Introduction

Okinawa is Japan's southernmost prefecture, a chain of subtropical islands roughly 640 km southwest of Kyushu and, geographically, closer to Taipei than to Tokyo. The main island, Okinawa Hontō, holds the capital Naha and most of the prefecture's population. Recent travel guides and official tourism information consistently frame the destination less as "beach Japan" and more as its own cultural region with a history that ran parallel to, rather than inside, the rest of the country for centuries. Anyone arriving expecting a tropical extension of Tokyo or Kyoto will find a place that looks, sounds, and eats differently — and understanding why makes the trip more legible.

Not Mainland Japan: The Ryukyu Kingdom Legacy

From 1429 until 1879, Okinawa was the independent Ryukyu Kingdom, unified under King Shō Hashi with its capital at Shuri. For roughly 450 years the kingdom operated as a maritime trading hub between China, Japan, Korea, and Southeast Asia, absorbing Chinese court ceremony and craftsmanship while remaining politically distinct from mainland Japan (hondo). Japan formally annexed the kingdom in 1879. That history still shows up in the Okinawan/Uchinaaguchi language family — related to but not mutually intelligible with Japanese, and classified by UNESCO as endangered — in Ryukyu-style architecture, in Eisa drum-dance traditions, and in a cuisine built on pork and bitter melon rather than the rice-and-seafood staples of mainland Japanese cooking. This is a genuinely different region sharing a passport, not a theme-park variant of "Japan."

US Military Presence: A Fact of Modern Okinawa

Any honest guide to Okinawa has to mention the US military footprint, because visitors will see it. Okinawa hosts a large share of US forces stationed in Japan, a legacy of the 1945 Battle of Okinawa and the 27 years the islands spent under direct US administration before reverting to Japan in 1972; Kadena Air Base alone occupies roughly 80% of Kadena Town's land area. Base relocation, most visibly the long-running dispute over Marine Corps Air Station Futenma, remains a live local political issue. This is stated as background, not commentary — it shapes daily life and streetscape in central Okinawa, particularly around Chatan and Kin, more visibly than in almost any other part of Japan.

Getting There and Getting Around

Naha Airport (OKA) is the gateway, with domestic connections on ANA, JAL, Japan Transocean Air, Solaseed, and low-cost carriers Peach and Jetstar Japan, plus shorter international routes to destinations like Taipei and Seoul that shift by season — confirm current routes before booking, since Okinawa's international schedule is thinner and more volatile than Tokyo's or Osaka's. There is no Shinkansen to Okinawa; the islands are reached by air or a roughly 25-hour ferry from Kagoshima. On the ground, Okinawa's only rail line is the Yui Rail monorail, connecting Naha Airport to Shuri via 19 stations — useful within Naha, irrelevant elsewhere, where a rental car is the practical default. One quirk worth knowing before driving: Okinawa drove on the right under US administration and switched back to the left, matching the rest of Japan, only on July 30, 1978 — an event still referred to locally as "730."

One Island Among Many

"Okinawa" in casual conversation usually means Okinawa Hontō, the main island and the subject of this guide. The prefecture also includes the Kerama Islands (a short ferry from Naha, known for exceptional water clarity) and the more distant Miyako and Yaeyama island groups, including Ishigaki, which require separate flights and are effectively different trips. This guide covers Naha and the main island; treat the outer islands as their own itinerary rather than a day trip.
