The biggest attraction of Kotogahama Beach is the singing sand, which, as its name suggests, makes a sound like a koto (Japanese harp). The phenomenon of singing sand only occurs when very delicate conditions are met: the beach is rich in a certain type of quartz particle, has few impurities, and has the right amount of humidity. The fact that this sound is heard is proof that the beach is clean, and the locals at Kotogahama actively clean up the beach to protect its beautiful environment. The sound of the sand squeaking every time you walk is an unforgettable experience once you experience it.

The beach is shallow and the waves are gentle, so it is a great feature that even families with small children can enjoy swimming in the sea with peace of mind. The white sand and the clear emerald green sea are beautiful enough to be one of Japan's 100 best beaches, and they are also very photogenic. The beach is crowded with beachgoers in the summer, but even in other seasons, you can enjoy the singing sand and just strolling along the beautiful coastline. Especially at dusk, the crimson sky and sea and the quiet sound of the sand create a fantastic landscape.

Adjacent to Kotogahama is the Nima Sand Museum, where you can experience and see exhibits related to singing sand. Here, you can learn about the mechanism of singing sand and about singing sand from all over the world, and you can get a deeper understanding of the charm of singing sand. In addition, the roadside station "Goise Nima" is nearby, where you can enjoy local specialties and gourmet food. It is highly recommended not only as a simple beach, but also as a place that teaches the mystery of nature and the importance of environmental protection.
