Size of Japan

It's about 144,000 square miles, or 372,000 square kilometers. That's about one twenty-fifth the size of the United States. Japan is an island nation. That figure covers the four main islands and roughly 3,000 smaller islands as well. The islands run in a general northeast to southwest direction. The length is about 1,860 miles, or 3,000 kilometers.

Less than twenty percent of their land can be used for agriculture. And about seventy-five percent of the total land area is mountainous. Most of the mountains are covered with forests.

There's not very much of residential land. Less than five percent of land area is suitable for residnetial use. That's one of the reasons that land is so expensive, especially in the cities.
