Recently, the wave hindcasting models have been very much improved as seen in the successful development of the third generation wave model such as the WAM. In addition, accurate and reliable meteorological data for several decades has been supplied from the international organizations such as the ECMWF (European Centre for Medium-Range Weather Forecasts) and the NCEP (The National Centers for Environmental Prediction). Thus it is getting easier to simulate ocean waves with these wave models and meteorological data for the past of tens of years. Now the accurate and reliable wave information can be obtained for long term in various ocean areas.
　On the other hand, however, the introduction of the third generation wave models to simulate the costal waves is still under development although most of the coastal engineering projects necessitate estimating wave information around the costal areas. One of the reasons of this delay is the difficulty of estimating accurate wind field around the costal area surrounded by the lands, where the wind field is sometimes very complicated. Accurate wind simulation with high spatial resolution is strongly required for accurate estimation of the waves around the coastal area.
　We, therefore, applied the mesoscale meteorological models such as the ANEMOS (Nakanishi, 1999) for wind simulation around the Tokyo Bay area. Then, we simulated coastal waves around the area with the third generation wave models, WAM and SWAN, with the wind data simulated by the mesoscale meteological model.
　In this paper, we examined the accuracy of the simulated wind field as well as the wave field around the Tokyo-Bay area by comparing the measured wind data and wave data, and discussed the applicability of the mesosocale meteological models as well as the third generation wave models with introducing some information for improving the estimation accuracy of the WAM.
