Quick Facts

Primary airport: Naha Airport (OKA)
Typical transfer: 15 minutes drive or 15 minutes Yui Rail ride to central Naha
Entry requirement: Japan operates a visa waiver program for many nationalities, allowing short stays of up to 90 days for tourism and business without a visa.
Getting around: Within Naha, the Okinawa Urban Monorail, known as Yui Rail, runs from the airport through central Naha to Shuri and on to Urasoe, making it easy to reach many hotels and the castle area without a car.

Getting There

Most international visitors connect through Tokyo, Osaka, or other Japanese hubs before flying to Naha Airport (OKA), which handles both domestic and regional international flights and sits only a short monorail ride from central Naha. From Naha you can take ferries from Tomari Port to the Kerama Islands or hop short domestic flights to Miyako (MMY), Ishigaki (ISG), and Yonaguni (OGN) to reach other parts of Okinawa Prefecture. Typhoons and strong winds can disrupt both flights and ships, sometimes for several days, so it is worth keeping your final dive day away from your departure flight and allowing buffer in multi island itineraries.

OKA • ROAH

4 km • 15 minutes drive or 15 minutes Yui Rail ride to central Naha

Naha Airport is Okinawa's main gateway, with a single complex divided into domestic and international areas and dense connections to major Japanese cities plus nearby islands. It sits just west of central Naha and connects directly to Yui Rail, taxis, and rental car lots.

Getting Around

Within Naha, the Okinawa Urban Monorail, known as Yui Rail, runs from the airport through central Naha to Shuri and on to Urasoe, making it easy to reach many hotels and the castle area without a car. Intercity buses run along the main Route 58 corridor, but service to remote beaches and dive sites can be limited. Many visitors rent cars to explore Onna, Motobu, Sesoko, and the Yanbaru region at their own pace. Taxis are widely available around Naha and the resort areas, and some dive shops provide hotel transfers for boat trips.

Entry Requirements

Japan operates a visa waiver program for many nationalities, allowing short stays of up to 90 days for tourism and business without a visa. Requirements change periodically, so always check the latest information from your local Japanese embassy or the Ministry of Foreign Affairs before traveling. Your passport should be valid for the duration of your stay, and you may be asked to show onward travel and accommodation details on arrival. As with the rest of Japan, Okinawa enforces strict customs rules on certain foods, plants, and animal products.

Gear Logistics Checklist

Okinawa's dive infrastructure is well developed. Most operators supply tanks and weights and can rent full sets of gear, including 5 mm suits in winter. Verify in advance whether your chosen shop stocks sizes that work for you and whether prices include Kerama environmental levies and port fees. If you travel with your own kit, consider packing a 3 mm full suit for late spring to autumn and a 5 mm with hooded vest for winter, plus booties for shore entries, SMBs, and a dive computer. Nitrox is available with some operators but not universal. Securely pack regulators and computers in carry on luggage and check airline baggage allowances for domestic flights, as some low cost carriers charge extra for large bags. Rinse tanks at dive shops and hotels are common along the main island dive belt, and many accommodations catering to divers offer drying areas and gear storage. On remote islands, expect simpler facilities and consider bringing spares like mask straps, o rings, and basic tools.

Practicalities

Currency

Japanese Yen (JPY)

Japanese Yen is the only legal tender, with most hotels, larger restaurants, and dive shops accepting major credit cards. Smaller guesthouses, local eateries, and some rural shops still prefer cash, so carry a reasonable amount of yen, especially when heading to outer islands.

ATMs are available at convenience stores, post offices, and banks in Naha, resort areas, and larger towns, but can be scarce on small islands. International cards generally work at Japan Post and major convenience chains; withdraw ahead of time before traveling to Zamami, Tokashiki, or remote villages.

Electricity

100V • 50/60Hz • A, B

Okinawa uses the same electrical system as the rest of Japan: 100V with Type A and B flat pin plugs. Most modern chargers for phones, cameras, and laptops accept 100 to 240V and only need a plug adapter. Heavy duty appliances designed for 220 to 240V only should not be used without a suitable transformer.

Communications

Mobile coverage around Naha, Onna, Chatan, Motobu, and most main island coastlines is generally strong, with 4G and growing 5G service. Coverage can drop in remote bays, forested valleys, or offshore, especially on smaller islands. Prepaid eSIMs and physical SIMs are widely available, and many hotels, cafes, and dive shops provide free Wi Fi. For typhoon season, consider downloading offline maps and saving important contacts on your device.

Language

Japanese is the primary language, with Okinawan and other Ryukyuan languages also spoken informally among locals. English is common in larger hotels, many dive shops, and tourism desks, but less so in small family run restaurants or rural areas. The Okinawa Multilingual Contact Center offers phone and chat support in several languages for visitors who need help with transport or emergencies. Learning a few basic Japanese phrases and using translation apps will make day to day interactions smoother.

Insurance

Comprehensive travel insurance that covers medical care, trip interruption, and weather related delays is highly recommended, particularly during typhoon season. Divers should add dedicated dive coverage, such as policies offered through DAN or equivalent providers, which include emergency evacuation and hyperbaric treatment. Check policy wording for maximum depths, gas mixes, and exclusions relating to technical or cave diving.

Packing list

For most of the year, light, breathable clothing, sandals, and a hat will see you through topside activities, with a light jacket for cooler evenings in winter. For diving and snorkeling, bring at least a 3 mm full suit (or rent locally) and consider a 5 mm suit and hooded vest for January to March. Include booties for rocky shore entries, a reef safe sunscreen, polarized sunglasses, motion sickness remedies, and a small dry bag for boat days. In typhoon season, pack a compact umbrella or lightweight rain jacket and waterproof protection for electronics.
