About the Nagannu Island Tour
Frequently Asked Questions (FAQ)

Q. Can even complete beginners really enjoy the Nagannu Island tour?
Of course! The tours on Nagannu Island offer a wide variety of options with support from guides and instructors, and snorkeling equipment rentals are also available. Since the coral reefs extend across relatively shallow areas in the crystal-clear waters, even beginners and children can enjoy the ocean with peace of mind.
Q. What time does the day trip to Nagannu Island depart?
Although it varies by tour operator, many tours depart from Mie Castle Port between 8:00 and 9:00 a.m. and return between 3:00 and 4:00 p.m. For half-day tours, some operators offer a choice between morning and afternoon departures. For details, please check the official websites of each tour operator for the latest information.
Q. Is the rumor that the water around Nagannu Island is “dirty” true?
Nagan'nu Island is the closest of the Chibishi Islands to the main island of Okinawa and is known for its crystal-clear waters—so clear that it’s hard to believe you’re near the main island of Okinawa. However, since water clarity varies somewhat depending on the weather and season, we recommend visiting during the best season (spring through fall).
