japanese imperialism.
world war ii battles.
japanese industrialization.
world war i battles.

Explanation:

The map depicts Japan's territorial acquisitions (Manchuria, Korea, etc.) in the 1930s, which is a core example of Japanese imperial expansion. World War II battles occurred later (1939-1945) and focus on combat sites, not territorial takeover scope. Japanese industrialization is an economic process unrelated to territorial maps. World War I did not involve Japanese expansion in this region.

Answer:

Japanese imperialism.
