Research Abstract	In order to reveal characteristics of a bottom cold layer developing in coastal waters of Japan Sea, observations and data analyses were conducted. The result of the observations which conducted in Wakasa Bay showed that cold water intruded intermittently in the bottom layer during the stratification period. The results of the data analyses with historical data collecting in coastal waters of Japan Sea indicated that the bottom cold layer developed from the shelf slope region to the inner part of the Wakasa Bay in many years, and it revealed that the bottom cold layer affected the stratification process in water temperature and environment in fishing grounds.
