FAQ
What is 'Kerama Blue'?
Kerama Blue refers to the extraordinary clarity and vivid blue color of the water around the Kerama Islands, considered some of the clearest water in Japan with visibility often exceeding 40 meters.
How do I get to the Kerama Islands?
Fast ferries from Naha (Okinawa main island) reach Zamami in about 50 minutes. Dive operators on Zamami and Tokashiki run daily trips.
Can beginners dive here?
Yes, the shallow depth, calm conditions, and easy cave entrance make this one of Japan's most beginner-friendly dive sites.
How far are the Kerama Islands from Naha?
The Kerama Islands lie approximately 30 kilometres west of Naha. Fast ferries reach the main islands (Tokashiki, Zamami, Aka) in 50 to 70 minutes, while dive boats typically take 60 to 90 minutes to reach the closer dive sites in the channel area. Several Naha-based operators run dedicated day-trip dive boats that depart early morning and return by late afternoon, making Kerama diving accessible without overnight stays on the islands.
What is Kerama Blue?
Kerama Blue refers to the extraordinary water clarity characteristic of the Kerama Islands area, where visibility frequently exceeds 40 metres and sometimes reaches 50 metres or more. This clarity results from the islands' position in the Kuroshio Current's influence zone, with limited river runoff and deep oceanic water surrounding the island group. The blue colour and transparency of the water have become a branded attraction and are considered among the finest in Japan.
