed”.

Wanbaoshan is 30 kilometers northeast of Changchun, Jilin ProvinceWithin three districts of Changchun county.

It is completely under the jurisdiction of the Chinese government.

It is neither a subsidiary of the Manchurian Railway nor a special zone stipulated in the Sino Japanese Tumen river boundary treaty signed in 1909.

In April 1931, at the instigation of the Japanese Consulate in Changchun, North Korean Li shengxun and others came to the place and privately rented 7500 mu of wasteland leased by Hao Yongde, manager of “Changnong rice field company”.

Without the approval of Changchun county government, the lease hired Koreans to dig canals without authorization, destroying the cultivated land of local farmers and causing disputes.

The Japanese Consulate in Changchun thought there was an opportunity, so it sent Japanese police to the construction site of Wanbaoshan to suppress the Chinese people.

In July, Japanese imperialist controlled newspapers distributed “extra” in North Korea, spreading rumors that North Koreans “killed hundreds” in Wanbaoshan and deliberately incited retaliation, resulting in a series of anti Chinese atrocities in some major cities in North Korea, but the Japanese governor’s office and local authorities deliberately ignored it.

The Japanese ruling group took the opportunity to vigorously incite the war.

At the civil affairs party conference held in Akita on July 9, Prime Minister ruohei Yiwei said: if China’s handling measures are illegal and inappropriate, in order to protect the survival of the country, we must not be afraid of any sacrifice and rise up bravely.

The people must not relax this preparation.

In the name of investigating the incident, the general secretary of the political friends association went to Northeast China in August.

After returning home, he instigated and said: “the situation in Manchuria and Mongolia is serious, and Japan’s right to survival is only tending to collapse day by day.

There is no other way to save this situation except to mobilize national strength.

” The “Wanbaoshan incident” was not settled.

On August 17, 1931, the Japanese army Ministry issued a communique, declaring that the Japanese staff and infantry captain Nakamura zhentaro and his party “traveled to Taonan”, were “illegally kidnapped and imprisoned” by China’s Xing’an reclamation army and were shot and killed.

The truth is: in June 1931, Nakamura zhentaro was ordered by the general staff to carry out a secret military reconnaissance mission in Northeast China.

Nakamura disguised as an “agronomist” and four veterans, including Inoue shanyantaro, were seized by the third regiment of the Northeast reclamation army in Yu Gongfu, Huai’an district on the way back through Taonan after conducting a military geographical survey of China’s Xing’an reclamation area.

Immediately, “two Japanese and Russian military maps, three diaries and three notes were found in the pants”, which recorded “the rainfall, climate, villages, residents, soil quality, water wells and the troops that can be accommodated in detail”.

At the same time, guns and other espionage equipment were also found.

Tunken army identified Nakamura as a military spy based on conclusive evidence.

Commander Guan Yuheng ordered the execution of four military spies.

Originally, it was beyond reproach for China to dispose of a well-documented spy in order to safeguard national sovereignty, but the Japanese authorities with ulterior motives took advantage of the issue, protesting to the Chinese government on the one hand and inciting the upsurge of Anti China war on the other.

The former commander of the Kwantung Army, Yoshizawa Shirakawa, and others proposed at the meeting of military councillors that “we should take advantage of the Nakamura incident to resort to force to solve all outstanding cases and ensure our rights and interests”.

Shiyuan Guaner, chief of staff of the operations department of the Kwantung Army, said: “the Nakamura incident is a heaven given opportunity to send troops to places outside the affiliated areas, and can even become a prerequisite for the exercise of force in liutiaogou.

” On August 24, the army province decided that “it is necessary to carry out protective occupation of Taonan area” when China denies the execution of Zhongcun or fails to get a satisfactory solution.
