Quick Facts
Location & Map
The Kerama Islands form a volcanic archipelago situated in the East China Sea, roughly 40 kilometers west of Naha, Okinawa. These islands are divided into Tokashiki Village and Zamami Village, offering an accessible yet remote escape. Their strategic position contributes to a unique subtropical climate and serves as a gateway to pristine marine environments.
Getting to the Kerama Islands (from Naha)
All public ferries to the Kerama Islands depart from Tomari Port (泊港, Tomari-kō) in Naha. The terminal, “Tomarin,” is a 15-20 minute taxi ride from Naha Airport or a walk from Miebashi Monorail Station. High-speed (Queen/Liner) and standard car ferries are available. Reservations are highly recommended, especially for high-speed ferries and during peak season, often bookable online two months in advance. A 100 JPY environmental tax applies to Zamami Village (Zamami, Aka) ferry tickets.

Zamami Island (座間味島)
Zamami, the second largest island, is known for its vibrant village life and two famous beaches. Access from Naha is via high-speed Queen Zamami (50-70 mins) or standard Ferry Zamami (90-120 mins).
Key Beaches & Spots on Zamami
Furuzamami Beach, a Michelin Green Guide 2-star site, boasts stunning “Kerama Blue” water and excellent snorkeling. It offers rentals, food, and showers, accessible by a 5-minute bus ride or 20-25 minute walk from the port. Ama Beach is a calmer, shallower spot famous for resident sea turtles feeding during high tide. It’s ideal for respectful turtle watching and offers a peaceful atmosphere with a nearby campsite, a 15-20 minute walk from the port.
Tokashiki Island (渡嘉敷島)
Tokashiki, the largest Kerama island, features two major beaches on its western side. The high-speed Marine Liner Tokashiki (35 mins from Naha) makes it ideal for day trips. Note that Tokashiki Port is on the east coast, requiring a 10-15 minute shuttle bus to the main beaches.
Key Beaches & Spots on Tokashiki
Aharen Beach is the main beach, a beautiful white sand bay with calm, clear water, backed by a village with restaurants and dive shops. It’s excellent for swimming, snorkeling, and marine activities, with access to nearby Hanari island. Tokashiku Beach is quieter and more secluded, known for sea turtle encounters during high tide. It offers a relaxed atmosphere with fewer facilities, ideal for peaceful turtle watching.
Aka Island (阿嘉島)
Aka Island is smaller and quieter, popular with divers and those seeking tranquility. It’s connected by bridges to Geruma and Fukaji islands. Both Queen Zamami and Ferry Zamami from Naha stop at Aka Port. An inter-island ferry, “Mitsushima,” connects Zamami, Aka, and Geruma.
Key Beaches & Spots on Aka
Nishibama Beach is often considered one of the most beautiful Kerama beaches, featuring pristine sand and incredibly transparent water with healthy coral reefs. It offers superb snorkeling and diving. Access is about a 20-30 minute walk from Aka Port, with basic facilities.
Diving, Snorkeling, and Sea Turtles
The Kerama Islands are a world-renowned diving destination, boasting 30-40 meter visibility and over 250 coral species. Dive shops on all main islands offer fun dives and discovery dives. Most major beaches (Furuzamami, Aharen, Nishibama) provide fantastic snorkeling just offshore, revealing diverse tropical fish and coral.
Encountering Green Sea Turtles (ウミガメ, Umigame) is highly probable, especially at Ama Beach (Zamami) and Tokashiku Beach (Tokashiki) during high tide. Remember, it is strictly forbidden to touch, chase, or harass turtles; maintain a respectful distance as per National Park rules.
⚠️ Sea Turtle Etiquette
Always maintain a respectful distance from sea turtles and never touch, chase, or harass them. This is crucial for their well-being and a key rule within the Keramashoto National Park.
Day Trip vs. Staying Overnight
A day trip from Naha is possible, especially to Tokashiki (35-min high-speed ferry), offering a quick taste of “Kerama Blue” and saving accommodation costs. However, it’s often rushed, with significant transit time, limiting exploration and missing the islands’ tranquil atmosphere.
Staying overnight is highly recommended for a more immersive experience. It allows you to explore multiple beaches, enjoy peaceful nights, and have flexibility with activities like turtle watching at optimal high tide. Two nights is often ideal for proper exploration and relaxation, making it a highlight for many visitors.
Seasonality & Timing
The Kerama Islands offer distinct experiences throughout the year. April-May and September-October are ideal, with warm, sunny weather, pleasant water temperatures, and fewer crowds, outside the peak typhoon season.
Peak season (June-August) is the hottest, busiest time, requiring advance bookings. While water is warmest, typhoon risk is highest, potentially causing ferry cancellations. From late December to early April, it’s whale watching season, as humpback whales migrate to breed. Water is cooler, but tours are widely available. Off-peak (November-December) offers cooler weather and fewer tourists, ideal for a peaceful escape, though some shops may have reduced hours.
Insider Tips & Common Mistakes
To ensure a smooth trip, always book ferries in advance, especially high-speed services during peak season, as they sell out quickly. Bring sufficient Japanese Yen from Naha; many smaller shops are cash-only, and ATMs are scarce on the islands. For island exploration, renting an electric bicycle, scooter, or car is advisable due to hilly terrain and limited bus schedules.
Don’t expect 24/7 convenience stores; local shops have limited hours. The sun is extremely strong, so always use high-SPF sunscreen, a hat, and a rash guard. For turtle watching, check tide charts for high tide, which is the best viewing time.
