Okinawa: Why Japan’s Most Tropical Island Feels Like a Different Country
By Yoshi | Japan Unveiled
The first time I visited Okinawa — I was in my late twenties, on a trip with friends who had convinced me that the beaches justified the airfare — I had the specific experience that I imagine many mainland Japanese people have on their first Okinawa visit.
I felt like I had left Japan.
Not in a negative sense. The feeling was not disorienting in the way that arriving in a genuinely foreign country can be disorienting — the language was Japanese, the infrastructure was Japanese, the convenience stores were the same convenience stores. But underneath these familiar surfaces, something was different. The light was different. The food was different. The rhythm of life was different. The relationship between people and public space was different in ways that I could feel before I could articulate.
What I was perceiving was real. Okinawa is simultaneously Japanese — fully integrated into the political, economic, and administrative structures of modern Japan — and genuinely distinct from the rest of Japan in ways that are historical, cultural, and geographic. It is a place that became part of Japan through a specific and contested historical process, that maintained distinct traditions and a distinct identity through that process, and that remains, in the experience of visiting it, somewhere that feels like a different country while technically being the same one.
The Geography: Where Okinawa Is
Okinawa Prefecture consists of approximately 160 islands in the Ryukyu Archipelago, stretching approximately 1,000 kilometres from the southwestern tip of Kyushu to the coast of Taiwan. The prefecture’s total area is smaller than any other Japanese prefecture except Kagawa, but its geographic spread — the islands are scattered across a vast area of ocean — makes it one of the most spatially dispersed.
The main island, Okinawa-honto, is where the majority of the prefecture’s population (approximately 1.4 million) lives and where the prefectural capital, Naha, is located. The outer islands — the Kerama islands, the Miyako islands, the Yaeyama islands (of which Ishigaki and Iriomote are the most visited) — are progressively more remote, more ecologically pristine, and more specific in character as you move further from the main island.
The climate is subtropical — warm, humid, with a rainy season from May to June and a typhoon season from late summer into autumn. Okinawa receives an average of approximately 2,000 millimetres of rain per year, supports coral reef ecosystems around its islands, and has an outdoor culture year-round that the cold winters of mainland Japan’s major population centres make impossible.
The History: Why Okinawa Is Not Just Japan
To understand why Okinawa feels different, you must understand that Okinawa was not always Japan.
Until 1879, what is now Okinawa Prefecture was the Ryukyu Kingdom — an independent state that had existed since the fourteenth century, with its own culture, its own language, its own royal court, its own diplomatic relationships with China and Japan, and its own specific traditions that developed through centuries of maritime trade and strategic positioning between two larger powers.
The Ryukyu Kingdom’s culture was a synthesis of Chinese, Japanese, and indigenous Ryukyuan influences, weighted differently from anything on the Japanese mainland: the shuri-jo (Shuri Castle, destroyed in World War Two and reconstructed) was the architectural centre of this culture; the bingata textile tradition, the lacquerware tradition, the sanshin (three-stringed instrument, ancestor of the mainland shamisen) tradition were its artistic achievements.
In 1879, the Meiji government incorporated the Ryukyu Kingdom into Japan as Okinawa Prefecture — an annexation that was resisted by the Ryukyuan elite and that began the process of forced cultural assimilation: the suppression of the Ryukyuan language, the replacement of Ryukyuan cultural practices with mainland Japanese ones, the integration of Okinawa into the Japanese administrative and military system.
The Battle of Okinawa in 1945 — the largest amphibious assault in the Pacific War, fought on the main island — killed approximately one-third of the civilian population: one of the most devastating episodes in Japan’s wartime history, and a specific trauma that shaped Okinawan identity and Okinawan politics in ways that persist to the present day.
After the war, Okinawa was placed under American administration — not returned to Japan — until 1972, giving Okinawa a postwar history that was distinct from the rest of Japan’s: US military rule, US cultural influence (the English-language culture, the steakhouses, the Okinawan music that incorporated American musical influences), and the specific experience of a population that was neither fully American nor fully Japanese during a critical period of cultural formation.
The reversion to Japan in 1972 returned political sovereignty but left the specific issue of American military bases — which occupy a significant proportion of Okinawa’s land area and which have been a source of consistent political tension between Okinawa, the Japanese government, and the United States — unresolved.
The Culture: What Makes Okinawa Distinct
The cultural distinctiveness of Okinawa from mainland Japan is real and specific, not a tourist marketing construction.
The language: Okinawan is not a dialect of Japanese but a separate language — Uchinaguchi — that is related to Japanese in the way that Portuguese is related to Spanish: clearly from the same family, but not mutually intelligible with standard Japanese. Uchinaguchi is classified by UNESCO as an endangered language; most younger Okinawans do not speak it fluently, having grown up speaking standard Japanese, but the language remains present in music, in certain community contexts, and in the consciousness of Okinawan identity.
The religion: Okinawa has its own indigenous religious tradition — centred on the noro (female religious officiants who serve as intermediaries between the human and spiritual worlds) and on a specific cosmology in which the islands are inhabited by a rich world of spirits and sacred sites (utaki). This tradition, while diminished, persists alongside the Buddhist and Shinto practices that were introduced from mainland Japan, creating a religious landscape specific to Okinawa.
The music: Okinawan music — characterised by the sanshin, a pentatonic scale, and a vocal style that is rhythmically and melodically distinct from mainland Japanese musical traditions — is one of the most vivid expressions of Okinawan cultural distinctiveness. The Okinawan pop genre that has emerged from this tradition — groups including BEGIN and Mongol800, the cross-genre work of artists like Rimi Natsukawa — has achieved significant mainland popularity while maintaining its specifically Okinawan character.
The food: Okinawan cuisine is distinct from mainland Japanese cuisine in ingredients, techniques, and flavour profile. The Okinawan diet has historically relied heavily on pork (pork is to Okinawans what fish is to mainland Japanese, in the local saying), goya (bitter melon), champuru (a stir-fry dish), sata andagi (Okinawan doughnuts), awamori (the distilled spirit made from long-grain indica rice, distinct from mainland Japan’s shochu), and mozuku (a specific seaweed variety). The specific combination of these ingredients and the influence of American food culture (Spam, taco rice, steakhouses) from the US occupation period produces a culinary landscape that is immediately distinct from anything on the mainland.
The Longevity: Okinawa’s Greatest Mystery
Okinawa is one of the world’s five documented Blue Zones — geographic areas with unusually high concentrations of centenarians and unusually low rates of age-related disease.
The traditional Okinawan longevity — which was, for most of the twentieth century, the highest of any prefecture in Japan — has been the subject of extensive scientific research that has identified several contributing factors: the traditional diet (high in goya, purple sweet potato, tofu, and seaweed; relatively low in overall calories), the hara hachi bu principle of eating until approximately 80% full, the specific social structures of the moai (informal mutual support groups in which group members provide each other with financial, social, and emotional support throughout their lives), and the maintained sense of ikigai (purpose) that the social and cultural integration of elderly people in Okinawan communities has historically supported.
The Okinawan longevity advantage has been eroding in younger generations, whose dietary patterns have shifted toward fast food and whose physical activity levels have changed with increasing car dependence. This generational change has been studied as a natural experiment in the effects of dietary and lifestyle change on longevity — and the results strongly suggest that the traditional lifestyle, rather than genetics, is the primary driver of the traditional advantage.
Visiting Okinawa: What to Expect
For visitors to Japan who want to experience Okinawa — which I recommend specifically as a contrast to the rest of Japan rather than as a substitute for it — the practical information.
Getting there: Naha Airport is served by multiple daily flights from Tokyo (approximately 2.5 hours), Osaka, and other major mainland airports. The Yaeyama islands and Miyako islands are served by smaller aircraft from Naha.
The main island: Naha is the cultural and commercial centre, with the reconstructed Shuri Castle, the Kokusai Dori (International Street) shopping and dining area, and the Makishi Public Market where Okinawan food culture is most directly visible. The northern part of the main island (Yanbaru) is more natural and less developed, with subtropical forest and specific endemic wildlife.
The outer islands: Ishigaki Island in the Yaeyama chain offers some of the finest beach and snorkelling environments in Japan, with coral reefs of extraordinary quality. Iriomote Island — mostly covered by subtropical jungle and accessible only by ferry from Ishigaki — is one of the most ecologically significant areas in Japan, home to the endangered Iriomote cat.
The food: eat goya champuru at a local restaurant. Drink awamori — it is strong and specific and worth understanding on its own terms. Try taco rice — the Okinawan invention of taco ingredients served over rice, a product of the American occupation period that is simultaneously absurd and excellent.
The mood: Okinawa is warmer, slower, and more relaxed than mainland Japan in ways that are cultural as well as climatic. The specific quality of Okinawan social life — more expressive, more openly warm, less governed by the restraint that characterises mainland Japanese social norms — is one of the most immediately enjoyable aspects of the visit.
It is Japan. It is not Japan. Both things are true, and both truths are interesting.
