Barasu Island

Barasu Island is a small coral formation near the Iriomote coast that emerges from the ocean only at low tide, exposing white sand beaches and shallow waters. The flat terrain sits surrounded by turquoise water and reveals intricate coral details.

The island served for centuries as a navigation marker for traditional fishermen traveling between Hatoma and Iriomote islands in the Yaeyama region. This role as a reference point shows the deep connection between the local maritime community and the sea.

The island serves as a meeting point where visitors connect with marine ecosystems and local knowledge about ocean life. Tour leaders here discuss conservation efforts and the relationship between coral reefs and the surrounding Yaeyama waters.

Visits happen between April and October through organized boat tours timed to low tide conditions. It helps to stay flexible with plans, as conditions shift with the daily tidal cycle.

The entire landmass consists of naturally accumulated coral fragments that vanish completely beneath the waves during high tide. This constant appearing and disappearing makes it one of the most dynamic spots in the region.
