In this paper, we summarize our recent studies using the high-resolution <SUP>14</SUP>C dating analysis on Holocene wave-dominated coastal sequences in the Kujukuri and Sendai coastal plains, eastern Japan. Results of high-resolution <SUP>14</SUP>C dating, depositional facies, grain-size and depositional-depth analyses reconstruct temporal and spatial developments of the sequences in relation to the Holocene relative sea-level change and regional sediment supplies in detail. From the comparison between the sequences, we discuss (1) how the nature and developments of the sequences were affected by the differences in style and amount of sediment supply, (2) relationship between relative sea-level change and grain-size characteristics, and (3) controls on preservation potential of wave-dominated sequence.
