What 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.

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.

The elimination of isolationist policies in Japan was caused by the need to raise money through tariffs on imports.
