Okinawa Island, the main island of Japan's southernmost prefecture, is a subtropical strip of coral beaches, castle ruins and forest about 107 kilometers long. It lies roughly 640 kilometers south of Kyushu and 500 kilometers northeast of Taiwan, and for some 450 years it was the heart of the Ryukyu Kingdom, whose palace at Shuri still looks down on the capital, Naha.
Visitors come for the sea, with snorkeling and diving around the Kerama Islands, beaches along the west coast and the Okinawa Churaumi Aquarium in the north, and for a food and music culture quite distinct from mainland Japan. Vacation rentals range from city apartments in Naha to beach houses and villas in Chatan, Onna and Motobu. They suit families, couples and groups who want to drive the island at their own pace, within the limits of Japan's private-lodging rules.
Naha, the prefectural capital on the southwest coast, is the easiest base for a first visit or a trip without a car. The airport, the Yui Rail monorail, the ferry piers for the Kerama Islands and the shops and restaurants around Kokusai-dōri are all close, and apartments are plentiful.
Chatan, a short drive north, has a lively seafront with Sunset Beach, cafés and evening sunsets over the East China Sea. Beyond it, Onna and the central west coast form the island's main resort strip, with sandy coves, the coral-limestone cliffs of Cape Manzamo and many condos and beach houses suited to family holidays.
The Motobu Peninsula and Nago in the north put the Churaumi Aquarium, Emerald Beach and the Nakijin Castle ruins on your doorstep. Yanbaru, the forested far north, is quiet and rural, best for travelers who want hiking, rivers and a slower pace.
From 1429 to 1879 the island was the center of the Ryukyu Kingdom, a seafaring state with close ties to China and Southeast Asia. Japan's Satsuma domain invaded in 1609, and in 1879 Japan annexed the islands as Okinawa Prefecture. The Battle of Okinawa, fought from April to June 1945, devastated the island; it then remained under US administration until 1972, and facilities used exclusively by the US military still cover about 15 percent of the island.
Shuri Castle, on a hill above Naha, was the royal palace. Almost completely destroyed in 1945, it was largely rebuilt from 1992, and its site belongs to the Gusuku Sites and Related Properties of the Kingdom of Ryukyu, a UNESCO World Heritage Site since 2000 that also includes the Nakijin, Zakimi, Katsuren and Nakagusuku castle sites and the sacred site of Sefa-utaki. On 31 October 2019 a fire destroyed the main hall and several other buildings. Rebuilding began in 2020, and the new main hall opens to the public from late November 2026.
Coral reefs fringe much of the coast, and the west side between Chatan and the Motobu Peninsula has the greatest choice of beaches, from Sunset Beach in Chatan to Zanpa, Manza and Emerald Beach in Ocean Expo Park. Many popular beaches open for swimming in March, and diving and snorkeling are possible all year, with sea temperatures from about 21 degrees Celsius in February to nearly 30 in August. Swim in supervised areas and take care near reef edges and channels, where currents can be strong.
The Kerama Islands, a group of 36 islands about 30 kilometers off Okinawa Island, became Kerama Shotō National Park in 2014. Tokashiki, Zamami, Aka and Geruma are inhabited, regular ferries run from Naha, and the reefs and exceptionally clear water draw snorkelers and divers. In winter, humpback whales gather in the surrounding waters.
The Okinawa Churaumi Aquarium opened in 2002 in Ocean Expo Park on the Motobu Peninsula. Its main tank, the Kuroshio Sea, holds 7.5 million liters of water and is home to whale sharks and manta rays among many other species. The aquarium is roughly 90 kilometers from Naha, about two hours by car. Nearby, the Nakijin Castle ruins are known for some of Japan's earliest cherry blossoms, in January and February.
Farther north, Yanbaru National Park, created in 2016 in the villages of Kunigami, Ōgimi and Higashi, protects subtropical forest, rivers and mangroves. In 2021 the northern part of Okinawa Island was inscribed as a natural World Heritage Site together with Amami-Ōshima, Tokunoshima and Iriomote islands. Forest walks, waterfalls and mangrove kayaking are the main draws, and the roads here are much quieter than in the south.
Naha Airport (OKA), about four kilometers west of central Naha, has flights from across Japan and from Taiwan, Hong Kong, South Korea, mainland China and several Southeast Asian cities; a second runway opened in 2020. The Yui Rail monorail runs 17 kilometers from the airport through central Naha to Shuri and on to Tedako-Uranishi in Urasoe.
Outside Naha a car is by far the easiest way to explore. The Okinawa Expressway runs north to Nago, local buses connect the towns more slowly, and traffic in and around Naha can be heavy at rush hour. Driving is on the left, and visitors should confirm before traveling that their license is valid for driving in Japan. Ferries from Naha serve Tokashiki, Zamami and Aka in the Kerama Islands.
Okinawa has a humid subtropical climate with long, hot summers and mild winters; Naha's average annual temperature is around 23 degrees Celsius. The rainy season usually runs from mid-May to late June, with frequent showers rather than all-day rain. Typhoons are possible from June through September and can disrupt flights and ferries, so flexible plans help in those months.
Spring and autumn bring warm days and comfortable evenings, and the sea stays inviting well into autumn. Winter is cooler, and northerly winds can make it feel colder than the thermometer suggests, but it is the season for humpback whales around the Kerama Islands and for early cherry blossoms in January and February. Beach season at the main resort beaches begins in March.
Short-term stays in private homes anywhere in Japan fall under the Private Lodging Business Act, in force since June 2018. Operators must notify the local authority, which is the prefecture or, in cities such as Naha, the city itself, and a home registered under the act may host guests for no more than 180 nights in each year beginning on 1 April. Prefectures and some cities, including Naha, can also limit by ordinance the periods or areas in which such homes operate, to protect residential neighborhoods from noise and similar problems, so local rules may differ.
Other holiday homes and villas are licensed as lodging under the Inns and Hotels Act, which is not bound by the 180-night limit. Whichever category a property falls into, it operates under a registration or license number, and asking the host for it before booking is a simple way to confirm the rental is legitimate.
Naha is best without a car, with the airport, monorail and Kerama ferries close by. Chatan and Onna on the west coast suit beach holidays and families. Motobu and Nago are ideal for the Churaumi Aquarium and the north, and Yanbaru suits travelers who want forest and quiet.
April and October to November usually combine warm weather with fewer storms. The rainy season runs from about mid-May to late June, typhoons are possible from June through September, and winter, though cooler, is the season for whale watching and early cherry blossoms.
In Naha you can manage with the Yui Rail monorail, taxis and buses. Beyond the capital a rental car makes a big difference, as beaches, the Churaumi Aquarium and Yanbaru are spread along a long island and buses are slow. Check before you travel that your license is valid in Japan.
The Okinawa Churaumi Aquarium, in Ocean Expo Park on the Motobu Peninsula, is roughly 90 kilometers from Naha, about two hours by car using the Okinawa Expressway. Express buses also make the trip but take longer.
Yes. The castle grounds, gates and walls above Naha remain open to visitors, and the site is part of a UNESCO World Heritage listing. The main hall, destroyed by fire in 2019, has been rebuilt and opens to visitors from late November 2026.
Regular ferries from Naha serve Tokashiki, Zamami and Aka, the main inhabited islands of the Kerama group, about 30 kilometers off Okinawa Island. Many visitors go for a day of snorkeling, while others stay a few nights to enjoy the reefs and quiet villages.
Okinawan cooking differs from mainland Japanese food. Look for Okinawa soba, a wheat-noodle soup often topped with stewed pork ribs; goya chanpurū, a stir-fry with bitter melon; rafute, slow-braised pork belly; taco rice, a postwar favorite; and awamori, a spirit distilled from Thai-style long-grain rice.
Yes. Homes registered under Japan's Private Lodging Business Act can host guests for up to 180 nights a year, and prefectures or cities may add local limits. Other villas are licensed under the Inns and Hotels Act instead. Either way, a legitimate rental has a registration or license number you can ask for.
