Japan, with limited resources and economic problems, needed resources beyond its borders and took over Manchuria in northern China.

Judge against the historical record as of 2018-11-11. The claim has three parts: Japan had limited natural resources, it faced economic problems (e.g., the Great Depression and the agricultural and export slump of around 1929-31), and it took over Manchuria in northern China. True: mainstream historical sources confirm that Japan occupied Manchuria (the Mukden Incident of 1931 and the creation of Manchukuo in 1932), and that its need for raw materials and resources beyond its home islands, together with economic distress, was a significant motive. Mostly true: the seizure and the resource motive are confirmed, but a secondary detail is off, such as the economic problems being framed loosely or the timing being imprecise. Mixed: Japan did take Manchuria, but historians treat resource need and economic trouble as a minor motive next to others (strategic or military-faction motives), so only about half the causal account holds. Mostly false: the takeover happened but the explanation substantially distorts the motives. False: Japan did not take over Manchuria, or the record shows the resource and economic rationale had no part in it.

   “Japan joined the allies against Germany in 1914-18 in a struggle to control a portion of China and then conquered Manchuria in 1931 in an effort to secure a land area rich in raw materials.”

   “Three factors creating this deadlock loomed large - the shortage of raw materials in Japan, the rapidly expanding Japanese population, and the division of the world into economic blocs.”

   “The conquest of Manchuria, a land rich in natural resources, was widely seen as an economic "lifeline" to save Japan from the effects of the Great Depression, generating much public support.”

   “While it seems that economic factors were important in Japanese expansion in East Asia, it would be too much to say that colonialism, trade protection, and the American embargo compelled Japan to take this course. Domestic politics, ideology and racism also played a role.”

E1 says Japan conquered Manchuria in 1931 to secure a land rich in raw materials. E2 names Japan's shortage of raw materials, alongside population growth and the division of the world into economic blocs, as a factor creating an economic deadlock [E2]. E3 says the conquest was widely seen as an economic "lifeline" against the effects of the Great Depression. E4 adds that domestic politics and ideology also played a role, but it calls economic factors important, so the resource and economic motive counts as significant, which meets the criteria for true.
