Furuzamami Beach runs for more than 800 metres along the southeastern coast of Zamami Island, in the Kerama Islands archipelago, roughly 40 km west of Naha, Okinawa's capital. It's the longest beach on Zamami and sits inside Kerama Shotō National Park, established on 5 March 2014 — a date chosen to coincide with Japan's "Coral Day." Two of the archipelago's reef areas were also recognised under the Ramsar Convention as wetlands of international importance in 2005, and around 248 coral species, most of them in the Acropora genus, have been recorded across the Kerama Islands. The clear, intensely turquoise water, locally known as "Kerama Blue," owes its transparency to the Kuroshio Current, which keeps plankton levels low, combined with the absence of rivers carrying sediment into the sea, according to Japan's official tourism agency. The beach holds a 2-star rating in the Michelin Green Guide Japan. Zamami village had 892 residents as of October 2020, and tourism — mainly diving, snorkeling and kayaking — employs around 92% of the population.
Just a few metres from the fine white sand, the coral reef drops to about 4 metres before giving way to a sandy seabed, making Furuzamami one of the most accessible snorkeling spots in the Kerama Islands. It's best to enter the water at high tide — the main reef area can become impassable at low tide, precisely to protect the coral. Commonly sighted species include three clownfish varieties (tomato, Clark's and pink-skunk), large shoals of green chromis sheltering in branching coral, butterflyfish, bannerfish, foxface and blue-lipped sea kraits, which hunt moray eels in the reef's crevices. In winter, between December and March, humpback whales can be spotted from observation boats departing Zamami port. Local operators also run glass-bottom boat rides (around ¥4,000/hour), diving trips (around ¥15,000/2 hours) and stand-up paddleboarding (around ¥7,500/2 hours).
The beach is about a 20-minute walk from Zamami port, along a road with some steep sections; a local bus also runs there (¥300 one-way), and there's a small free car park by the beach house with room for around ten vehicles. To reach Zamami from Naha, ferries leave from Tomari Port: the regular "Ferry Zamami" takes about 2 hours (¥2,150 one-way), while the high-speed "Queen Zamami" makes the crossing in 50 to 70 minutes (¥3,200 one-way) — both add a ¥100 environmental tax per adult ticket. The official swimming season runs from early April to the end of October, with lifeguards on duty in the patrolled area according to Zamami's tourist information service; outside that window the water still stays above 20°C into late November. Toilets, showers, a kiosk selling food and drinks, and shops renting snorkeling gear, chairs and parasols are all available by the beach. There are no beach wheelchairs or amphibious matting, however, and the stone path down to the sand ends where the beach begins — worth factoring in when planning a visit with reduced mobility. For those with extra time, Takatsuki-Yama Observatory, about 30 minutes from Zamami hamlet, and Kami-no-Hama Observatory, popular for sunset views and stargazing, are two further stops flagged by Japan's official tourism board.
Furuzamami is far from the only CoveTrip entry in the Kerama Islands, the protected archipelago that gathers several equally crystal-clear coves. On the other side of Japan, more than 1,100 km away, Shirahama Beach on the Wakayama coast shows just how much the country's beach geography changes from region to region.
The official swimming season runs from early April to the end of October, with lifeguards on duty. Outside that window the water stays above 20°C into late November, but without supervision.
By ferry from Tomari Port to Zamami — about 2 hours on the regular "Ferry Zamami" or 50 to 70 minutes on the high-speed "Queen Zamami" — followed by a roughly 20-minute walk or local bus to the beach.
Not necessarily — shops by the beach rent masks, snorkels, fins, chairs and parasols.
