Quick answer: Okinawa Prefecture is a chain of subtropical islands in the far south of Japan, with Naha as its capital on the main island. It is known for Shuri Castle, Churaumi Aquarium, coral beaches, the Kerama, Miyako and Yaeyama islands, Okinawa soba and awamori. Naha is about three hours from Tokyo and about two hours from Osaka by air.

Okinawa at a Glance

Okinawa is a world apart from the rest of Japan, with a warm climate, a turquoise sea, white sand beaches and a distinct culture that blends Japanese, Chinese and Southeast Asian influences. The prefecture includes about 160 islands, and the main island is a long strip of coast, hills and small towns with Naha, the capital, at its southern end.

Visitors come for the beaches, the snorkeling and diving, and the relaxed island life, but also for the history and food. Naha has castle ruins, a lively market street and a lot of good restaurants, and the outer islands are a world of their own, reached by a short flight or ferry from Naha.

History and Culture of Okinawa

Okinawa was once the Ryukyu Kingdom, an independent trading state that flourished from the fifteenth century as a hub between Japan, China and Southeast Asia. Its court at Shuri Castle developed refined arts, dance, music and cuisine, and the Shuri Castle guide explains the history of the castle and its reconstruction after the 2019 fire. The kingdom was absorbed by Japan in 1879, and the Gusuku sites are now a UNESCO World Heritage listing.

Okinawan culture has its own language, music and crafts. The sanshin, a three-stringed instrument, accompanies folk songs, and karate began here as a martial art. Okinawa is also known for its long-living population, and the local diet of vegetables, tofu and seaweed is often linked with good health, as described in the Okinawan cuisine guide.

Getting to Okinawa and Moving Around

Naha Airport has direct flights from Tokyo in about three hours, from Osaka in about two hours and from Fukuoka in about an hour and a half, and many flights from Asia. The airport is connected to the city by the Yui Rail monorail, which reaches the Kokusai Dori area in about 15 minutes and Shuri in about 30 minutes. Ferries connect Naha with the Kerama islands and others.

A rental car is the most practical way to see the main island, since public transport outside Naha is limited, though there are buses and tour options. For the outer islands, short flights from Naha reach Miyako and Ishigaki in about an hour, and from Ishigaki small boats go to Taketomi and Iriomote. Remember to check weather forecasts, because typhoons can stop ferries and flights.

Top Sights in Okinawa

Shuri Castle is the former royal palace of the Ryukyu Kingdom, with red buildings and sweeping views, and Naha's Kokusai Dori is a long street of shops and restaurants, as covered in the Kokusai Dori guide. Makishi Public Market is a lively seafood hall where you can buy fish and have it cooked upstairs.

The Churaumi Aquarium in Motobu is among the largest in the world, with a huge tank where whale sharks and manta rays swim, as described in the Churaumi Aquarium guide. Cape Manzamo, Nakijin Castle ruins and Kouri Island are scenic stops in the north. Outer islands include the Kerama islands and Miyako Island, as well as Ishigaki, Taketomi and Iriomote.

What to Eat and Drink in Okinawa

Okinawa soba is a thick wheat noodle in a clear pork broth, topped with braised pork ribs or stewed pork belly, and it is a staple lunch. Goya champuru, a stir-fry of bitter melon, tofu, egg and pork, is the island's signature home dish, and rafute, pork belly simmered in sugar and soy sauce, is a rich comfort food. Umibudo, or sea grapes, are tiny green beads that pop in the mouth.

Taco rice, a local invention of taco fillings over rice, and Blue Seal ice cream are fun treats, and tropical fruit like pineapple, dragon fruit and mango is excellent in season. Awamori, a millet-based spirit distilled in Okinawa for centuries, is the local drink, and the awamori guide explains how it is aged and served.

Festivals and Traditions in Okinawa

The Naha Great Tug-of-War in October features an enormous rope that is joined by thousands of participants and attracts huge crowds. In Golden Week, the Naha Haari dragon boat races take place in the harbor, with teams rowing colorful boats.

Eisa is a folk dance performed by young people with drums to welcome ancestors during the Obon season in summer, and many towns hold their own eisa festivals. In late January and February, Okinawa has the earliest cherry blossoms in Japan, and the Nago Cherry Blossom Festival celebrates the bright pink flowers. Shuri Castle also holds a festival in autumn with a historical procession.

Best Time to Visit Okinawa

Okinawa is warm all year, but the best beach weather lasts from late April to October, with the sea warm enough to swim by May. Spring and autumn have comfortable temperatures, with fewer crowds than summer. The rainy season arrives in May and June, and typhoon season peaks between August and October.

Winter is mild, though it can be windy and cool, and it is the season for humpback whale watching around the Kerama islands from December to April. Early cherry blossoms in January and February and the Naha Marathon in December are other winter highlights.

A Sample Itinerary for Okinawa

With three days, spend the first day in Naha with a visit to Shuri Castle, Kokusai Dori and Makishi Market. On day two, rent a car and drive to the Churaumi Aquarium and Cape Manzamo. On day three, take a ferry to a Kerama island for snorkeling or a beach day before flying out.

With five days, add Miyako Island or Ishigaki for more beaches, and a day on Taketomi, a tiny island with red tile roofs and water buffalo carts. Okinawa pairs well with Kagoshima's Amami islands for an island-hopping trip, and with Fukuoka or Osaka on the way home.

For a relaxed plan, stay four nights at a beach resort on the main island and spend your days swimming, reading and enjoying local seafood. Take a half-day trip to Naha for the market and the castle. A sunset from the beach with a glass of awamori is a fine way to end the day.

Souvenirs and Local Crafts from Okinawa

Okinawan brown sugar, beni-imo purple sweet potato sweets, chinsuko cookies, awamori and Okinawa soba sets are the top edible gifts. Ryukyu glass, Tsuboya pottery, shisa lion-dog statues and bingata dyed textiles are traditional crafts, and aquarium goods are loved by children.

Practical Tips for Visiting Okinawa

Reserve a rental car early in the high season, and remember that Japanese driving rules apply, with traffic on the left. Sunscreen that is reef safe is a thoughtful choice, and many beaches have swimming areas that are marked with nets. Be aware of jellyfish season in summer.

Typhoons may cancel flights and ferries, so keep a flexible plan and consider travel insurance. Habu, a venomous snake, lives in some wild areas, so wear shoes and stay on paths. Tap water is safe to drink, and shops often close earlier on the outer islands.

Nearby Prefectures to Combine with Okinawa

Okinawa has no land neighbors, but it is a short flight from Kagoshima, whose Amami islands are close by, and from Fukuoka. Naha is also well connected to Osaka and Tokyo, so it can be added to the end of a main island trip.
