What does it mean that the Japanese came to China to reclaim land during the war?

This is Japan's basic national policy.

From the July 7th Incident to Japan's defeat and surrender, it is the last stage and the most rampant stage of Japan's immigration policy to Northeast China, that is, the "national policy immigration stage". 1in April, 936, the kwantung army held the "second immigration conference" attended by kwantung army, military province, extension province, puppet Manchukuo government, Manchu colonial commune, Manchuria Railway, Japan Rural Rehabilitation Association and Manchu Immigration Association. In May, the meeting adopted the relocation plan of millions of agricultural immigrants in Manchuria and its specific implementation plan "Key Points for the Implementation of Temporary Class A Immigrants". On this basis, the Japanese Ministry of Foreign Affairs made a policy proposal and sent it to the Overseas Colonial Committee for approval in July. On August 25th, Hirota Hiroshi's Cabinet officially listed the "Twenty-year Plan for Immigrating Millions of Households" as one of the seven "national policies" of the Japanese government. Subsequently, the puppet government was asked to list it as one of the three "national policies". In order to hide people's eyes and ears, Japan renamed the "immigrant group" as "pioneering group" and the "immigrant cause" as "pioneering cause".

1In August, 937, the Kwantung Army reorganized and expanded "Manchuria Colonial Company" as the administrative organ of Japanese immigration activities in northeast China. At the same time, a "Colonial Committee" composed of senior officers of the Kwantung Army and ministers of the Puppet Manchukuo was established as the highest organ leading the migration activities of the Puppet Manchukuo. From 1939 to 12, Japan formulated the Basic Outline of Manchuria Development Policy, which was regarded by Japanese colonialists as the "highest aggregate" of their immigrant aggression. 1940, 194 1 year, Japan promulgated the pioneering group law, the pioneering cooperative combination law, the pioneering farm law, and implemented the immigration policy of one million households. Collectively referred to as "three development methods"

In order to really occupy China, the Japanese not only sent troops to China, but also sent a large number of immigrants to China. According to incomplete statistics, during the Japanese occupation of Northeast China, * * * sent more than 860 "pioneering groups" with more than 330,000 people. The "Pioneering Group" seized or forcibly bought the land of China people at a very low price, and then rented it to farmers in China for farming, thus making 5 million farmers in China lose their land, move around or starve to death in more than 2,000 "group tribes" formed in Japan, during which countless people froze to death and starved to death.
