b. has few natural resources.

Explanation:

Japan is one of the largest economies in the world, and even though it is a country with few natural resources, it managed to reach this level because it is a country whose main economic activities are focused on exports, according to production based on the Toyotist system, which is a on-demand manufacturing system, which reduces waste throughout the production process, which guarantees significant advantages. There is also a culture based on quality, innovation, education and technological development.

Japan's high population density constitutes a high human capital for work, which justifies the greater commercialization of goods and services. All of these factors justify how Japan became the world's third largest economy.
