The Best Things to Do in Okinawa

Shuri Castle sits on a hilltop in Naha and served as the royal seat of the Ryukyu Kingdom for roughly 450 years, until Japan formally annexed the kingdom in 1879. The site blends architectural DNA from both China and Japan in a way you won't see at any castle further north — vermillion-lacquered halls, dragon motifs, and a stone wall system built from Ryukyu limestone that curves rather than corners, a defensive quirk unique to the islands.

The main hall, or Seiden, burned in a 2019 fire and reconstruction has been underway since, with completion targeted around 2026. That means part of the interior is currently a construction viewing gallery rather than a finished palace room, which some travelers find disappointing and others find oddly more interesting — you can watch traditional joinery techniques being used in real time.

Entry to the castle park is roughly 400-600 yen (2024 pricing) and the grounds open around 8am, closing between 6pm and 8pm depending on season. Give it 90 minutes minimum, and go before 10am if you want the main gate, Kankaimon, without a tour bus crowd behind you.

Ask an Okinawan local where the best water is and they'll rarely say the main island's resort beaches — they'll say the Kerama Islands, a scatter of small islands about 30-40 kilometers west of Naha, famous for a shade of turquoise locals call 'Kerama Blue.' Visibility routinely runs 20-30 meters, rivaling parts of the Caribbean, and coral cover here has fared better than much of the main island's reef.

High-speed ferries leave from Tomari Port in Naha to Zamami Island, taking about 50 minutes one-way and costing roughly 2,700-3,000 yen each way (2024). A slower car ferry runs closer to two hours for about half the price. Either way, this is not a rushed half-day trip — the smart move is an overnight on Zamami, where guesthouses run from about 6,000-10,000 yen a night, so you get an early snorkel session at Furuzamami Beach before the day-tripper boats arrive around 10am.

Snorkeling gear rents for roughly 1,500-2,500 yen a day from shops near the port, and from late January through March the Kerama Channel is also one of the more reliable spots in Japan for humpback whale watching, though by April the whales have mostly moved on north.

Churaumi Aquarium sits inside Ocean Expo Park on the Motobu Peninsula in northern Okinawa, about a 90-minute drive from Naha along the Okinawa Expressway. The centerpiece Kuroshio Tank holds several whale sharks and manta rays behind acrylic panels roughly 60 centimeters thick, and standing in front of it at feeding time — typically posted around 11am and 3pm — is genuinely one of those moments that makes people go quiet.

Admission runs about 2,000-2,180 yen for adults (2024 pricing), with the aquarium open 8:30am to 6:30pm most of the year and later, to 8pm, during peak summer months. Arrive at opening if you can; by midday the walkway in front of the Kuroshio Tank gets three or four rows deep.

The wider park is worth the extra hour it takes — there's a subtropical botanical garden, a small beach, and the Emerald Sea observation deck, all included in the same grounds without an extra ticket.

Cape Manzamo, near Onna Village on Okinawa's west coast, is a limestone cliff carved by the sea into a shape locals liken to an elephant's trunk. It's free to walk out to the viewpoint, parking runs a small fee of around 500 yen, and the light is best in late afternoon when the East China Sea below turns a deep cobalt.

About 30 minutes north, the village of Bise near Churaumi Aquarium has one of Okinawa's best-preserved fukugi tree lanes — a shaded corridor of centuries-old trees planted originally as windbreaks against typhoons, running alongside traditional coral-stone walls. Bicycle rental stands near the entrance charge roughly 500 yen per hour, and it takes no more than 20 minutes to cycle the full lane, though most people linger longer than that.

Combine both in one afternoon: Manzamo around 4pm for the light, then Bise on the way to or from Churaumi the next morning, since they sit on the same coastal stretch.

Taketomi sits in the Yaeyama Islands, a separate chain roughly 430 kilometers south of Okinawa's main island — this is a genuine extension, not a day trip layered onto Naha. You fly from Naha to Ishigaki, about 60-70 minutes by air, then take a 10-15 minute ferry from Ishigaki port to Taketomi, which costs roughly 700-800 yen each way.

What you get for the trouble is a village that has kept its low red-tiled roofs, coral-lime shisa guardians, and sand-covered lanes largely intact, protected by preservation ordinances that limit new construction. Water buffalo carts still trundle tourists through the village center for about 2,000-2,500 yen for a 30-minute loop, complete with a guide playing sanshin, the three-stringed Okinawan lute.

Most visitors do Taketomi as a rushed half-day from Ishigaki. Don't — the island has a handful of small minshuku guesthouses charging around 7,000-9,000 yen a night, and staying over means you catch Kondoi Beach at sunrise with almost no one else on the sand, and the star-sand beaches on the island's north side under a genuinely dark sky.

A ten-minute walk south of Naha's main Kokusai-dori shopping street, Tsuboya has been Okinawa's ceramics quarter since kilns were consolidated here in the late 1600s under the Ryukyu Kingdom. The main lane, Yachimun-dori, is paved in old stone and lined with workshops still producing shisa — the guardian lion-dog figures you see on rooftops across the islands — alongside the heavier, glazed pottery known as arayaki.

Shops generally open around 10am and close by 6pm; a few workshops let you watch potters at the wheel, and several offer hands-on classes for roughly 3,000-5,000 yen that take about an hour and ship your finished piece home weeks later once it's been fired and glazed.

This is a good counterweight to a trip otherwise spent on beaches and reefs — it's the one entry on this list that's entirely about slowing down in a city, not a landscape.

Kouri Island connects to the main island via the Kouri Ohashi Bridge, a roughly 2-kilometer causeway over shallow turquoise water that's free to cross and takes about three minutes to drive if you don't stop — though almost everyone stops. There's a small parking area near the bridge's midpoint for photos.

Local legend holds Kouri as the birthplace of Okinawa's own Adam-and-Eve creation story, and the island still feels smaller and quieter than the Motobu Peninsula it's attached to. Tiida Beach on the island's east side has clean, shallow water good for a swim without a crowd, and a scattering of beachside cafes serve the local specialty, sea grapes (umibudo), best eaten fresh with a splash of soy and vinegar.

Kouri sits about 15-20 minutes from Churaumi Aquarium by car, which makes it an easy add-on to a northern Okinawa day rather than a destination requiring its own overnight.
