Ishigaki’s Turquoise Jewel
Located on Ishigaki Island in Okinawa Prefecture, Kabira Bay (川平湾) is often ranked among Japan’s most beautiful beaches. With its emerald-green waters, white sand shores, and lush surrounding hills, it has earned three stars in the Michelin Green Guide Japan.
Although swimming is not allowed due to strong currents and the presence of valuable black pearl oysters, Kabira Bay remains a must-see destination for its postcard-perfect scenery and relaxing atmosphere.
The Beauty of Kabira Bay
The bay is dotted with small, uninhabited islands and coral reefs, creating a stunning contrast of blue and green shades. The shallow waters are so clear that even from the shore you can see schools of tropical fish swimming near the surface.
The view changes with the tides and sunlight, making every visit feel unique. Morning offers peaceful reflections, while sunset casts golden tones over the bay.
