Zamami Island Okinawa: Beaches, Whale Watching & Kerama Blue Waters

What Makes Zamami Island Special

Zamami Island (座間味島) is a small island in Okinawa's Kerama chain, roughly 50 minutes by high-speed ferry from Naha. It's one of the closest outer islands to Okinawa's capital, but it feels worlds apart — white sand beaches with almost no development, water so clear it has its own name (Kerama Blue), and humpback whales that pass through every winter.

Among Okinawa's island destinations, Zamami occupies a sweet spot: remote enough for genuinely uncrowded beaches, close enough for a practical visit without multi-day travel planning. If Ishigaki is Okinawa's adventure hub in the far south, Zamami is the quieter alternative where the draw is simplicity — pristine water, sea turtles, and very little else competing for your attention.

The island has two main beaches (Furuzamami and Ama), a small village with local guesthouses and restaurants, and a whale watching industry that runs from January through March. That's essentially the whole island — and that's the point.

Furuzamami Beach: Michelin-Rated Snorkeling

Snorkeling Conditions and Coral

Furuzamami Beach (古座間味ビーチ) is Zamami's signature beach — over 800 meters of white sand rated two stars in the Michelin Green Guide. According to Visit Okinawa Japan, the beach is one of the top snorkeling spots in the Kerama Islands, with coral and tropical fish accessible right from shore.

The water clarity here is what the Kerama Blue (慶良間ブルー) label refers to — an intense turquoise that comes from the chain's exceptionally clean, nutrient-poor waters. Visibility regularly exceeds 30 meters. The reef starts close to shore, making it accessible even for beginner snorkelers. Lifeguards are on duty during peak summer season, and the calm conditions (no waves) make this one of the more approachable snorkeling beaches in Okinawa.

Facilities and Rentals

Furuzamami is the better-equipped of Zamami's two main beaches. According to Zamami Tourist Information, the beach has snorkel gear rentals, beach chair and umbrella rentals, food vendors, and restrooms with showers. This is the beach to choose if you want a comfortable half-day or full-day setup without bringing everything yourself.

The main thing to know: the walk from Zamami Port to Furuzamami is uphill. In summer humidity, many visitors on TripAdvisor recommend taking the village bus rather than walking. The bus costs ¥300 (~$2) for adults and ¥150 (~$1) for children.

Ama Beach: Sea Turtles and Calm Waters

Ama Beach (阿真ビーチ) is Zamami's other main beach, located on the opposite side of the village from Furuzamami. The walk from the port is flat and takes about 20 minutes, with views of uninhabited islands across the channel.

According to Zamami Tourist Information, Ama Beach is known for sea turtles that frequently graze on seagrass in the shallows. Sightings are common but not guaranteed — calm mornings tend to offer the best chances. The turtles are wild and should not be touched or chased.

Ama is a quieter, more natural beach than Furuzamami. The trade-off is fewer facilities — there are no rental shops or food vendors, so bring your own umbrella, water, and snorkel gear if you plan to stay. The shallow, calm water makes it a good choice for families with young children or swimmers who prefer gentle conditions.

Whale Watching Season (January-March)

From January through March, humpback whales migrate through the waters around the Kerama Islands, and Zamami is one of the primary whale watching departure points in Okinawa. The season typically peaks in February when whale activity is highest.

Tours depart from Zamami Port and operate throughout the whale watching season. Booking in advance is recommended, especially during peak February weekends. Specific operator details and pricing were not confirmed at the time of writing — check with the Zamami Village tourism office or the port information center for current tour options and costs.

Whale watching from Zamami offers a different experience from mainland Okinawa whale watching tours. The boats are smaller, the groups are smaller, and the departure point puts you closer to the whales' migration route. If you're visiting Okinawa in winter, this is one of the strongest reasons to make the ferry trip to Zamami.

When to Visit and What to Expect

Zamami works as a year-round destination, but the experience changes significantly by season.

Season	Highlights	Notes
Winter (Jan-Mar)	Whale watching season	Too cool for extended swimming; whales are the main draw
Spring (Apr-May)	Warming water, fewer crowds	Good balance of beach weather and quiet beaches
Summer (Jun-Sep)	Peak beach and snorkeling season	Hot and humid; lifeguards on duty; ferries book up fast
Autumn (Oct-Nov)	Warm water lingers, crowds thin	Typhoon risk decreases; pleasant conditions

For beach and snorkeling, June through September is the prime window. Water temperatures are warm enough for comfortable extended snorkeling, and Furuzamami's lifeguards are on duty. The downside: summer ferries from Naha fill up quickly, especially on weekends. Book ferry tickets as early as possible.

For whale watching, visit between January and March. February is the peak month. You can combine whale watching with a short beach visit, though the water will be cooler.

Getting Around Zamami Island

Village Bus and Walking Routes

Zamami is small enough that the port, village, and both beaches are reachable on foot or by village bus. According to Zamami Tourist Information, the village bus runs between the port and both Furuzamami and Ama beaches, with tickets at ¥300 (~$2) for adults and ¥150 (~$1) for children. Check the bus schedule at the port information center when you arrive — frequencies are limited.

Ama Beach is a flat 20-minute walk from the port. Furuzamami is uphill and takes about the same time, but the incline makes a significant difference in summer heat. Take the bus to Furuzamami; walk to Ama.

Where to Stay and Eat

Zamami village has a handful of minshuku (民宿, family-run guesthouses) and small pensions. These are simple accommodations — clean tatami rooms, shared facilities, and often home-cooked meals included in the rate. The island does not have resort hotels or large-scale lodging.

For food, the village has a few small restaurants serving Okinawan cuisine and fresh seafood. Options are limited, so if you're staying overnight, choosing a minshuku with meals included simplifies logistics. The port area has a few shops for basic supplies, snacks, and drinks to take to the beach.
