The Wave country is a small island nation which was once under the harsh rule of the shipping baron Gatô. Located off the coast of the Fire Country, the islands became impoverished because of the strong grip Gatô had over the shipping and transportation in the region. He ruled through fear, and anyone who dared stand in his way he had murdered as a warning. When Gatô was finally killed, Tazuna the bridge builder was able to finish his bridge and connect the country to the mainland. Thus the bridge allowed the country to become prosperous once again.
