Around 23 million years ago, western Japan was a coastal region of the Eurasia continent. The subducting plates, being deeper than the Eurasian plate, pulled parts of Japan which become modern Chūgoku region and Kyushu eastward, opening the Sea of Japan (simultaneously with the Sea of Okhotsk) around 15–20 million years ago, with likely freshwater lake state before the sea has rushed in.

During the late Neogene period (23.03-2.58 million years ago), the Japan Trench underwent a period of plate convergence between the Pacific and Okhotsk plates. Based on the sediment sequence during this time, there appears to have been little net accretion of sediment onto the overlying plate as well as evidence of mild erosion at the base of the convergent margin.
The west coast of Honshu, bordering the Sea of Japan, is a north–south trending convergent boundary. [2] This boundary between the Amurian and Okhotsk Plates is thought to be an incipient subduction zone, consisting of eastward-dipping thrust faults. [3] Convergent tectonics have been occurring in the region since the end of the Pliocene. [4]
Three types of plate boundary Convergent boundary Divergent boundary Transform boundary. Tectonic plate interactions are classified into three basic types: [1] Convergent boundaries are areas where plates move toward each other and collide. These are also known as compressional or destructive boundaries.
The margin is located at the boundary marking the Amurian and Okhotsk microplates. Oceanic lithosphere from the Sea of Japan located on the Amurian Plate converges with the Japanese archipelago on the Okhotsk Plate. A Wadati–Benioff zone which is evidence for subduction, is absent in the zone, hence subduction is doubtful.
Currently Japan is situated on the convergent boundaries between the Pacific, Philippine Sea, Okhotsk and Amurian Plates. Along the island arc's east and southeast coasts, subduction of the Pacific and Philippine Sea plates occurs at the Japan Trench and Nankai Trough, respectively.
In plate tectonics, the Nankai Trough marks a subduction zone that is caused by subduction of the Philippine Sea plate beneath Japan, part of the Eurasian plate (Kanda et al., 2004). This plate boundary would be an oceanic trench except for a high flux of sediments that fills the trench.
