Okinawa main island
Okinawa Hontō: regions, cities, nature and pace of life
Okinawa main island
The largest island in the Ryukyu archipelago — the heart of the ancient Ryukyu kingdom, where more than 90% of the province's population lives, and the intersection of nature, history and geopolitics.
The article dissects the coup from its geographical location, the three regions north–central–south, population and urban areas, the burden of US military bases, to the tourism economy and natural treasures.
Central island of Ryukyu
Okinawa Main Island (沖縄本島, Okinawa honto; Okinawan: Uchinā) is the largest and most populous island in the Okinawa archipelago as well as the entire Ryukyu (Nansei) range.
This used to be the center of Ryukyu kingdom (1429–1879), and today is home to the capital Naha and most American military bases. The island stretches more than 100 km north–south, surrounded by many small islands, some connected to the main island by bridge.
One island, almost an entire province
Although Okinawa Prefecture has about 160 islands (49 are inhabited), the main island alone is occupied ~53% of the area and is the residence of more than 90% in ~1.47 million people in the province.
Crossroads in the middle of the East China Sea
The main island of Okinawa is located in the middle of the East China Sea, in the southern half of the Nansei Range — far from mainland Japan but close to many major Asian cities:
~640 km from Kyushu
Located in the southwest, quite isolated from the rest of Japan.
~500 km from Taiwan
Naha is located within ~1,500 km radius of Shanghai, Taipei, Hong Kong, Seoul, Manila and even Tokyo.
Humid subtropical
Average temperature ~23°C; rainy season from early May to late June, storm season from June to November.
It is this "maritime crossroads" location that has turned Okinawa into the trading center of the Ryukyu kingdom, connecting Southeast Asia, China, Korea and Japan for many centuries.
Diverse terrain
From forested hills and limestone karst terrain in the north, to urbanized plains in the central and southern regions — the main island has a landscape that varies markedly from region to region, fringed with coral reefs.
One island, three faces
The coup is usually divided into three regions, each with a distinct personality:
| Region | Featured | Highlight |
|---|---|---|
| Northern (Yanbaru) | Subtropical forest, sparsely populated, fishing and agricultural villages | Yambaru National Park (UNESCO Heritage Site), Motobu Peninsula, Churaumi |
| Central region | Urbanization, strong American influence | Chatan/American Village, Yomitan Pottery, Okinawa City, Kadena base |
| The South | Ryukyu Political & Heritage Center | Naha Capital, Shuri Castle, Okinawa Battle Relics (WWII) |
Why divided into three?
The central part of the island is largely urbanized, while the southern tip and northern third are less populated; The northernmost part of Yanbaru is still mainly forested hills and small villages — creating a sharp contrast between the three regions.
Three faces of the island
From the primeval forests of the north, through the American-colored towns of the central region, to the ancient capital of Ryukyu in the south.
Yanbaru — primeval forest area
The most beautiful part of the main island, according to many tourists, is the north — where there is Yambaru forest, one of the largest remaining subtropical rainforests in Asia.
UNESCO natural heritage
Yambaru National Park covers the villages of Kunigami, Ōgimi, Higashi — more than 1,250 species of plants, evergreen forests, limestone mountains and mangroves.
Endemic species
Habitat of Okinawa waterfowl (Yanbaru kuina) — endemic flightless birds, along with many rare plants and animals.
Motobu & Churaumi Peninsula
Northwest peninsula with Churaumi Aquarium (Ocean Expo Park), Bise Fukugi tree line and small islands such as Kouri, Sesoko.
The north is also famous for high-end resorts hugging the coast of Onna village, Hedo cape in the far north, Hiji waterfall and Gesashi Bay mangrove forests — a paradise for nature lovers.
Far but worth it
From Naha Airport, the drive to the mouth of Yambaru forest takes more than 2 hours — that distance helps keep the north wild, quiet and fresh.
Where East and West blend
The central region is an urbanized region where traditional Okinawan culture is intertwined with a strong American influence due to a long military presence.
Chatan & American Village
Mihama American Village area with shopping centers and coastal restaurants - a bustling entertainment and dining destination.
Yomitan ceramic
The "cradle" of modern Okinawa ceramics with Yachimun pottery village, dozens of kilns and artisan workshops.
Okinawa City (Koza)
The second largest city in the province (~143,000 people), famous for its Koza area with many bars and live music.
The central region also has the Katsuren peninsula, Uruma city (gateway to small islands), and Ginowan (where many international conferences are held). This is also where one of the largest US bases in East Asia is located - Kadena.
Unique atmosphere
With a large crowd of foreigners — American military personnel and residents from many countries — the central region has a special atmosphere, where Western touches blend into a traditional Okinawan town scene.
Naha & Ryukyu heritage
Capital & ancient capital
The south is the political, economic and cultural heart of the province, where the capital is located Naha and zone Shuri — the former capital of the Ryukyu kingdom.
Naha, located on the East China Sea coast in the south of the island, is Okinawa's largest city and a commercial center since the Ryukyu period. Kokusai Street ~1.6 km long is the shopping and festival life of the city.
Shuri Castle & UNESCO heritage site
Palace of the Ryukyu kings for ~450 years, along with Shureimon gate, Tamaudun mausoleum. The main hall burned down in October 2019 and is being restored — still the best place to understand the Ryukyu kingdom.
Remnants of war
The south was where the fiercest battles of the Battle of Okinawa (1945) took place, and now has many memorials and peace relics.
The gateway of the island
Naha has an international airport, a deep-water port and the Yui Rail monorail system — Okinawa's only public railway, connecting the center with the ancient capital of Shuri.
Where more than 90% of the province's population lives
The main island is the absolute population center of the province. The Naha metropolitan area has about 800,000 people — more than half the island's population.
Naha
~311–317 thousand inhabitants. Capital city, density ~7,900 people/km² — highest in the province.
Okinawa City
~143 thousand people. The second largest, in the central region, ~20 km north of Naha.
Uruma
~128 thousand people. Gateway to the eastern small island chain.
Urasoe
~116 thousand people. Bordering Naha, in the southern urban area.
Youngest, but lowest income
Okinawa has a population youngest and fastest growing among Japanese prefectures, but has one of the lowest employment rates and average income — a unique economic paradox of the island.
Burden & motivation
Military bases and tourism — two forces that profoundly shape the life, economy and consciousness of the coup.
Geopolitical burden
Okinawa has been a strategic location for the US military since the Battle of Okinawa and the end of World War II. The island was administered by the United States until 1972 when it was returned to Japan.
Most bases are located on flat, high-value land in the central and southern urban areas. Kadena is the largest US air force base in Asia; Kadena town alone has up to 82.5% of its land as bases. Futenma located in the heart of Ginowan city (~100,000 people).
Prolonged source of stress
The concentration of bases causes noise, environmental pollution, crimes involving soldiers and hinders economic development. The plan to relocate Futenma to Henoko is still a hotly debated issue between people, the provincial and central governments.
Tourism drives the island
The coup economy is mainly based on travel and the US military presence, along with efforts to diversify into other industries in recent years.
Travel
Contributes ~15–20% of the economy; Okinawa welcomes more than 10 million visitors/year (~10.76 million in 2025).
Specialty & Industrial
Orion beer and awamori wine are symbols; highest density of eateries/bars per capita in Japan.
Subtropical agriculture
Sugar cane, pineapples and cut flowers grow well thanks to the humid subtropical climate.
Development paradox
Although gross product has increased nearly tenfold since the 1972 handover and the central government has spent tens of trillions of yen on development, Okinawa still has the lowest average income — showing that the balance between tourism growth and job quality is still unfinished.
Treasures of the sea and rocks
Surrounded by warm seas and coral reefs, the main island is a living museum of subtropical nature and Ryukyu heritage:
Churaumi Aquarium
One of the largest aquariums in the world (Motobu), recreated in 2002, ~780 species. Huge Kuroshio tank with whale sharks and manta rays.
Castle Chain (gusuku)
Shuri, Nakagusuku, Nakijin, Katsuren and Tamaudun Tomb — many are UNESCO World Heritage Sites of the Ryukyu Kingdom.
Coast & coral
Cape Manza, Cape Hedo, white sand beaches and brilliant coral reefs — famous diving, swimming and sightseeing spots.
Forest & small island
Yambaru Forest, Kouri Island, Sesoko, Bise Fukugi Treeline — diverse landscapes in just one island.
Most diverse
Few islands pack so much: primeval rain forest, 450-year-old citadel, modern town, tropical beaches and coral reefs — all in more than 100 km of length.
One island, one world
Point to remember
- Scale: ~106 km long, 1,207 km², ~53% of the area & >90% of the province's population.
- Location: middle of the East China Sea, closer to Asia than mainland Japan.
- Three regions: North (Yanbaru forest), Central (urban + America), South (Naha + heritage).
- Base: ~70% of US bases in Japan, ~14–15% of island lands.
- Economy: tourism led, youngest population but low income.
One line summary
The main island of Okinawa is special because it is both the ancient capital of a maritime kingdom, a subtropical natural paradise, and carries the greatest geopolitical weight in Japan — all coexisting on a narrow strip of land more than 100 km long.
