Short summary
Analysing increased 137Cs and 134Cs / 137Cs ratio derived from the Fukushima Nuclear Power Plant accident in the Sea of Japan and its marginal sea, we found a rapid transport process associated with subduction in the subtropical mode water (STMW) formation region and obduction in the north East China Sea. The integrated amount of FNPP1 137Cs entering the Sea of Japan until 2016 was estimated to be 0.21 ± 0.03 PBq, which corresponds to 5.1 (3.4–8.0) % of the total amount of FNPP1 137Cs in the STMW.
