Three radiocarbon ages were obtained for the molluscan shells collected from the Holocene marine deposits distributed in the Tanabu alluvial plain of the Shimokita Peninsula, Aomori Prefecture. The shells were contained in the silt bed distributed at the inner part of the restored embayment, at about 1.5 .times. 0.5 meter above mean sea level. The ages of the uppermost part of the silt beds are 5480 .+-. 120, 5920 .+-. 130 and 6370 .+-. 190 y. B. P. for sites 1, 3, 5 respectively. The results are consistent with the previous estimation that the marine beds in the Tanabu area were accumulated during the culmination stage of the Jomon Transgression.
