Mikata Five Lakes , also called the Five Lakes of Mikata, are a series of brackish and freshwater lakes located in Mihama and Wakasa, Fukui, Japan, which are close to the coast of Wakasa Bay. They consist of Lakes Mikata (三方湖), Suigetsu (水月湖), Suga (菅湖), Kugushi (久々子湖) and Hiruga (日向湖). These five lakes are all located in Wakasa Wan Quasi-National Park. In 2005 the lakes were designated as a Ramsar site. The Lake Suigetsu is famous for its varves, which were adopted as a global standard for dating geological and historical relics in 2012.
