The study is motivated by new findings on oceanography of the Japan Sea and by research on climate change in the adjacent area. The primitive equation quasi-isopycnal model (MHI model) is applied to simulate principal circulation patterns in the Japan Sea for two different climatic conditions observed in the mid and late 20th century. It is shown that redistribution of the Tsushima Current transport between western and eastern branches and development of the subarctic gyre in the northwestern Japan Sea are controlled by variation of vertical density stratification and baroclinicity in the sea, in accordance with climate change in the East Asia-Northwest Pacific marginal area.
