This is a Geosite with a beach of squeaking sand that is about 5 km in length from east to west. Since olden times, people have lived here utilizing the unique geological features formed by the development of the sand dunes.
（1）Hamamura Kaigan Coast
This is a sandy beach that stretches from the Tatsumidai Observatory to Nagaohana. In this area, “Kaigarabushi,” a song about fishing for scallops, has been handed down. There are sand dunes behind the beach.
（2）Uomidai Observation Deck
This is a height on the east side of the Nagaohana. Uomidai (meaning “height for watching fish”) was named because an old fisherman shouted when he found a great shoal of sardines approaching.
（3）Nikko Pond
This is a lagoon formed by the blocking of an inland bay by sand dunes. This area was reclaimed and developed into rice paddies by the feudal lord Kamei Korenori in the Sengoku Period. However, the lagoon appeared during winter. Even today, a lagoon appears in winter when the water is effluent, and many water birds gather at the lagoon.
（4）Kaigarabushi Festival
This summer festival is held on the theme of “Kaigarabushi,” a song handed down in Ketaka Town. On the first evening of the festival, on the Funaiso Coast, fireworks are sent up from the sea to the sound of the sea waves. On the second day, local people dance the Soodori dance singing Kaigarabushi.
