The 'singing' sound occurs because the sand grains are exceptionally clean and contain high levels of silica, which creates friction when moved.
Local volunteers and residents conduct daily beach cleanups to maintain the purity of the sand, as organic matter or oil can silence the acoustic effect.
The beach is part of the San'in Kaigan Geopark, which showcases the geological history of the Sea of Japan's formation.
It is an official 'Clean Beach' designated by the Japanese Ministry of the Environment.
The beach has been a site for archaeological discoveries, with stone tools dating back to the Jomon period found in the vicinity.
Kotohikihama Beach is a 1.8-kilometer stretch of coastline in Kyōtango renowned for its 'singing sand,' which emits a squeaking sound when walked upon due to high quartz content. The sand's acoustic properties are highly sensitive to pollution, making the beach a symbol of environmental preservation in the region. It is designated as a National Place of Scenic Beauty and a Natural Monument of Japan. The beach features a dedicated hot spring footbath (ashiyu) for visitors to use free of charge. The water quality is consistently rated among the highest in Japan. The surrounding area includes geological rock formations typical of the San'in Kaigan Geopark. It is one of the few places in Japan where camping is strictly regulated to protect the sensitive sand ecosystem.

Walk barefoot to clearly hear the high-pitched squeaking sound of the sand.
Check for the 'singing' effect near the water's edge, where the sand is moist but not saturated.
Bring a towel to use the public footbath located near the parking area.
Avoid visiting after heavy rain or during strong winds, as moisture and debris can dampen the acoustic properties of the sand.
Do not remove sand from the beach as a souvenir, as it is protected to maintain the environment. Littering is strictly prohibited.
