In total 82 tropical cyclones data was used to determine scenarios of translation speed, minimum SLP and track. The numerical simulation of waves and flows was conducted by solving non-linear long wave equations. The maximum surge height shows that the typhoon passing through along north-east directional track is dangerous for Tokyo Bay. This trend confirms the previous risk assessment was reasonable. However, it has been shown that the typhoon passing through along north directional track is also dangerous although the frequency is low. Especially, it is interesting that the typhoon passing through along north-west directional track causes distinctive harbor oscillation.
