Kerama Islands

This section is being updated and will be available shortly.

The Kerama Islands (Kerama Shoto) are a cluster of some 20 islands and islets lying about 40 kilometres west of Naha, of which Tokashiki, Zamami and Aka are the main inhabited ones. Designated a national park in 2014, they are celebrated for water so vividly transparent it gave the world the term "Kerama Blue."

With healthy coral reefs, resident sea turtles and seasonal humpback whales, the Keramas are among the finest marine destinations in Japan, yet remain easy day trips or short escapes from the capital.

The Keramas offer arguably the clearest, most beautiful sea within easy reach of Naha, making them a bucket-list marine destination. Snorkelling and diving here reveal pristine reefs, turtles and, in winter, whales.

White beaches, uncrowded islets and national-park protection combine natural splendour with accessibility, letting travellers experience world-class waters without a long journey.

Tokashiki's Aharen and Tokashiku beaches, Zamami's Furuzamami Beach, and Aka's Nishibama Beach are the standout sands. The islands' observation decks give sweeping Kerama Blue panoramas.

Snorkelling with turtles, diving vibrant reefs, kayaking to uninhabited islets, and winter humpback whale watching are the defining experiences.

Snorkel and dive the reefs, swim at the celebrated beaches, and take boat or kayak trips to uninhabited islets. Hike to island viewpoints for panoramas, and in winter join a whale-watching cruise.

Island-hop between Zamami and Aka by local boat, enjoy fresh seafood in the villages, and stargaze under dark island skies.

Furuzamami Beach on Zamami, Aharen Beach on Tokashiki, and Nishibama Beach on Aka are the essential beaches. The observation decks such as Zamami's Kaminohama give the classic Kerama vistas.

The uninhabited islets like Gahi and Agenashiku, prime for snorkelling, and the winter whale-watching grounds are further must-experiences.

The quieter Ama Beach on Zamami and Tokashiku Beach on Tokashiki offer calm turtle-filled waters away from the busiest spots. The tiny bridge-linked island of Geruma near Aka is a peaceful detour.

Kayaking to near-private islet beaches and finding secluded coves reward those willing to explore beyond the main landing beaches.

The Kerama villages preserve traditional Okinawan fishing culture, eisa drumming and seasonal festivals. Wartime memorials on Tokashiki and Zamami mark the tragic events of the 1945 battle.

Interacting with the tight-knit island communities and learning about their marine-conservation ethic offers cultural depth beyond the beaches.

As a national park, the Keramas protect exceptional coral reefs, clear waters, sea turtles and migrating humpback whales. The islands' hills, forests and coastal trails add terrestrial nature to the marine wealth.

The reefs are healthy and diverse, and the surrounding sea's clarity makes even shore snorkelling extraordinary.

Calm, shallow beaches with easy turtle sightings make the Keramas superb for families. Snorkel and glass-bottom boat tours suit children, and the small island scale feels safe and manageable.

Simple guesthouse stays and gentle waters offer a relaxed family beach holiday close to Naha.

The Keramas are tranquil islands with minimal nightlife: a few izakaya and small bars in the villages of Zamami, Aka and Tokashiki. Evenings centre on quiet dinners and stargazing.

Those seeking bars and clubs should base themselves in Naha; the islands' appeal is peace and dark, starry skies.

The observation decks on Zamami and the beaches of all three main islands deliver the iconic Kerama Blue shots. Underwater photography of turtles and coral is superb.

Sunsets from the western shores, and star photography under dark skies, are memorable, while whale watching offers dramatic winter images.

The Kerama Islands were fishing and farming communities within the Ryukyu sphere for centuries. They saw tragic events during the 1945 Battle of Okinawa, including coerced mass suicides, now memorialised.

In 2014 the islands and their surrounding waters were designated Kerama Shoto National Park, recognising their outstanding coral reefs and cementing their role in Okinawan eco-tourism.

Kerama culture revolves around the sea, with fishing, marine stewardship and traditional Okinawan customs at its heart. Community festivals feature eisa and folk music.

A strong conservation ethic, tied to national-park status and reliance on healthy reefs, shapes how the islanders welcome visitors and protect their waters.

April to October is best for beaches and snorkelling, with the warmest, clearest water from May to September. Winter, December to April, is humpback whale-watching season.

Summer is busiest; late spring and early autumn balance warm seas with fewer crowds. Typhoons (July to October) can disrupt ferries.

The subtropical climate brings hot, humid summers often above 30 C with typhoon risk, and mild winters around 18 to 20 C. The rainy season falls around May to June.

Sea temperatures stay warm from late spring into autumn. Winter is cooler and breezier but clear, ideal for whale watching.

The islands hold seasonal village festivals with eisa drumming and folk performances, and whale-watching season is a major winter-to-spring draw. Occasional marine and sporting events occur.

Dates vary by island and year, so check the respective village tourism sources for the current calendar.

For a day trip, ferry to Zamami or Tokashiki, snorkel at the main beach, and hike to a viewpoint before returning to Naha. With two or three nights, base on one island and boat-hop to others and to uninhabited islets.

In winter, dedicate a morning to a whale-watching cruise, and reserve evenings for island dinners and stargazing.

A single day covers one island's headline beach, but two to four days let you explore multiple islands, reefs and islets at a relaxed pace.

Divers and marine enthusiasts often stay longer to sample the full range of Kerama dive sites.

Ferries from Naha's Tomari Port serve the main islands: Zamami in about 50 minutes by fast ferry, Aka similarly, and Tokashiki in around 35 minutes by high-speed ferry. Book ahead in peak season.

Local boats link Zamami and Aka within the group. There is no airport in the Keramas.

On each island, beaches and villages are close, with shuttle buses meeting ferries in season and rental bicycles, scooters and cars available. Boats and kayaks reach outer beaches and islets.

Inter-island travel uses local ferries; distances on land are short and easily managed on foot or by scooter.

Tomari Port in Naha is the mainland gateway, with ferries to Zamami, Aka and Tokashiki. Each island has its own small port as the arrival point.

There is no rail or airport; ferries and local boats are the sole transport links to and within the Keramas.

Beaches and viewpoints are open at all times, while facilities, operators and shops keep seasonal daytime hours. Ferries run scheduled timetables, with fewer sailings in winter and rough weather.

Last ferries to Naha can be mid-afternoon, so day-trippers must plan carefully; confirm current schedules before travelling.

The beaches are free, though small environmental cooperation fees may apply and equipment rental costs extra. Round-trip fast ferry fares from Naha run roughly 6,000 yen depending on island.

Snorkel and whale-watching tours cost about 5,000 to 7,000 yen; confirm current ferry and tour prices with operators.

Each main island's village has a modest selection of izakaya, cafes and shops serving Okinawan dishes, fresh seafood and island soba. Options are limited, especially off-season.

Beach kiosks operate in summer, and small supermarkets stock basics; plan meals around opening hours, as choices are few.

Fresh reef fish, Okinawa soba, sea grapes and island vegetables define the cuisine. Simple, seafood-focused cooking reflects the day's catch.

Awamori and Orion beer accompany meals, and sata andagi doughnuts are a common island sweet across the group.

Guesthouses (minshuku), pensions and small inns cluster in the villages of Zamami, Aka and Tokashiki, most family-run and comfortable rather than luxurious. Book ahead in peak season.

Staying overnight lets you enjoy the beaches and stars after day-trippers leave; many visitors nonetheless day-trip from Naha.

A day trip's main cost is the ferry (around 6,000 yen return) plus rentals and lunch, roughly 8,000 to 12,000 yen. Overnight guesthouse stays are moderate, often 5,000 to 10,000 yen per person including meals.

Beaches and viewpoints are free, keeping costs reasonable outside tours and ferries.

Shopping is limited to small village shops selling island snacks, awamori, salt and marine-themed souvenirs. There are no large stores in the Keramas.

Buy essentials in Naha beforehand; on the islands, support the few local shops for gifts and supplies.

Heed beach flags and swim in designated areas, as currents strengthen beyond the reefs. Watch for jellyfish in summer, never touch coral or turtles, and use reef-safe sunscreen.

Strong sun demands diligent protection, and typhoon forecasts should be checked in season, as storms can cancel ferries and strand visitors.

Main beaches and villages have some accessible paths, but hilly terrain, boat boarding and simpler facilities limit full accessibility. Seasonal shuttles help cover distances.

Contact guesthouses and operators ahead about accessible options; scooters and shuttles ease land mobility.

Japanese is standard; some English is understood at operators and guesthouses used to visitors, but limited generally. A translation app is helpful.

Basic Japanese courtesies are warmly received across these small, friendly islands, and point-and-order works in eateries.

Choose one island as a base rather than rushing between several, book ferries and lodging ahead in summer, and carry cash given limited card acceptance. Note the last ferry if day-tripping.

Use reef-safe sunscreen, bring your own snorkel gear if possible, and stay flexible around typhoon forecasts in stormy months.

Bring swimwear, a rash guard, reef-safe sunscreen, a hat, water shoes and snorkel gear. Cash is important due to limited card acceptance.

Water, snacks, a light layer for ferries and evenings, and a dry bag for boat and kayak trips complete the kit.

As a national park, the Keramas depend on pristine reefs: never touch coral or turtles, use reef-safe sunscreen, and follow operator guidance. Pay environmental fees and take all litter home.

Support small local businesses, conserve water and power, and keep noise down to respect wildlife and the quiet communities.

Within the group, Zamami, Aka and Tokashiki are easily combined, along with bridge-linked Geruma and uninhabited islets like Gahi and Agenashiku. Naha's sights are a short ferry ride away.

The wider Okinawa main island, with Shuri Castle and Kokusai Street, complements a Kerama trip.

The village tourism associations of Zamami, Aka and Tokashiki and the Kerama Shoto National Park provide ferry timetables, beach and reef conditions, tour operators and whale-watching schedules. Check them for current details.

Tomari Port in Naha and each island's information centre offer maps and up-to-date guidance, especially on weather-related ferry cancellations.
