Final answer:
Conflict arose after the Great Kanto Earthquake of 1923 with the targeting of Korean individuals, while cooperation was exemplified by the international aid response to the 2011 Tohoku earthquake and tsunami.
Step-by-step explanation:
The Tohoku Earthquake and Tsunami of 2011 provides a stark example of both conflict and cooperation in the face of a natural disaster. An example of conflict can be seen in the aftermath of the Great Kanto Earthquake in 1923, where rumors led to the targeting and killing of several thousand Koreans. However, an example of cooperation can be drawn from the global aid response to the 2011 disaster, where many countries, including the United States, provided substantial support to the affected Japanese regions, illustrating international solidarity during times of crisis.
