    This study investigated the influences of tides on a giant tsunami generated by the greatest earthquake scenario along the Nankai Trough occurring in the near future by conducting a tide-tsunami simulation in Osaka Bay as a pilot shallow ocean. Our results demonstrate that the tide-tsunami interaction is significant in the strong flood and ebb tide due to tidal advection. The speed of the tsunami intruding into the bay is enhanced (declined) by the advection of the flood (ebb) tide, leading to the early (late) approach of the tsunami wave to the coasts. More realistic tide-tsunami coupled simulation is essential to establish more effective hazard maps and evacuation scenarios.
