Japan's tropical paradise — coral reefs, turquoise waters, and ancient Ryukyuan culture
A chain of islands that bridges Japan and the tropics
Okinawa Prefecture is Japan's southernmost region, a stunning archipelago of more than 160 islands stretching across the East China Sea between Kyushu and Taiwan. Known as the Ryukyu Islands, these volcanic and coral outcroppings spent centuries as an independent kingdom — the Ryukyu Kingdom — before becoming part of Japan in 1879. That distinctive history has left Okinawa with a culture, cuisine, and dialect unlike anything else in Japan.
The main island, also called Okinawa Honto, is home to the prefectural capital Naha and the iconic reconstructed Shuri Castle, a World Heritage Site that served as the royal residence of Ryukyuan kings. Beyond the capital, the island is lined with white-sand beaches, sacred stone tombs called gusuku, and dense subtropical forests. The residents of Okinawa are world-famous for their extraordinary longevity, a phenomenon studied by researchers around the globe and attributed to diet, community, and a lifestyle philosophy known as ikigai.
The outer island groups — including Yaeyama, Miyako, and Kerama — offer even wilder, more pristine experiences. Iriomote Island, part of Yaeyama, is almost entirely national park and is home to the extremely rare Iriomote cat, found nowhere else on earth. The Kerama Islands are famous for their "Kerama Blue" — a shade of ocean so vivid it seems invented by an artist. Whether you come for diving, surfing, cultural immersion, or simply to unwind on a secluded beach, Okinawa rewards every kind of traveller.
Traditional Okinawan arts — including the textile craft of bingata dyeing, ryukyuan glassware, and the haunting three-stringed sanshin lute — are alive and celebrated throughout the prefecture. Local festivals such as Eisa (a spirited summer drum dance) and the Naha Tug-of-War (a Guinness World Record holder) provide once-in-a-lifetime cultural encounters.
Six remarkable sub-islands, each with its own personality
The gateway to Yaeyama, Ishigaki dazzles with powder-white Kabira Bay (off-limits to swimmers to protect its rare black pearls), vibrant coral reefs beloved by divers, and a mountain backdrop of lush jungle. The local beef, Ishigaki-gyu, is among Japan's finest wagyu.

The surrounding sea glows in impossible shades of cyan and turquoise, ideal for kite-surfing and snorkelling.

Whale watching (Jan–Mar)Over 90% of Iriomote is covered in subtropical jungle and mangrove forest, making it Japan's most pristine wilderness island. The resident Iriomote cat — classified as critically endangered — is the island's legendary resident. Canoe the Urauchi River through jungle canopy for a true adventure.

Kume is quieter and less visited, ideal for those seeking authenticity.

Okinawa's underwater world is among the richest in the Pacific. The Ryukyu Arc sits atop one of the world's largest and most biodiverse coral reef systems, sheltering over 400 species of coral and more than 1,000 species of fish. The Kerama Shoto National Marine Park, designated in 2014, protects some of the most pristine reefs accessible to recreational divers anywhere in the world.
Above the waterline, Iriomote-Ishigaki National Park covers vast tracts of subtropical lowland forest, mangrove rivers, and sea-grass beds. The endemic Iriomote cat — a small, solitary wildcat descended from ancient lineages — symbolises the fragile uniqueness of island life. Dugongs, sea turtles, and whale sharks pass through these waters seasonally.
UNESCO's 2021 inscription of Amami-Oshima, Tokunoshima, Iriomote-jima, and northern Okinawa-jima on the World Heritage list recognised their extraordinary biodiversity and the presence of numerous species found nowhere else on Earth.
Connections from across Japan and beyond
Naha Airport (OKA) is Okinawa's main international hub, receiving direct flights from Tokyo (Haneda/Narita, ~2.5 hrs), Osaka (~1.5 hrs), Fukuoka (~1 hr), and international routes from Taiwan, South Korea, China, and Hong Kong. Budget carriers Jetstar, Peach, and ANA/JAL all serve Okinawa.
Regular ferry services depart from Osaka, Kobe, and Kagoshima to Naha Port. The journey from Osaka takes approximately 48 hours but is a scenic and affordable option. Ferries also connect the main island to the outer islands, with A-Line and Marix Line operating inter-island routes.
Naha serves as the gateway hub for the outer islands. High-speed ferries reach Kerama (35–50 min) and Kume Island (3.5 hrs). Smaller island-hopping flights depart from Naha on Japan Air Commuter, RAC, and ANA Wings. Miyako and Ishigaki also have their own airports for direct connections from Tokyo and Osaka.
Everything you need to know before you go
Okinawa's subtropical climate means it is warm year-round, but the best window is March to May and October to November, when temperatures are comfortable (22–28°C), crowds are smaller, and sea conditions are ideal for diving.
Summer (June–September) is hot and humid, with a rainy season in June and typhoon season peaking August–September. Winter (December–February) is mild (15–20°C), excellent for whale watching and fewer tourists, though some outer island ferries reduce frequency.
