本文连续给出了日本晚新生代构造图，显示了中新世以来的垂直位移量、褶皱轴走向和沉积岩变形程度。它们说明了东日本和西日本弧系之间的一些差异。在东日本弧系中，中新世初开始了一系列造山事件。晚新生代造山带与中生代造山带的走向不一致。虽然在北海道中部和大窝沟南部，古老的构造对年轻的造山带产生了一定的影响，但年轻的造山带似乎在遗传上独立于古老的造山带。东日本弧系由内火山带、外地背斜带和最外沉降海沟带组成。内带和海沟带构成一对高温构造带和低温构造带。这一对可能对应于环太平洋变质相研究所揭示的中生代造山带。
Late Cenozoic tectonic maps are serially given to show the amount of vertical displacement since Miocene, trends of fold axes and degree of de-formation of sedimentary rocks in Japan. They illustrate some differences between the east Japan and west Japan arc systems. Lines of evidence show that the former is more active.In the east Japan arc system a series of orogenic events started at the beginning of the Miocene. The trend of the Late Cenozoic orogenic belt is discordant with those of Mesozoic orogenic belts. The younger orogeny seems to be genetically independent of the older ones, although the older structures have given some effects on the younger ones in central Hokkaido and in south Fossa Magna. The east Japan arc system consists of the inner volcanic, outer geanticlinal and outermost subsiding trench belts. The inner and trench belts are regarded as forming a pair of high-temperature and low-temperature tectogenic belts. This pair may correspond to that of the Mesozoic orogenic belts as revealed by the study of metamorphic facies around the Pacific.
