For safe navigation, high-resolution information on tidal current, wind and waves is very im-portant. In coastal areas in particular, the weather and ocean situation change dramatically in time and place according to the effects of geography and water depth. In this paper, high-resolution wave data was generated using SWAN as a numerical wave model. To estimate waves, wind data is necessary. By using the mesoscale meteorological model of WRF-ARW, detailed wind data was generated. The tidal current data was generated by using POM. We simulated tidal currents, wind and ocean waves for the duration of a typhoon passing over Japan in Sep-tember of 2004. Secondly, we simulated ship maneuvering using simulated tidal current, wind and wave data. For the ship maneuvering model, the MMG (Mathematic Modeling Group) was used. Combining high-resolution tidal current, wind and wave data with the numerical navigation model, we studied the effects of tidal current, wind and waves on a ship’s maneuvering. Comparing the simulated route lines of a ship with the set course, it was recognized that the effects of the tidal current, wind and waves on a moving ship were significant.
