Okinawa Shoto (Kerama Islands)
Experience the Crystal Clear "Kerama Blue"

The Kerama Islands consist of over 20 islands of varying sizes, located 30-40 kilometers west of Naha City. Well known for the clarity of its world class oceans - the vibrant colour being termed “Kerama blue” - these islands are a haven for snorkelling and divers as the underwater scenery is unlike anywhere in the world. Tropical fish and other sea life swim throughout the coral reefs, in water so clear you don't even need to be in it to see this! Magnificent views abound from the observatories on Tokashiki Island, Zamami Island, Aka Island, and Geruma Islands, with early mornings or evenings being the best time to experience the morning sun and moonlit night reflecting off the sea.
ZAMAMI ISLAND
Most Popular of the Kerama Islands
[Access: 50 minutes by express ferry from the main island of Okinawa]
Zamami Island is the second largest of the Kerama Islands. Well-known for its beautiful white sand and clear waters, the island's most popular beaches are within walking distance from the village which surrounds the port. Observation decks provide uninterrupted views of the Kerama Island landscape from the forested interior of the island. The stunning Kerama Blue sea is designated as part of a national park and offers marine activities year-round and whale watching in the winter.
Island highlights include:
TOKASHIKI ISLAND
The Gateway to the Kerama Islands
[Access: 70 minutes by ferry from the main island of Okinawa]
Tokashiki Island is the largest of the Kerama Islands. Although slightly lagging behind Zamami's popularity, Tokashiki offers several nice beaches while its interior is mostly covered by forested hills and offers a few hiking trails and observation decks. Tokashiki Island features a rugged landscape with well-developed forests where visitors can enjoy not only marine activities, but also trekking and nature walks.
Island highlights include:
AKA ISLAND
A Treasure Trove of Amazing Sights
[Access: 50 minutes by high-speed boat, around 90 minutes by ferry from the main island]
Aka Island is the smallest of the Kerama Islands, designated as a national park. The island has a circumference of approximately 12 kilometers, and rental bicycles are a convenient and popular option for accessing beaches and sightseeing. Connected to Geruma Island by bridge, the short ride over is worth it for extended sightseeing. Diving is the perhaps the biggest attraction around Aka, as coral reefs surround most of the island, with calm waters and abundant colourful tropical fish. Swimming with sea turtles is not unheard of on Aka Island and uninterrupted views of the Kerama Island landscape can be viewed from both the large bridge at the entrance of the idlans, and from observation decks dotted around the island.
Island highlights include:
GERUMA ISLAND
Isolated Island Surrounded by Rich Nature
[Access: 50 minutes by high speed boat & 90 minutes by ferry from the main island of Okinawa]
Part of the Kerama Islands, Geruma Island is the smallest of the inhabited islands and is connected to Aka Island by bridge. It is simple, un-touristic and feels like a time slip to a simpler age. The village of Geruma is tiny - you can walk around it under 5 minutes! What it may lack in convenience, it definitely makes up for in peace and serenity. Crossing the Aka Bridge you can stroll through the quiet village and fields with the Fukugi trees standing tall, time flows slowly, creating a somewhat nostalgic feel. The nature on the island remains untouched, as it is a protected area for the local Kerama deer population, which have been designated as a National Natural Monument.
