Model for the counterclockwise rotation of Northeast Japan associated with the Japan Sea opening

Northeast Japan rotated in the period between 21 and 18 Ma, during which a transverse fault (the Chokai-Ishinomaki Tectonic Line: CITL) occurred between the Kitakami and Abukuma Mountains. Dextral movement on the CITL accommodated the larger counterclockwise rotation of the Kitakami Mountains. (see Hoshi and Takahashi, this issue)
