Countermeasure against tsunami in ports has not been taken sufficiently because of giving construction facilities for loading priority, even though ports could be damaged seriously by tsunami. The occurrences of gigantic earthquakes that cause huge tsunami are anticipated in Japanese coastal regions, so tsunami countermeasures in ports have to be one of important matters in the future.
In this paper, tsunami disasters in ports are studied by experiences in past, and countermeasures against them are proposed. Real-time tsunami observation offshore by GPS tsunami observation system, construction of breakwaters against tsunami and so on could be proposed as new program for tsunami countermeasures in ports.
