The beach is home to a unique geological feature where large limestone rock formations sit directly in the tidal zone, exposed fully during low tide.
The water depth at the reef edge is significantly lower than the surrounding Okinawan waters, allowing for the operation of flat-bottomed glass boats.
Mibaru Beach is situated within the Nanjo City region, an area historically significant as a site of early Okinawan religious legends and pilgrimage routes.
Mibaru Beach is a 2-kilometer stretch of white sand located on the southeastern coast of Okinawa's main island. The beach is characterized by its expansive tidal flats that recede significantly at low tide, revealing a wide coral reef shelf. It serves as a primary hub for glass-bottom boat tours that operate directly from the shoreline to showcase local marine life. The shallow, calm waters are sheltered by the offshore reef, creating a lagoon-like environment suitable for wading. Visitors can access various water sports including sea kayaking and snorkeling services based at the beach entry points. The site is a natural harbor area, historically used by local fishermen before transitioning into a recreational destination. The beach is backed by low-lying limestone cliffs and native Okinawan coastal vegetation.

Consult a tide chart before visiting, as the beach landscape changes drastically between high and low tide.
Wear water shoes, as the exposed reef areas at low tide can be sharp and rocky.
Book glass-bottom boat tours in advance during peak summer weekends to avoid wait times.
Do not attempt to walk out to the deep reef edge without a guide, as currents can change rapidly.
Water sports and glass-bottom boat operations may be suspended during high-wind events or inclement weather.
Avoid touching or stepping on live coral colonies while exploring the tidal flats; carry all trash away from the beach as there are limited facilities.
