Kabira Bay
Ishigaki Island, Okinawa, Japan
Kabira Bay, the jewel of Ishigaki Island, captivates travelers with its striking gradients of blue and emerald green, both summer and winter. This tropical paradise, awarded by the Michelin Green Guide and ranked among Japan's most beautiful landscapes, hides an exceptionally rich ecosystem beneath its seemingly calm waters. Discover the history, secrets, and regulations of this preserved natural site.
A History Intertwined with Black Pearls and Devotion
The modern history of Kabira Bay is closely linked to a global scientific achievement: the cultivation of the black pearl.
-
A World First: In 1951, due to its pure waters and exceptionally high-quality coral reefs, the local company Ryukyu Pearl Co. successfully cultivated natural black pearls from black-lip oysters (Pinctada margaritifera) for the very first time in the world.
-
A Preserved Craft: The water's relative coolness compared to other regions like Tahiti slows the growth of the oysters. This gives Kabira pearls a unique luster and incomparable fineness.
On the heights overlooking the bay also stands the small Kabira Kannon-do Temple, built in the 17th century. Historically, sailors and locals went there to pray for safe sea voyages and favorable weather, giving the bay a spiritual dimension that is still palpable today.
Glass-Bottom Boats: The Flagship Attraction
The bay is home to over 250 species of coral and a multitude of tropical fish. Glass-bottom boats have become the must-do activity to explore this underwater garden without getting wet.
-
The Experience: Excursions last about 30 minutes. Through the transparent windows on the floor, captains guide visitors over centuries-old coral formations and spot clownfish, rays, and often sea turtles.
-
In Practice: Departures run every 15 to 30 minutes from the main beach. Advanced reservations are not necessary; tickets can be purchased directly at the counters near the Kabira Park parking lot.
Regulations: What is Strictly Prohibited
To protect this ecological sanctuary and ensure everyone's safety, Kabira Bay enforces very strict rules:
-
Swimming and Snorkeling are Forbidden: It is strictly prohibited to swim in the bay. Two major reasons justify this rule: the constant coming and going of glass-bottom boats, which creates a major risk of collision, and the presence of extremely strong and unpredictable undertows heading out to sea.
-
Unauthorized Drone Flights: Due to its status as a protected national park and the high volume of tourists, the use of drones is prohibited without prior official authorization.
-
Touching or Removing Wildlife: It is forbidden to collect coral (even dead pieces) or to disturb the pearl oyster farming areas.
Permitted Activities: Kayaking, Paddleboarding, and Exploring
Although entering the water independently is restricted, many activities remain possible:
-
Kayaking and Stand-Up Paddleboarding (SUP): You can kayak or paddleboard in the bay, but only as part of a paid guided excursion. Snorkeling Ishigaki (operated by Vacances à la mer Ishigaki, based between Kabira Bay and Yonehara Beach) offers tours, as well as a highly regulated kayak and paddleboard rental program within the bay.

-
Independent excursions using your own equipment are prohibited starting from the park beach to avoid accidents with boats.
-
Strolling on the White Sand: You are completely permitted to walk along the shoreline, dip your feet in the water, and enjoy the unique texture of the coral sand.
-
The Observation Deck: Located within Kabira Park, it offers free access to the most famous panoramic view on the island, which is ideal for photography.
If you wish to swim or snorkel independently, it is recommended to travel a few kilometers away to Yonehara Beach, which is perfectly suited and safe for swimming inside the reef (shallow area).
