PROBLEM TO BE SOLVED: To provide a breakwater for tsunami enabling cost and time for construction to be saved and less constrained with respect to site location, a breakwater for tsunami for which an existing bank can be utilized, a breakwater for tsunami increased in capacity for preventing tsunami hazard with less cost and time by improving an existing breakwater for tsunami, and a breakwater for tsunami capable of suppressing adverse effects on scenery and living environments for living beings and having excellent economic efficiency. SOLUTION: A bag 2 having one or a plurality of gas chambers 1 is formed of a flexible membrane having water resistance and non-gas permeable or less-gas permeable property, and the lower part 3 of the bag is fixed onto a land. The bag having the gas chambers forms a bank body. Also, when the bag is covered with a strong skin and the lower part of the skin is fixed onto the land, the breakwater for tsunami of such a type that is exclusively installed on land in which the bag covered with the skin forms a bank body can be formed. The method of constructing the breakwater for tsunami uses the breakwater. COPYRIGHT: (C)2005,JPO&NCIPI
