Sunayama Beach is located on Miyako Island in Okinawa Prefecture, Japan, approximately 1,900 kilometers southwest of Tokyo. The beach takes its name from the distinctive sand dune, or "suna-yama" in Japanese, that visitors must cross to reach the shoreline. This natural formation has become one of Miyako Island's most photographed landmarks and represents a defining feature of the Miyakojima coastal landscape.
The beach's most striking natural feature is a large limestone arch that rises from the turquoise waters near the shore. This rock formation, created through centuries of wave erosion, frames the ocean and creates a natural tunnel that has made Sunayama Beach iconic in Japanese tourism photography. The pure white coral sand and crystal-clear waters demonstrate the pristine marine environment characteristic of the Miyako Islands, which are renowned for having some of Japan's cleanest beaches and highest water transparency.
Visitors typically spend time swimming in the calm, shallow waters that extend far from shore, making the beach suitable for families and less experienced swimmers. The arch itself can be walked through at low tide, offering a unique perspective and popular photo opportunity. Snorkeling reveals tropical fish and coral formations, though the beach is primarily valued for its scenic beauty rather than extensive marine biodiversity. The elevated dune provides panoramic views across the beach and surrounding coastline.
Sunayama Beach is located approximately 5 kilometers northwest of Miyako Airport and 7 kilometers from Hirara, the main urban center of Miyako Island. The beach has no direct public transportation access, making rental cars or bicycles the most practical options for visitors. A small parking area accommodates approximately 20 vehicles and can fill quickly during peak season.
From the parking area, visitors walk through a coastal forest path before ascending the sand dune to reach the beach. Basic facilities include portable toilets and outdoor showers, but no lifeguards, food vendors, or equipment rentals are available on-site. Admission to the beach is free. The nearest accommodations and restaurants are found in Hirara or at resort properties scattered along Miyako Island's coastline.
