In recent years, several observations based on direct current measurements and model simulations have been successful in detecting a north east ward under current, _ Ryukyu _ along the Pacific side of the Ryukyu Is lands with a unique _ north east ward current _ structure. The volume transport (20 - 25 Sv) of the Ryukyu current completes the volume transport budget (45 - 50 Sv) of the Kuroshio system. A Pacific Ocean circulation model based on the RIAM Ocean Model (RIAMOM) with _ resolution success fully reproduced the observed structures of the north east ward Ryukyu Current with a subsurface core at 500 - 600 m. A three-layer model simulation shows the existence of the Ryukyu Current and explains the mechanism of subsurface current maximum through blocking effect of bottom topography around the Ryukyu Islands
