10. Why did Japan decide to conquer other nations in Asia and the Pacific?

Many factors, economic, nationalist and domestic contributed to the expansion.

Explanation:

There were many materials that were important for Japan that were not available in Japanese sphere of influence.

Oil and rubber had to be traded from British Malaya and other neighboring countries controlled by European powers trying to limit Japan's expansion on the world stage.

Increasing nationalist sentiment and racism pushed the country into conquering its neighbors for pride and profits and to expand its sphere of influence.

Japan decided to conquer other nations in Asia and Pacific for its natural resources

Explanation:

Japan tried to seize other nations in order to use its natural resources to improve the Japanese administration and soldiery. Areas such as Manchuria were abundant in oil and metal deposits, which the island of Japan was severely lacking.

The antagonistic nature of the government also led to a rise in patriotism and the belief that Japan should be the legal owners of foreign colonies within Asia which also improved their desire for seizing other countries.
