Frequently Asked Questions (FAQ) About the Chibishi Islands
For beginners, we recommend the Chibishi Islands. They’re easily accessible—just a 30-minute trip from Naha at the shortest—and feature many calm inner-reef sites, so you can enjoy your first dive or snorkeling experience with confidence. While the Kerama Islands offer superior water clarity and a greater variety of fish, the travel time is longer, so it’s a good idea to get used to the ocean at Chibishi first before taking on the Kerama Islands.
A half-day tour typically lasts about 3 to 4 hours, including travel time. The standard itinerary involves departing from Tomarin Port in Naha, enjoying diving or snorkeling at the Chibishi Islands, and then returning. Many tours are available in the afternoon, making them an attractive option for filling in free time during your trip.
While diving is enjoyable year-round in the Chibishi Islands, the period from April to October is the best season in terms of both water clarity and temperature. During the summer (July–September), water temperatures reach 28–29°C, and tropical fish become more active. During the winter months (December–February), water temperatures drop, but you can still dive comfortably by wearing a wetsuit or drysuit. During typhoon season (July–September), you’ll need to be mindful of the weather, but tour operators will assess the conditions for you, so there’s no need to worry.
