The Kerama Islands (Tokashiki and Zamami) offer some of Japan's most stunning beaches and marine life, and they're accessible as a day trip from Naha. High-speed boats reach Tokashiki in 35 minutes and Zamami in 60 minutes from Tomari Port. Plan A visits Tokashiki's Aharen Beach for snorkeling in crystal-clear "Kerama Blue" waters. Plan B visits Zamami's Furuzamami Beach, famous for sea turtle encounters. Both islands offer round-trip same-day itineraries with ferry and high-speed boat options. Advance booking is essential during peak seasons (summer and whale watching season January–March).

The Kerama Islands are a national park archipelago just 30–60 minutes from Naha by high-speed boat. This guide covers two day-trip itineraries: Tokashiki Island (best for beginners) and Zamami Island (best for sea turtle sightings), with schedules designed around the ferry timetable so you can maximize your beach time.
Plan A: Tokashiki Island Day Trip (Recommended for First-Timers)
Tokashiki is the largest and closest Kerama island, with the iconic Aharen Beach ranked among Okinawa’s top beaches. The high-speed boat “Marine Liner Tokashiki” departs Tomari Port at 9:00 AM, arriving at Tokashiki Port in about 35 minutes. From the port, a shuttle bus (¥400) takes you to Aharen Beach in 20 minutes.
Spend the morning snorkeling in the renowned “Kerama Blue” waters — visibility often exceeds 30 meters. Snorkel sets can be rented at shops near the beach (around ¥1,000–2,000). After lunch at a local restaurant, catch the return high-speed boat departing at 4:30 PM. The round-trip fare is ¥5,060 (adult, high-speed boat). A slower ferry option is also available at ¥3,380 round trip.
Plan B: Zamami Island Day Trip (Best for Sea Turtles)
Zamami is famous for Furuzamami Beach, where sea turtles are regularly spotted. The high-speed boat “Queen Zamami” departs Tomari Port at 9:00 AM, arriving in about 60 minutes. Furuzamami Beach is a 15-minute walk or short shuttle ride from the port.
The waters here are shallow and warm, ideal for snorkeling even for beginners. Sea turtles frequently appear near the reef edge. For whale watching (January–March), half-day tours depart from Zamami Port (around ¥5,000–6,000). Return on the 4:00 PM high-speed boat. Round-trip fare: ¥7,900 (adult, high-speed boat) or ¥5,800 (ferry).
Which Island Should You Choose?
Choose Tokashiki if you prefer a larger beach with more facilities and a shorter boat ride. Choose Zamami if you want sea turtle encounters and a more intimate island atmosphere. Both islands deliver the signature Kerama Blue experience. During peak summer, book your return boat in advance — ferries fill up fast.
Important Tips for a Kerama Day Trip
Book your return ticket early, especially from June through September. Bring reef-safe sunscreen (chemical sunscreens are discouraged in Kerama waters). Shops and restaurants on both islands are limited — bring cash and snacks. Marine shoes are recommended for rocky entry points. Check cancellation policies as boats may be suspended during typhoon season. For detailed ferry information, see our Kerama Islands Access Guide and Tokashiki Port Guide.
FAQ
Q: Can I visit both islands in one day?
A: It’s technically possible but not recommended. The inter-island boat (Mitsushima) runs infrequently, and you’d have very limited beach time. Choose one island per day trip.
Q: What’s the best season?
A: June through September for swimming and snorkeling. January through March for whale watching (Zamami). April–May and October are pleasant with fewer crowds.
Q: Can I bring luggage?
A: Yes, but travel light for a day trip. There are coin lockers at both ports.
