Which island nation has 3/4 of its land covered by mountains?

• A. Japan
• B. South Korea
• C. Taiwan
• D. Philippines

Answer: (A)

Japan is the island nation where approximately 75% of its land is covered by mountains. This mountainous terrain is a result of the country’s geological history, as it is situated in a tectonically active region known for volcanic activity and mountain-building processes. Major mountain ranges, such as the Japanese Alps and the Chugoku Mountains, dominate the landscape, influencing climate, agriculture, and urban development within the country.

The presence of these mountains has also shaped Japan's cultural and historical development, as many settlements have emerged in the valleys and along the coastal regions, often striving to adapt to the challenging mountainous terrain. Other countries listed, like South Korea and Taiwan, also have significant mountainous regions, but they do not reach the same level of coverage in terms of their total land area compared to Japan. The Philippines, while home to various mountain ranges and elevated regions, has a more diverse geography that includes extensive plains and numerous islands. Therefore, Japan stands out for its substantial mountainous coverage relative to its total landmass.
