Summary Results are presented of the directions of magnetization for twentyeight sets of rocks collected from different parts of Japan. The directions for rocks of Pre‐Tertiary age from south‐west Japan differ systematically from those from north‐east Japan. It is suggested that the difference is due to the deformation of the Japanese Islands in the late Mesozoic or early Tertiary. Because of the deformation, it is not possible to infer the accurate position of the geomagnetic dipole with respect to Japan for Pre‐Tertiary times.
