Okinawa’s subtropical waters are unlike anywhere else in Japan, with coral reefs, white sand, and a color of turquoise more commonly associated with the Caribbean. This guide covers three of the prefecture’s standout beach destinations: Kabira Bay on Ishigaki Island, Manza Beach on the main island, and the Kerama Islands, renowned for some of the clearest water in the world.
1. Kabira Bay, Ishigaki Island
Located on Ishigaki Island in Japan’s remote Yaeyama archipelago, Kabira Bay is famous for its striking gradient of blue and green water, a result of its shallow depth and coral seabed. Swimming is not permitted directly in the bay due to strong currents, but glass-bottom boat tours offer close-up views of coral and tropical fish without needing to enter the water. The bay is also historically known for black pearl cultivation, and several shops nearby sell pearls harvested from local farms. The surrounding lookout points offer some of the best photo opportunities in all of Okinawa, particularly in the late morning when the sun is high enough to bring out the water’s full color range.
2. Manza Beach, Okinawa Main Island
Manza Beach sits on the western coast of Okinawa’s main island, within one of the prefecture’s most established resort areas. Its calm, shallow water and easily accessible coral reef make it a popular spot for snorkeling and beginner-friendly water sports, with several dive shops offering guided reef tours just offshore. Unlike the more remote outer islands, Manza Beach is set up for convenience, with beachfront resorts offering direct beach access, equipment rental, and dining without needing to travel far. It’s a practical choice for travelers who want strong beach access without the extra ferry or flight time required to reach Okinawa’s outer islands.
3. The Kerama Islands
A short ferry ride from Naha, Okinawa’s capital, the Kerama Islands are protected as a national park and known for a shade of water locals call “Kerama Blue” — regularly ranked among the clearest in the world by visibility measurements. The islands (Zamami, Aka, and Tokashiki are the most visited) offer excellent snorkeling and diving directly from the beach, along with a chance to spot sea turtles in the shallows. Between January and March, the surrounding waters are also a breeding ground for humpback whales, and whale-watching boat tours run regularly from Naha during this season. A day trip is possible, but an overnight stay allows time to properly explore more than one beach across the small islands.

Quick Tips for Visiting
- Swimming is prohibited in Kabira Bay itself — plan on a glass-bottom boat tour rather than beach time there.
- Book Kerama Islands ferry tickets in advance during peak summer months and whale-watching season (January-March).
- Reef shoes are recommended at most Okinawa beaches, as coral and rocks are common close to shore.
- Ishigaki and the Kerama Islands both require a separate flight or ferry from Okinawa’s main island — factor this into your itinerary.
