Miocene granitic rocks are exposed in the Goto Islands and Tsushima. Two bodies of granitic rocks with both normal and reversed NRM directions in the same mass were found in Hisaka-jima and Tsushima. Directions of the NRM of Goto and Tsushima granitic rocks are significantly consistent with each other, and it is concluded that the consistency in NRM directions demonstrates the contemporaneity of plutonic activity in both the regions. The VGP positions obtained from intermediate polarity directions were situated in the Southern Pacific Ocean without one site in the Goto Islands.
