The formation of the Sea of Japan is closely linked to the evolution process of the Japanese Islands. Investigating lithospheric structure beneath the Sea of Japan would advance our understanding of the evolution history.
The lithosphere-asthenosphere boundary provides us with the first-order feature of the oceanic plate; that is, the plate thicnkess. We aim to detect converted seismic phases from the boundary and exploit the phase to constrain the lithophseric structure beneath the Sea of Japan.
