Map showing the tectonic setting of the Japanese islands (a) and the geology of the study area (b) (National Institute of Advanced Industrial Science and Technology 2020b). a Thick black lines represent plate boundaries and black arrows represent relative plate motions (after Wei and Seno 1998). The blue rectangle represents the study area and the green shaded area is the eastern margin of the Japan Sea (see main text for discussion)
