Which explains the decline of Japan’s isolationism?

Limited natural resources on the islands of Japan led to the end of isolationism and allowed for the rise of Japanese industrialization.
The elimination of isolationist policies in Japan was caused by the need to raise money through tariffs on imports.
Fearing an invasion by Russia, Japanese leaders eliminated isolationism as a foreign policy so they could seek assistance from China.
Western cultures forced treaties on Japan that would open its ports and end its imposed trade limitations and isolationism.

D?

You are correct! :)

Yes, option D is the correct explanation for the decline of Japan's isolationism. Western cultures, particularly the United States, forced treaties on Japan in the mid-19th century that opened its ports and ended its imposed trade limitations and isolationism. This process is known as the "Opening of Japan" or the "Meiji Restoration." These treaties, such as the Treaty of Kanagawa in 1854, were a result of Western powers, led by the United States, exerting pressure on Japan to abandon its isolationist policies and open its ports to international trade. This marked a significant turning point in Japan's history and paved the way for its modernization and industrialization.
