three-dimensional geological model of the Japanese islands

The 3D geological model in the center of the exhibit room is that of the Japanese islands which has been scaled down to 1/340000th of its original size, and whose terrain has been exaggerated to 3 times its original height. You can hear the explanations concerning the geological characteristics of each regional area and the main techtonic lines by pressing the buttons on the panel. The Itoigawa-Shizuoka Tectonic Line, which bisects Japan from east to west, and the Median Tectonic Line, which similarly bisects southwestern Japan from north to south, are clearly marked. Compare the variation? in topography of places where old rocks and sediments? are, and where younger sediments have spread by referring to the legend; a color chart showing the topography according to type and geological age.
