"Contrary to urban legend, the Hilo breakwater was built to dissipate general wave energy and reduce wave action in the protected bay, providing calm water within the bay and protection for mooring and operating in the bay; it was not built as a tsunami protection barrier for Hilo.
In fact, in 1946, Hilo was struck by a tsunami generated by an earthquake in the Aleutian Islands; it was struck again in 1960 by a tsunami generated by the great Chilean earthquake - both tsunami overtopped the breakwater and Hilo sustained significant damage, including to the breakwater."

There is a difference between a breakwater and a sea wall from an engineering standpoint.
