Geography of Japan
The Japanese islands are the summits of mountain ridges uplifted near the outer edge of the continental shelf. About 73 percent of Japan's area is mountainous, and scattered plains and intermontane basins (in which the population is concentrated) cover only about 27 percent. A long chain of mountains runs down the middle of the archipelago, dividing it into two halves, the "face", fronting on the Pacific Ocean, and the "back", toward the Sea of Japan. On the Pacific side are steep mountains 1,500 to 3,000 meters high, with deep valleys and gorges.
