With the use of the two-dimensional tidal model including the tide generating potential tend tidal charts of four major tidal constituents (M$_2$, S$_2$, $K_1$, $O_1$) are presented in the East Sea (Japan Sea). Model results showed that the inclusion of tide generating force does influence the position of semi-diwrual amphidrumes in the Korean east coast but computed results are generally in .good agreements with coastal observations and also empirically drawn existing charts of this region.
