The Kerama Islands are home to some of the most stunning beaches in Japan. As a diving instructor who used to live in Okinawa, I’m excited to share the beauty of these islands with you. In this guide, I’ll walk you through the three main islands, highlighting their best beaches, how to get there, and where to stay.
What Are the Kerama Islands?

The Kerama Islands are a group of small islands just 40 to 60 minutes by high-speed boat from Naha, the main city on Okinawa’s main island. There are about 30 islands in total, but only three are inhabited: Tokashiki, Zamami, and Aka.
What makes the Keramas truly special is the crystal-clear, emerald green sea known as “Kerama Blue.” This world-class diving destination is part of a national park, with colourful coral reefs and tropical fish that feel like a natural aquarium.
Beyond the beautiful waters, these islands offer a slower, more traditional side of Okinawa. You’ll find peaceful villages, rich nature, and warm-hearted locals who will make you feel right at home.
3 Main Islands of the Keramas
Tokashiki Island

Tokashiki Island is the most accessible from Naha and works well for either a quick day trip or a relaxed overnight stay. It’s well-equipped for tourists and offers a good balance of ocean and mountain experiences.
How to Get There
One round-trip car ferry and two to three round-trip high-speed boats operate daily from Tomari Port in Naha. Departure times and departure points may vary, so please check the official website for the latest information.
- High-speed Boat (Marine Liner Tokashiki): about 40 minutes from Naha
- Car Ferry (Ferry Tokashiki): about 70 minutes from Naha
Top Beaches:
- Aharen Beach: A popular and spacious beach with about 800 meters of white sand right next to a village. Easily accessible by public bus from the port, and surrounded by restaurants and gear rental shops. There’s even a campground right by the beach.
- Tokashiku Beach: Famous for frequent sea turtle sightings in the shallow waters. Calm waves and shallow water make it ideal for kids. You’ll need a taxi to get there, but it’s quieter and more peaceful as a result.
Where to Stay
- Budget: A few hostels around ¥3,000 per person. One campground is available.
- Mid-range: Plenty of guesthouses from around ¥5,000-¥10,000 per person, often with optional meals.
- Luxury: No large resorts, but one upscale option (Kerama Terrace)
Zamami Island

Zamami is the most developed island for tourism in the Kerama islands. It has more accommodation and dining options, and many places cater to English-speaking visitors. The island is a hub for marine activities and beach lovers.
How to Get There
One round-trip car ferry and two to three round-trip high-speed boats operate daily from Tomari Port in Naha. Departure times and departure points may vary, so please check the official website for the latest information.
- High-speed Boat (Queen Zamami): about 50–70 minutes (depends on route)
- Car ferry (Ferry Zamami 3): 90–120 minutes (depends on route)
Top Beaches
- Furuzamami Beach: It is frequently listed in travel guides as one of the world’s best beaches. The contrast between the white sand and Kerama Blue sea is picture-perfect. It’s walkable from the port.
- Ama Beach: A smaller and quieter beach compared to Furuzamami. Great for families or anyone looking to relax. There’s a well-maintained campground nearby, ideal for budget-friendly stays. There’s a high chance you’ll see sea turtles here.
Where to Stay
- Budget: A few hostels around ¥3,000 per person. One campground is available.
- Mid-range: Wide selection of guesthouses around ¥5,000-¥10,000 per person, often with optional meals.
- Luxury: A few high-end accommodations over ¥15,000 per person are available (Sunmar Zamami and Kanusuba Zamami).
Aka Island

If you’re after peace and quiet, Aka Island is the place to go. It’s less commercialised, with untouched nature and some traditional red-tiled houses. You might even spot wild deer wandering the village! Aka’s waters are arguably the clearest in the Keramas, but keep in mind that shops and restaurants are limited.
How to Get There
The same car ferry and high-speed boats that go to Zamami Island also operate to Aka island. Some boats stop at Zamami first, while others stop at Aka Island first. For details, please check the official website.
- High-speed ferry (Queen Zamami): about 50–70 minutes (depends on route)
- Regular ferry (Ferry Zamami 3): 90–120 minutes (depends on route)
Top Beaches
- Nishibama Beach: Aka’s iconic beach, known for its powdery white sand and stunning Kerama Blue water. If you swim a little farther out, you’ll reach a coral reef that’s also used as a diving spot. During peak season, cafés and shower facilities are available.
- Aka Beach: Close to the port and easy to reach. Though the beach itself is small, it’s home to one of Aka’s best corals and sea turtles. Calm waters make it perfect for kids and beginner snorkelers.
Where to Stay
- Budget: No hostels or dorm-style options. Hard to find places under ¥5,000.
- Mid-range: A few guesthouses between ¥5,000-¥10,000 per person.
- Luxury: One small luxury hotel is available (Blue Suites Hanamuro).
Things to Do in the Keramas

While marine activities are the most popular reason to visit, the Kerama Islands are also rich in nature, offering plenty to enjoy on land as well. Even during winter, when swimming might not be an option, there are still plenty of activities to try.
Scuba Diving:
With over 50 dive sites, the Keramas are known for world-class visibility and vibrant coral reefs. Whether you’re into drift diving, looking to get certified, or just want to try it out for the first time, there are options for every level.
Snorkeling:
Join a boat tour to explore offshore spots, or simply snorkel from the beach and still spot colourful fish and coral. Many beaches have lifeguards and rental shops, so even beginners can feel safe and comfortable.
Other Marine Activities:
From stand-up paddleboarding and sea kayaking to jet skiing and parasailing, there’s no shortage of ways to enjoy the sea in the Keramas.
Trekking & Walking Tours:
The islands are home to plants and animals that live only in this region. Guided tours offer a chance to explore the local ecosystem, and there are also night walks and stargazing tours for something a little different.
Whale Watching (Dec–Mar):
From December to March, humpback whales gather around the Kerama Islands. You might see them breach or blow right in front of you. It’s a truly unforgettable experience.
As you have seen, each of the Kerama Islands has its own charm, so you can choose the one that best suits your travel style:
- Tokashiki – Great all-around choice, especially for first-time visitors.
- Zamami – Perfect for those who want to stay active and enjoy fully equipped beaches.
- Aka – Ideal if you’re looking to slow down and connect with nature in a peaceful setting.
What they all share is the stunning Kerama Blue sea and the warm hospitality of the islanders. If you’re already visiting Okinawa, why not go a little further and experience these magical islands for yourself?
