The relationships between the dominant phytoplankton and the water quality factors were examined at two stations in the inner part of Tokyo Bay.<br>Monthly changes of water quality factors in the inner part of Tokyo Bay showed that DIN (dissolved inorganic nitrogen): DIP (dissolved inorganic phosphorus) ratio was high in February and March and low in October and November, while TN (total nitrogen): DIN ratio was low in January and February and high in August and September.<br>The relationships between the dominant phytoplankton and the water quality factors were considerably variable and complex. <i>Skeletonema costatum, Heterocapsa triquetra, Eucampia zodiacus, Chaetoceros didymum</i>, and <i>Chaetoceros radicans</i> occurred in waters with comparatively high DIN:DIP ratio (>80), <i>Ceratium fusus, Ceratium lineatum, Rhizosolenia fragilissima</i>, and <i>Leptocylindrus danicus</i> did in waters with moderate DIN:DIP ratio, and <i>Heterosigma akashiwo, Prorocentrum minimum, Gonyaulax verior</i>, and <i>Chaetoceros debile</i> did in waters with comparatively low DIN:DIP ratio (<50). DIN:DIP ratio in waters where dominant phytoplankton occurred tended to decrease with increased TN×TP and WT.
