Family Beach Holiday in Okinawa

When people asked about our Japan trip, the reaction to “we went to Okinawa too” was almost always surprise. Most family itineraries stick to Tokyo, Kyoto, and Osaka — and those are all brilliant — but Okinawa gave us something completely different. Subtropical beaches, a world-class aquarium, and a culture that feels distinct from the mainland. It was the beach holiday our kids needed after two weeks of temples and trains, and we’d do it again in a heartbeat.

Getting There

Okinawa is about 2.5 hours by flight from Tokyo (Haneda or Narita). There are also direct flights from Osaka, Nagoya, and other major cities. We flew from Haneda with ANA and tickets were around ¥12,000-¥18,000 per person each way depending on when you book. Naha Airport is the main hub and it’s well-connected to the city by monorail.

We spent four nights in Okinawa, which was enough to cover the main island highlights without rushing. Three nights would also work if you’re short on time.

Churaumi Aquarium

This was the first thing our kids asked to do, and it didn’t disappoint. Churaumi Aquarium sits on the northwest coast of the main island, about 90 minutes’ drive from Naha, and its centrepiece is the Kuroshio Sea tank — one of the largest aquarium tanks in the world. Watching whale sharks and manta rays glide past the enormous viewing window kept our kids (and us) staring for a solid 20 minutes.

Admission is ¥2,180 for adults, ¥1,510 for high schoolers, ¥710 for elementary and middle school students, and free for under-sixes. After 4pm, discounted tickets are available at ¥1,510 for adults. The aquarium is part of the larger Ocean Expo Park, which also has a free beach, a planetarium, and a manatee exhibit. We spent half a day here easily.

There’s a cafe overlooking the main tank where you can eat lunch while watching the whale sharks swim past. A curry rice set was about ¥1,000. Not gourmet food, but the view makes up for it.

Beaches

The beaches in Okinawa are on another level compared to mainland Japan. The water is clear, warm, and that impossible turquoise colour you see in photos. Our favourites were Manza Beach (great for snorkelling, beach entry ¥500) and Nirai Beach, which felt quieter and had gentle waves perfect for little ones.

Most resort beaches have equipment rental — snorkel sets run about ¥1,000-¥2,000 per day, and kayaks around ¥3,000 per hour. We snorkelled at Manza and even in shallow water the kids spotted parrotfish and sea cucumbers.

One important warning: box jellyfish (habu kurage) are present from June to September. The main swimming beaches have netted-off areas during this period, and you should stick within those nets. We visited in June and the nets were up but the water was still lovely and warm. Outside of jellyfish season, you can swim more freely.

Shuri Castle

Shuri Castle in Naha was the royal palace of the Ryukyu Kingdom, which ruled Okinawa for centuries before it became part of Japan. The castle was badly damaged by fire in 2019, and when we visited, reconstruction was still underway. But the grounds, walls, and some of the gates are open, and there’s something interesting about watching a centuries-old building being rebuilt using traditional methods.

Entry to the paid areas is ¥400 for adults and ¥160 for children. Even if the main hall isn’t fully rebuilt when you visit, the elevated position gives great views over Naha. Our kids were more interested in running along the wide castle walls than the history, but that’s fine.

American Village

On the central west coast, American Village (Mihama) is a shopping and entertainment district with a distinctly American flavour — a remnant of the significant US military presence in Okinawa. Think colourful murals, a Ferris wheel, arcades, and restaurants serving everything from tacos to steak alongside Okinawan food.

It’s not culturally deep, but our kids loved the arcades and the ice cream shops, and the sunset from the nearby Sunset Beach was one of the best we saw in Japan. We spent an evening here after a beach day and it was a fun, low-key way to end the afternoon.

Okinawan Food

Okinawan cuisine is genuinely different from mainland Japanese food. Okinawan soba is made with wheat flour noodles (not buckwheat like mainland soba) in a pork broth, often topped with stewed pork belly or spare ribs. A bowl costs around ¥700-¥900 and our kids slurped it up happily.

Other dishes to try: goya champuru (stir-fried bitter melon with tofu, egg, and pork — the adults liked it, the kids did not), taco rice (exactly what it sounds like — taco fillings over rice, very kid-friendly, about ¥600), and purple sweet potato tarts (¥200 each, sold everywhere as souvenirs and snacks). For more on feeding kids in Japan, Okinawa is one of the easier regions because the flavours tend to be milder and less fishy than some mainland cuisine.

Rental Car Needed

Unlike mainland Japan where trains take you everywhere, Okinawa really requires a car. Public transport exists but it’s limited, and the main sights are spread across the island. We rented a compact car from a company near Naha Airport for about ¥5,000 per day including insurance. Roads are well-maintained, signage includes English, and driving is on the left like the rest of Japan.

Book your car in advance, especially during summer and Golden Week. Most rental companies provide child seats for free or a small fee (ours was included). Parking is free or cheap at most attractions. One tip: highways in Okinawa have tolls, but the amounts are small (usually ¥100-¥500 per section).

Best Time to Visit

Okinawa’s subtropical climate means it’s warm much earlier and later than the mainland. The rainy season (tsuyu) typically runs from mid-May to mid-June, and it can rain heavily. July and August are hot and humid with the jellyfish risk. We’d recommend April to early May or October to November for the best balance of good weather, swimmable water, and manageable crowds.

We went in mid-June (right at the end of rainy season) and had a mix of downpours and sunny spells. The aquarium and Shuri Castle gave us rainy-day options, and when the sun came out the beaches were stunning.

If you’re adding Okinawa to a wider Japan itinerary, it works best as a bookend — either at the start to ease into the trip with beach time, or at the end as a wind-down before flying home. Either way, it showed our kids a side of Japan they didn’t expect, and that’s exactly the kind of thing that makes a trip memorable.
