Synthetic analyses on typical element ratio and source discrimination function were carried out for a sediment core with high sedimentary rate collected along the Tsushima Warm Current (TWC) main stream on the southwestern slope of Japan Sea, in order to trace the sediment provenance change of the study area in the Holocene. Data suggest that the Nakdong River of Korea and Yangtze River of China are the main source of the studied sediments. Affected by the TWC strength evolution and sea level rise, their contributions changed with time. There are five stages. Their contribution became lower during 6.5~3.0 ka B.P. and 2.0~0.7 ka B.P.,  corresponding to the temporally weakening of TWC in the northern East China Sea and southwestern Japan Sea. In 3.0~2.0 ka B.P. and 0.7~0 ka B.P.,  TWC was strengthened and more fluvial materials from the Nakdong River and Yangtze River were deposited in the study area.
