Summary:Current knowledge of the geology of SW Japan is reviewed and earlier syntheses of its tectonic evolution are reassessed; none account adequately for all the data. A new synthesis is proposed in which allochthonous terrains, originating within the Pacific Basin, have been moved northwards throughout the Mesozoic and Tertiary by the movement of the Pacific plates and accreted to the margins of Asia. Subsequently, accreted terrains have been driven northwards along sinistral transcurrent faults, perhaps for thousands of km, by oblique subduction. The tectonic units which constitute SW Japan represent an accumulation of disparate allochthonous terrains, not necessarily related either in origin or early history, brought together by movement along major transcurrent fault zones.
