In order to find the variation of the Kuroshio transport in the East China Sea from the oceanographic elements, such as temperature or salinity, the relations between the total transport and temperatures or salinities of the different water masses constructing the Kuroshio are discussed, based on the geostrophic transport of the Kuroshio divided by every 1°C in temperature and 0.1‰ in salinity on the T-S diagram. The materials used in this study are the CSK oceanographic data along 125°E occupied by the Keiten Maru and the Kagoshima Maru in April and August of 1965 to 1970. The ratio of the partial transport of the subsurface water (thermosteric anomaly 440 cl/t-240 cl/t) to the total one is about 40% both in April and August. An instructive relation is found between the total transport of the Kuroshio (Tt km^3h^{-1}) and the salinity in the center of the subsurface water (S‰) : Tt=210(S-34.5)+35, where the value of 34.5 is adopted for the standard value of salinity. This fact suggests a possibility of finding the variation of the Kuroshio transport.
