This research investigates the protection performance against tsunami with the buoyancy- driven vertical breakwater by using the numerical simulations. Macro-Micro scale interlocked tsunami simulator named STOC (Storm surge and Tsunami simulator in Oceans and Coastal areas) has been applied to the series of simulations. Results of comparison of tsunami height in the Wakayama-shimotsu port and Fukura port due to Tokai, Tonankai and Nankai earthquakes indicates that this new breakwater decreases tsunami height and inundation area. Although the dissipating rate is depending on the position of this breakwater, the breakwater with 10% opening brings a 33% decrease in the maximum tsunami height.
