The trend of the pre-Miocene structures of Japan is bent in Kyushu and central Japan. On-land geologic features such as the trend of synmetamorphic Jurassic lineations, Neocomian basins, and Late Cretaceous strike-slip faults have distorted trends as a result of the Miocene opening of the Sea of Japan. Accentuation of the bending in central Japan could be due to the Pliocene-Quaternary collision of Japan with the Izu ridge. A preopening reconstruction of Japan is proposed. The bent structural trends of Kyushu and central Japan, along with Neogene fault motions, are explained by a two-dimensional model of broad-scale, flexural-slip folding.
