The sand at Ariake-hama is unique because it produces a distinct 'squeaking' sound underfoot, a phenomenon dependent on the high quartz content and lack of impurities.
The beach is located exactly at the base of Kotohiki Park, where the massive 'Zenigata Sunae'—a 122-meter wide sand sculpture of an Edo-period coin—is located.
The beach is part of the Setonaikai National Park, established to protect the scenic beauty of the Inland Sea.
Ariake-hama Beach is a 2-kilometer stretch of white sand located along the Seto Inland Sea in Kan'onji, Kagawa. The beach is famous for its 'singing sand' (nakisuna), which emits a sound when walked upon due to the purity of the quartz grains. It is physically situated directly below the Kotohiki Park plateau, which houses the historic Zenigata Sunae coin-shaped sand art. The coastline features a gradual slope and shallow waters, making it a popular spot for summer swimming. Unlike many other beaches in Japan, the area is known for its relatively undisturbed natural environment and clean water quality.

Walk near the shoreline where the sand is slightly damp to better experience the 'singing sand' phenomenon.
Combine your visit with a trip to the Kotohiki Park observation deck to see the beach and the Zenigata Sunae from above.
Check local wind conditions, as strong gusts can make the singing sand effect difficult to hear.
Do not attempt to walk on the Zenigata Sunae sand art itself, as it is strictly protected and viewed only from designated observation areas.
Swimming areas are supervised by lifeguards only during the summer season.
Avoid removing sand or stones from the beach, as the singing sand phenomenon is sensitive to environmental degradation.
