AbstractTrajectories of Argo floats deployed in the East/Japan Sea from 2001 to 2014 reveal that the middepth gyral circulation pattern of the Japan basin, the central part of the East/Japan Sea, undergoes a seasonal variation. The middepth circulation of the Japan basin is found to be characterized usually by the gyres trapped to the east of the Bogorov Rise (E-gyres) and those extending farther westward into the whole basin (BW-gyres). The E-gyre trajectories are generally associated with the turning of the floats toward deeper regions off the isobaths. This occurs in winter either on the northern or eastern side of the eastern Japan basin. It seems that the upstream part of the otherwise BW-gyre is subject to a strong negative wind stress curl in winter, and there the circulating water columns are driven toward the deeper region, thus triggering the formation of the E-gyre. The topographic effect associated with the Bogorov Rise seems to interfere thereafter in the process of determining the passage of the E-gyre. Otherwise, the water columns continue to flow along the isobaths, hence maintaining the BW-gyre. To the knowledge of the authors, this is the first observational evidence of seasonal variability in the middepth gyral circulation pattern in the East/Japan Sea. It suggests that oceanic middepth circulation, usually known to be quasi steady or slowly varying on climatological time scales, might also undergo a significant seasonal variation as it does in the East/Japan Sea.

The Japan Sea

It is reasonable to assume that Kaga han, in view of its size, large rice and other exports, and central coastal location, provided the lion's share of ships and shipowners operating in the Japan Sea during the two centuries before Perry. Villagers were going from Noto to North Honshu and Hokkaido both for temporary occupation and for permanent residence in the mid-seventeenth century and diereafter; and some of these emigrants became useful Kaga han trade agents. Moreover, transport of rice and salt respectively to Tsuruga and Echigo from Noto villages early in the Tokugawa period can be documented. Kaga han needed an all-water route to Osaka because of the high cost of transshipping rice by land from Tsuruga to Osaka. This may have been the main reason for the development in the latter part of the seventeenth century of nishi mawari, the route for ships going from the Japan Sea through the Inland Sea.
