Okinawa is closer to Taipei than to Tokyo, and the map explains the rest.
Naha lies about 628 kilometres from Taipei and about 1,554 from Tokyo. The prefecture is 160 islands scattered across a thousand kilometres of sea, with 2,281 square kilometres of land in total and no point higher than 526 metres. Almost everything that surprises a first-time visitor — the food, the drink, the music, the colour of the roof tiles — follows from that position.
Almost everyone who arrives in Okinawa for the first time is carrying the wrong map. They picture a tropical island south of Japan, more or less Kyoto with a beach. What they find is something else: a very long archipelago, almost without height, laid out between the East China Sea and the Pacific, whose western tip is visible from Taiwan on a clear day.
01 A thousand kilometres east to west
The prefecture ranks 44th of 47 by area: 2,281 square kilometres, less than a mid-sized European province. But those kilometres are not in one piece. They are spread over 160 islands — 49 inhabited — that stretch some 1,000 kilometres east to west. Imagine a single region running from Lisbon to Marseille with dry land on only eleven of those kilometres.
The main island concentrates the imbalance: 1,207 square kilometres, a little over half of the whole territory, and around nine in ten of the prefecture's inhabitants. It runs 106 kilometres north to south and in many stretches is barely eleven wide. From inland you can usually see the sea on both sides.
The western end is Yonaguni: 28.88 square kilometres, about 1,700 residents and 107.4 kilometres of separation from Taiwan at the closest point. On clear days the island can be made out with the naked eye from the Taiwanese mountains. That figure is not trivia. It is the key to everything that follows.
02 A kingdom that lived off passing trade
An archipelago with little land, little height and no large rivers cannot live off what it grows. It can live off what passes in front of it. Between 1429 and 1879 these islands operated as a trading kingdom, Ryukyu, whose wealth came not from its fields but from moving goods between China, Japan, Korea and Southeast Asia.
You notice it before you understand why. The historic architecture of Shuri has neither the bare timber nor the grey tile of mainland Japan: it has red lacquer, reddish tiles and a decorative vocabulary that reads better looking south and west. Most visitors' first reaction is that it does not look Japanese. The reaction is correct and the reason is geographic.
03 The pantry arrived by boat
The cleanest case is awamori, the local spirit. It is not made with short-grain Japanese rice but with long-grain indica rice imported from Thailand, fermented with a black mould, and the distilling technique reached the islands from Siam in the fifteenth century. It is the oldest distilled drink in Japan, and its recipe is an inventory of sea routes.
Food works the same way, sometimes more loudly. The most popular dish in the islands is called soba and contains not a gram of buckwheat: thick, pale wheat-flour noodles in a broth of pork and dried bonito. In the 1970s that contradiction reached an office in Tokyo and the name had to be negotiated. But that story deserves telling separately.
Pork, for its part, is not a recent indulgence. On land without pasture or room for large livestock, the animal that fits in a yard and eats the scraps becomes the base of the kitchen. None of this is folklore. It is arithmetic of surface area.
04 Snakeskin on a Japanese instrument
The sanshin is the household instrument: three strings, long neck, small round body. What catches the eye is the soundboard. Not wood, not cowhide, but snakeskin — often synthetic today — a raw material that does not exist here in quantity and that arrived, like the awamori rice, by sea from the south.
The detail matters because the sanshin later travelled north, where it became the shamisen — the instrument that sounds like classical Japan to half the world. The direction of travel is usually told backwards. No provincial version of Japanese music arrived here. Part of Japanese music left from here.
05 The one Japan where it does not snow
Naha averages 23.3 degrees a year and 2,161 millimetres of rain. The January mean is 17.3 degrees — higher than the average January high in Madrid. At sea level it does not snow; the single record of sleet on the main island was logged in January 2016 and made the national news.
The vegetation goes further than the thermometer. The far southwestern islands have mangrove, coral reef and an endemic wildcat, the Iriomote cat, found nowhere else in the country. A Japanese traveller from Aomori landing on Ishigaki is more than 2,500 kilometres from home and in a biome they do not recognise.
06 What this changes for the traveller
The first consequence is that going to Okinawa means nothing specific. Naha and Ishigaki are 411 kilometres and one flight apart; Ishigaki to Yonaguni is another hop. There is no road linking the islands and no train running through them. Each group is a separate decision, and anyone trying to see them all in a week spends the week in airports.
The second is that the archipelago rewards staying put. With so little surface and so little height, no island needs to be covered end to end: the interest is not in distance but in returning to the same reef two days running and noticing the tide has changed. It is the opposite of the classic Japanese trip of bullet trains and a list of cities.
The third is about expectation. Anyone coming for Japan will find Japan, but with the accent shifted: the rice in the still is Thai, the tile is red, the national instrument is played here in its oldest form, and the mental map has to be turned almost ninety degrees. What stays with you is not a beach postcard. It is the useful discomfort of having been somewhere that does not fit where you had filed it.
