Known as ‘Japan’s tropical side’, the entire prefecture of Okinawa has a subtropical oceanic climate with an average temperature of 23°C. It consists of 160 islands extended over a vast ocean area, with 46 of these islands inhabited. Not surprisingly, there are hundred of dive sites dotted amongst the islands – not least of which is the famous Yonaguni Monument – a site that looks like the remains of a legendary city like Atlantis.

Until 1609 Okinawa was in fact a separate empire – Ryukyu– a title granted not by the Japanese Emperor, but the Chinese Emperor of the time. The Ryukyu Kingdom was a prosperous trading port connecting China and Japan with the kingdoms of Southeast Asia, continuing to trade as a prefecture of the Japanese Empire throughout Shogun rule when the rest of Japan was a ‘closed country’.

This international influence has created a culture in Okinawa that is different to mainland Japan. There is a distinct Chinese influence here that can be seen in the architecture, especially in the Sho Dynasty-era Shurijo Castle and Fukushuen Garden in the prefecture’s capital of Naha.

Okinawa is of course also known for the role played in WWII – the Battle of Okinawa was the bloodiest of the Pacific arena, claiming the lives of just under half Okinawa’s population, some 122,228 people, including, according to some reports, every male over the age of 18. You can learn something of this at the Okinawa Prefectural Museum & Art Museum in Naha as well as the old underground Navy Headquarters.

The West Coast of the main island is dotted with white sandy beaches, with diving at Maeda Point, but the more popular diving destinations are located in the islands that stretch from the main island, southwest to remote Yonaguni Island. The closest (and most popular) group of islands are the Kerama Islands, a 50-minute ferry ride from Naha, within the Kerama Shoto National Park. Of the outer islands, the most popular for diving is Ishigaki, famous for its blue coral and manta rays, and Yonaguni, for its underwater ruins.

Okinawa is located in the southern half of the Ryuku archipelago that stretches from Kyushu to Taiwan approximately 26 degrees north latitude and 127 degrees east longtitude.

Getting There

ANA have daily connecting flights to Naha, Okinawa from Tokyo and Osaka, but as Naha is an international airport, you can also fly here directly from Singapore, Taipei, Seoul, Shanghai and Hong Kong.

ANA and JAL both operate daily direct flights to Tokyo from Sydney, with Qantas and Jetstar operating daily direct flights from Melbourne and Brisbane.

There are a number of operators to choose from on the main island and Kerama Islands as well as Ishigaki, however the more remote Yonaguni has only one operator.

Where to Stay

There is a wide selection of hotels and resorts on the main and outer islands. If you’re transiting through the main island city of Naha, the Okinawa Kariyushi Urban Resort is a good choice, being only 4km from the airport and literally across the road from the Ferry wharf.

Visa and Passport Information

A 90-day visa is granted automatically on arrival to visitors from most countries; and as with most international travel nowadays, ensure that your passport is valid for at least 6 months beyond your stay.


Local currency is Japanese Yen and ATMs can be found throughout Okinawa, in Banks, Post Offices and at Lawson and Family Mart outlets, however not all ATMs accept foreign ATM/Credit Cards – ATMs have signage to indicate whether or not they accept foreign cards.

Telecommunications and Electricity

The international IDD country code for Japan is 81 and the regional code is +98. Use this handy calculator to work out how to dial a number in Okinawa. To make an international call from Okinawa, the international prefix is 010.

Tourists have access to free WiFi with over 200 hot spots at tourist attractions and facilities throughout Okinawa, and all hotels also provide fee WiFi access.

Customs and Tipping

There is no custom of tipping in Japan, and in fact, it will often be refused. Japanese people believe that you are paying for good service, so why should you pay extra? Good manners are expected however – be respectful, polite and grateful. Here’s a handy guide to tipping etiquette.

If you really want to leave a tip – do not hand over cash directly from your wallet, this is considered vulgar – place money in an envelope. But seriously – it is enough to incline your head and say “thank-you”.

Please be careful to dress modestly outside of beach areas and especially in the countryside and surrounding islands where moral and religious standards are strict.


English is not widely spoken here so it’s a good idea to learn a few Japanese phrases. Here are a few basics:

  • Good afternoon Konnichiwa
  • Good-bye Sayou nara
  • Thank-you Arigatou (arigatou gozaimas is more polite)
  • Excuse me Sumimasen
  • I’m checking out Chekku auto shimasu

  • Yes Hai
  • No Lie

Where to Eat

Island accommodation will generally include breakfast and dinner, while lunch is usually provided by your chosen dive operator. In Naha, you’re spoilt for choice in terms of dining out options. If you’re a meat-eater – make sure you try the local Okinawa Beef, which rivals Wagyu in flavour.

Naha has a wide range of top quality restaurants, everything from Shabu Shabu and Teppanyaki to steak houses, Izakaya, sushi trains and even a wonderful organic slow food buffet. The main strip for nightlife and dining out is Kokusai Street, but here are a few recommendations off the beaten track.

Kou Shabu Shabu is a great choice, where you’ll be served up large bowls of fresh vegetables and finely sliced Okinawa Beef to cook in the table-top steamer. The service here is fantastic, and food delicious.

For award-winning steak, Motobu Farm serves up Wagyu and Okinawa beef. It’s on the top floor of an unassuming-looking office block, but be sure to book – it’s always packed.

How to Get Around

Naha, the capital and main hub for Okinawa is well-serviced by a public bus system and Yui Rail. Being Japan, everything runs to timetable (to the second) so if the train timetable says it will get you from A to B in 3 min 20 sec you can be assured it will. There are also plenty of taxis (and they are cheap).

Most islands can be accessed by air transfer from Naha, via Ryuku Air Commuter (a subsidiary of JAL). There is also a ferry service to the closer islands from Naha, and to the more remote islands either from Naha or Ishigaki, depending on proximity. There are also high-speed ferry transfers from Naha to Kerama Island ports which take about half the time.

There is also a wide range of reasonably-priced guided tours of the main island.

Other Activities

It is well-worth learning something of the history and culture of Okinawa while you’re here, it’s a fascinating place with a rich (and eventful) history, renowned for its talented artisans- especially pottery, textiles and glassware.

Japanese Navy Underground Headquarters. The former navy headquarters is a rather sad place to visit, but it’s important to understand the role Okinawa played in WWII. Over half the civilian population was lost in the prolonged Battle of Okinawa. It’s a great museum and memorial to this tragic event in Okinawa’s history.
