a Map49 showing sampling locations (red triangles) and other intraplate volcanos (blue triangles). The grey triangles show the distribution of Holocene arc volcanoes. The white dashed lines show the depth contours of the Wadati–Benioff deep seismic zone in the subducting Pacific slab. The white solid line with small triangles is the location of the current Japan trench, and the large white arrow represents the subduction direction of the Pacific plate. b Horizontal slice of a 3D low-resistivity anomaly49, with the contours labeled with numbers are estimated water content (in ppm) in the asthenosphere based on existing resistivity and geotherm, and c vertical cross-section of S-wave velocity tomography97. The locations of the horizontal slice and the vertical cross-section are shown in (a) by the black dashed lines A-A’ and B-B’, respectively.
