Snorkeling Ishigaki: Best Reefs, Seasons and Safety Tips

Ishigaki is the hub of the Yaeyama Islands at the far south-western end of Japan, closer to Taiwan than to Okinawa's main island. Coral reefs fringe much of its coastline, and between Ishigaki and neighbouring Iriomote lies Sekisei Lagoon, the largest coral reef area in Japan. Snorkeling is the easiest way to see it: no certification is needed, the water is warm for much of the year, and many of the best reefs are shallow. The same reefs also produce strong currents, though, so knowing where, when and how to go matters more than finding the single "best" beach.

Getting there and getting around

Ishigaki's airport has direct flights from Tokyo, Osaka and a few other mainland cities, and the flight from Naha on Okinawa's main island takes about an hour. From the airport it is roughly half an hour by car to Ishigaki town and the ferry terminal, and airport buses run into town.

A rental car is the most flexible way to reach the north-coast beaches. Local buses run to Kabira and some other north-coast stops, but not often, so check the timetable before relying on them. Many snorkel tours pick guests up from hotels in town, which solves the transport question for boat trips.

Where to snorkel

Yonehara on the north coast is the best-known shore snorkeling spot. Coral starts a short swim from the sand, and on a calm day you will see parrotfish, butterflyfish and other reef fish in water barely deeper than you are tall. But Yonehara is a natural beach rather than a managed swimming area, and currents run strongly near the reef edge and in the channels through it, especially as the tide falls. Go at a calm time, stay well inside the reef, and consider a guided tour for your first swim there.

Sukuji Beach, in the Kabira area, is shallow and sandy and has a managed swimming season with lifeguards and a jellyfish net. It is better for families and paddling than for coral viewing.

Kabira Bay is the island's most famous view, but swimming is not allowed there because of currents and boat traffic, and the bay is also used for black pearl farming. See the coral from a glass-bottom boat instead.

Boat trips reach the reefs you cannot swim to from shore. The most popular options are:

• Sekisei Lagoon reefs, the wide coral areas between Ishigaki and Iriomote, visited by half-day and full-day snorkel tours.
• Manta Scramble, a well-known point off the north-west coast where manta rays gather to be cleaned by small fish. Snorkelers float at the surface while divers watch from below. Sightings are most likely in the warmer months, especially summer and autumn, but are never guaranteed.
• Hamajima, a sandbar between Kohama and Taketomi islands that shows best at low tide, often combined with a snorkel stop nearby.

Ferries from Ishigaki's remote island terminal also make Taketomi and Iriomote easy day trips, and both have their own snorkel tours.
