47 Travel Guide

Okinawa is Japan's southernmost prefecture, consisting of more than 160 islands stretched across roughly 1,000 kilometres of the East China Sea and Philippine Sea. Administratively it is Prefecture No. 47 in Japan's official numbering system. The main island, Okinawa-honto, hosts the prefectural capital Naha and roughly 90 percent of the population.

For centuries the archipelago formed the independent Ryukyu Kingdom, a maritime trading state with cultural ties to both China and Japan. That distinct heritage is still visible in the architecture, cuisine, performing arts, and religious practices that set Okinawa apart from the rest of Japan. The kingdom was formally annexed by Japan in 1879, placed under U.S. administration after World War II, and reverted to Japanese sovereignty in 1972.

The prefecture draws visitors with a combination of warm subtropical weather, coral-fringed beaches, dense jungle interiors, and a UNESCO-listed collection of Ryukyuan castles and sacred sites. The outer island groups — Kerama, Miyako, and Yaeyama — each have their own character and are widely regarded among the best diving destinations in East Asia.

Okinawa also carries the weight of one of the Pacific War's most devastating land battles. Sites of remembrance, including the Okinawa Prefectural Peace Memorial Museum, are an important and sobering part of visiting the prefecture.

Visas

Entry requirements depend on your nationality and intended length of stay. For current and accurate visa information, check TravelerPulse's Visas section and the official website of the Japan Immigration Services Agency before you travel.

Health

No vaccinations are specifically required for Japan, but routine immunisations should be up to date. The summer months bring high humidity and heat; sun protection and hydration are important. Jellyfish, including habu jellyfish, are present in surrounding waters from late spring through early autumn — ask locally about conditions before swimming. The habu pit viper lives on forested islands; stay on marked paths.

Typhoon season

Okinawa sits in an active typhoon corridor. The peak season runs roughly from July through September. Flights and ferries can be cancelled with short notice; travel insurance that covers weather-related disruptions is strongly advisable.

Currency and payments

Cash remains widely used, especially on outer islands and in rural areas. ATMs at Japan Post offices and 7-Eleven convenience stores reliably accept international cards. Notify your bank before departure.

By air

Naha Airport (OKA) is the main international and domestic gateway on Okinawa-honto. It receives direct flights from major Japanese cities (Tokyo Haneda, Tokyo Narita, Osaka, Fukuoka) and from several East and Southeast Asian cities. Flight time from Tokyo is approximately two and a half hours. The outer islands are served by smaller regional airports — Miyako (MMY) and Ishigaki (ISG) receive flights from Naha and some mainland Japanese cities.

By sea

Long-distance passenger ferries connect Naha to Kagoshima and Osaka on the Japanese mainland, though journey times are long (roughly 25–48 hours depending on route). Ferry travel is primarily used for cargo and by travellers with ample time. Inter-island ferries and high-speed boats link the outer island groups to Naha and to each other.

Arriving at Naha Airport

The Yui Rail monorail connects Naha Airport directly to central Naha, including Kokusai-dori and Shuri areas. Taxis and rental car desks are also available at the terminal. Verify current transport options and schedules at the airport upon arrival.

On Okinawa-honto

Public bus routes cover the main island but services can be infrequent outside Naha, and journey times are long due to traffic congestion, particularly on Route 58. Renting a car is the most practical option for exploring sites beyond the capital. An international driving permit (IDP) is required for foreign licence holders; verify requirements before departure. The Yui Rail monorail is useful within Naha city.

Outer islands

Each island group is compact enough to explore by bicycle, scooter, or small rental car. Ferries and small inter-island flights connect Miyako and Yaeyama islands. Some very small islands have no motorised vehicle rental — confirm options before you arrive.

IC cards

Suica, ICOCA, and other national IC cards can be used on the Yui Rail monorail and some buses. Confirm compatibility with local transit operators.

Ryukyuan Heritage Sites

Nine sites across the Ryukyu Islands are listed collectively as a UNESCO World Heritage property under the title 'Gusuku Sites and Related Properties of the Kingdom of Ryukyu.' Shurijo Castle (Shuri Castle) in Naha is the most visited; the main hall, which burned down in 2019, is under ongoing reconstruction — check current access conditions before visiting. Nakijin Castle ruins in the north and Katsuren Castle in the east are less crowded and offer excellent views.

Beaches and water

The Kerama Islands (Zamami, Aka, and Tokashiki), accessible by ferry from Naha, consistently rank among Japan's clearest coastal waters and are excellent for snorkelling and diving. Miyako Island's Yonaha Maehama beach is one of the longest white-sand beaches in Japan. The Yaeyama islands — Ishigaki, Iriomote, and Taketomi — combine coral reefs, mangrove rivers, and traditional village architecture.

Peace and history

• Okinawa Prefectural Peace Memorial Museum (Itoman): Documents the Battle of Okinawa (1945) through artefacts and personal accounts. Sober, thorough, and essential context for visiting the prefecture.
• Himeyuri Peace Museum (Itoman): Commemorates student nurses who died during the battle.
• Underground Navy Headquarters (Tomigusuku): A network of wartime tunnels open to visitors.

Culture and nature

• Traditional Eisa drumming and dance performances are held at community festivals throughout summer.
• Cape Hedo at the northern tip of the main island and Yanbaru forest (also UNESCO-listed as a natural heritage site) offer wildlife encounters including the endemic Okinawa rail.
• Kouri Island, connected by a long bridge, is popular for coastal scenery.

Okinawan cuisine is distinct from mainland Japanese cooking and draws on Chinese, Southeast Asian, and indigenous Ryukyuan influences. Staple ingredients include bitter melon (goya), tofu, pork, seaweed (mozuku), and purple sweet potato (beni-imo).

Dishes to try

• Goya champuru: Stir-fry of bitter melon, tofu, egg, and pork — the defining dish of Okinawan home cooking.
• Soki soba: Okinawan noodles (made from wheat, not buckwheat) served in a clear pork-based broth with braised pork ribs.
• Rafute: Slowly braised pork belly with soy sauce and awamori, rich and tender.
• Taco rice: A post-war local invention — seasoned taco-style ground beef served over white rice, originating near U.S. military bases.
• Umibudo (sea grapes): Edible seaweed with a caviar-like pop, eaten fresh with ponzu.

Drink

Awamori is Okinawa's indigenous distilled spirit, made from long-grain rice using a distinct fermentation process. Aged awamori is called kusu. Local craft beer and Okinawan citrus-based drinks (shikuwasa) are also widely available. The prefecture's traditional tea culture includes sanshin herb teas.

Kokusai-dori (International Street) in central Naha is the main tourist shopping corridor, lined with souvenir shops, department stores, and restaurants. The covered Heiwa-dori and Ichiba-hon-dori arcades branch off it and lead to the Makishi Public Market, where local seafood and produce are sold.

What to look for

• Ryukyu glass: Brightly coloured glassware made, in part, from recycled bottles — a postwar craft tradition.
• Shisa figurines: The iconic lion-dog guardian figures are the most recognisable Okinawan souvenir.
• Bingata: A traditional Ryukyuan dyed fabric with bold, colourful patterns; authentic pieces are expensive.
• Awamori: Bottles of aged kusu awamori make distinctive gifts; airport duty-free shops stock a good range.
• Beni-imo products: Purple sweet potato tarts (tarts are sold widely and are extremely popular as omiyage gifts).

Emergency numbers

In Japan, dial 110 for police and 119 for ambulance and fire. These numbers apply throughout the prefecture, including Okinawa.

Medical

Naha and the surrounding area have hospitals with emergency departments. English-language medical services are limited; carrying a translation app or medical phrasebook is advisable. Travel insurance with medical evacuation coverage is strongly recommended for visits to remote outer islands.

Connectivity

Pocket Wi-Fi rental and SIM cards for foreign visitors are available at Naha Airport. Coverage is generally good on the main island but may be limited on very small outer islands.

Electricity

Japan uses 100V / 50–60Hz with Type A plugs (two flat parallel prongs). Most visitor electronics from North America will function; European and other visitors may need a voltage adapter.

Tipping

Tipping is not practised in Japan and is not expected or encouraged.

Okinawa is generally a safe destination with low rates of violent crime. Standard precautions for personal belongings apply, particularly in busy tourist areas on Kokusai-dori.

Natural hazards

• Typhoons: The most significant safety risk for visitors. Monitor weather forecasts from Japan Meteorological Agency (jma.go.jp) and follow instructions from accommodation providers and local authorities.
• Marine hazards: Box jellyfish (habu jellyfish) can be present in nearshore waters; some beaches install nets seasonally. Ask locally before swimming in unfamiliar spots.
• Coral and sea creatures: Stonefish and other venomous species inhabit reefs; wear protective reef shoes when walking in shallow water.
• Habu snake: Venomous pit vipers are found in forested areas. Stay on marked trails, especially at dawn and dusk.

Road safety

Traffic in Japan drives on the left. If renting a car, take time to acclimatise, especially at intersections.

Okinawan culture occupies a distinct position within Japan, shaped by the Ryukyu Kingdom's centuries of relative independence and its role as a maritime crossroads. Many residents maintain a strong sense of Okinawan identity alongside their Japanese identity.

The sanshin — a three-stringed instrument similar to the Chinese sanxian — is central to traditional music and is often heard at festivals, restaurants, and cultural performances. Eisa, a form of communal drumming and dance performed during Obon season, is an important living tradition.

Religious practice blends Ryukyuan shamanism (with female spiritual practitioners called yuta and noro), Buddhist influence, and Shinto elements. Sacred grove sites called utaki are dotted across the islands; some are active spiritual sites and should be treated with respect. Sefa-utaki in Nanjo is the most important and is UNESCO-listed.

The Battle of Okinawa (April–June 1945) resulted in catastrophic civilian casualties and remains a defining part of collective memory. Visitors should approach memorial sites with appropriate seriousness. June 23 is Irei no Hi (Memorial Day), a prefectural holiday of remembrance.
