Long before disembarking, the colour announces the island. Around Miyakojima, the sea displays a gradient the Japanese call "Miyako blue": turquoise over the shallows, cobalt offshore, emerald in the channels. Ships moor at the long Hirara pier, a jetty of about 1.4 kilometres built right out into the lagoon, and crossing this stroke of concrete laid over the clear water is already worth the trip. The island itself surprises with its gentleness: an almost flat coral plateau covered with sugar cane fields rippling all the way to the cliffs, without a single river to cloud the transparency of the sea.

Some of the Most Beautiful Beaches in Japan

About twenty minutes by road from the pier stretches Yonaha Maehama: seven kilometres of flour-fine sand, often cited as the most beautiful beach in the country. The water slopes gently, ideal for swimming, and shade from the facilities is scarce: a hat and sunscreen are a must. In a completely different style, Sunayama must be earned by climbing a small dune: an arch of coral rock frames the sea there, a setting prized by photographers, even if it is less suited to swimming. Each cove on the island seems to have its own personality, and exploring them by taxi or rental car fills an entire day.

Irabu Bridge, Three Kilometres Above the Lagoon

Since 2015, a 3.5-kilometre ribbon of asphalt has spanned the sea to the neighbouring island of Irabu: it is the longest toll-free bridge in Japan. Crossing it with the windows down, above the shades of the lagoon, feels like flying just above the water; the roadway rises in the middle to let boats pass, and this hump adds to the thrill. On the other side, Irabu keeps a slower pace: steep cliffs, isolated coves, renowned dive sites. The Makiyama Observatory offers the best vantage point to take in the bridge, the channel and the reefs at a single glance, especially at the end of the day when the light skims the water.

Capes, Corals and Gardens

To the southeast, the Higashi-Hennazaki peninsula juts out two kilometres between two seas, ending in a lighthouse; the windswept panorama ranks among the widest in the Okinawa archipelago. You walk among flattened grasses and rocks, accompanied by the steady crash of waves on both shores at once, a rare sensation that only such a narrow strip of land can offer. Miyako's coral reefs are among the most vibrant in Japan: a mask and snorkel are often enough, a few metres from shore, to meet butterflyfish and branching corals; local centres rent equipment and know which coves are sheltered depending on the day's wind. And for a shaded break, the municipal botanical garden lines up more than 1,600 tropical species along peaceful paths, led by hibiscus and banyans.

Distances From Hirara Pier

In the evening, as the pier recedes, the lagoon glows with the last reflections and you understand why so many Japanese dream of these shores. Divers, for their part, speak of underwater arches and caves that the light passes through like stained glass; you will have to come back for longer to see for yourself. Miyakojima has neither a castle nor a grand history to tell; it has the sea, in every shade, and that is more than enough to fill a port call — and a memory.
