KOSAKA Wado has given a list of fifteen prominent pyramid mountains of Japan. There are many others as an Internet search in Japanese will show. Pyramid mountains are man-made pyramids. Japanese made pyramids have a conical shape with a circular base. They are constructed out of natural mountains or built in layers of stone. Covered with soil, they have come to appear like natural forests over time.
