What are two ways that Japan’s environment allowed the civilization to be successful?

1. Geographic isolation: Japan's geographic isolation as an island nation allowed it to develop its own unique culture, which contributed to the formation of a strong national identity and a sense of unity among its people. This sense of unity helped in creating a stable society and government, which in turn facilitated the growth of the civilization.

2. Natural resources: Japan's environment provided abundant natural resources such as fish, rice, and timber, which sustained its population and supported economic development. These resources also allowed for the development of trade with neighboring countries, leading to cultural exchange and the acquisition of new technologies and ideas that ultimately contributed to the success of Japanese civilization.
