Abstract We conducted seafloor geological mapping using the submersible
“ SHINKAI 6500 ” along the Shionomisaki submarine canyon, off Kii peninsula,
Southwest Japan, in order to document the distribution of outcrop-scale structures
and strain in the accretionary complex of the Nankai trough. We investigated
outcrops in the seaward-most part (frontal thrust zone), the landward-most part
(megasplay fault zone) and an intermediate part (imbricate thrust zone) of the
