Okinawa, an easy few days

I'd give the first day to the city and skip the car entirely. The anchor is Shuri Castle, the red palace above Naha that was the heart of the Ryukyu Kingdom — its residence, its government and its religious centre, all at once. It's worth knowing before you go that the main hall burned in 2019 and has been rebuilt board by board (the work was expected to finish around autumn 2026, so it's worth checking where things stand when you visit) — and that the park deliberately turned the rebuilding itself into something you can watch from purpose-built decks. The old stone walls and World Heritage foundations were here long before the hall, and they're here still. From the hill I'd drift down into the city, and let the evening belong to a plain shop with a sanshin playing.

Today I'd pick up the car and let the drive be the point. The central-west coast — the Onna shore — is the Okinawa of the postcards: reef-flat water in impossible blues, headlands of raised coral, beaches that open for swimming as early as March. There's nothing here you're obliged to tick off, which is rather the freedom of it; you can pull in wherever the water looks its bluest. A natural one is Cape Manzamo, a coral cliff shaped like an elephant's trunk with the open Pacific beyond it. I'd take the coast road where I had the time and the expressway where I didn't, and aim to sleep somewhere up here — by the water, halfway to the north — so tomorrow's aquarium is a short hop rather than a marathon.

The north is where most of Okinawa's famous coastline lives, and its centre is the Churaumi Aquarium on the Motobu headland, inside Ocean Expo Park. It's built around one enormous tank — the Kuroshio Sea, named for the warm current that once made these islands a highway for ships — with whale sharks and manta rays moving behind an acrylic window over eight metres tall. I'd sit on the floor in front of it for a while; it rewards stillness more than photographs. Around it the north has its own quiet pleasures — the Bise fukugi tree avenue near the park, the bridge out to little Kouri Island — and then it's the long, sea-and-sugarcane drive back south.

The southern tip of the island, just below Naha, holds the two quietest and most moving stops — and the geography is kind, because both sit between the expressway and the airport, so you visit them on the way to your flight without ever doubling back. Sefa-utaki, in Nanjo, was the supreme sacred site of the whole kingdom — a forest of rock and shadow where the islands' highest priestess once presided, now a UNESCO World Heritage place to walk softly through. And the Peace Memorial Park at Mabuni, where the Battle of Okinawa ended in 1945, holds the Cornerstone of Peace — black granite arcs inscribed with the names of everyone who died here, of every nationality, without separating one side from the other. It's a sober, generous note to end on, and then the airport is minutes away.
