Sheraton Okinawa Sunmarina Resort シェラトン沖縄サンマリーナリゾート 沖繩太陽碼頭喜來登度假酒店

Sheraton Okinawa Sunmarina Resort is a beachfront resort hotel located on the west coast of Onna Village in central Okinawa. A 400-meter stretch of white sand and emerald-green ocean spreads out directly in front of the property, and despite its on-the-beach setting, the resort offers pools, a spa, and facilities that allow guests to enjoy a “complete resort experience” without ever leaving the grounds. The hotel consists of two buildings—the Main Tower and the South Tower—with a total of 246 guestrooms. From Naha Airport, it is roughly a one-hour drive via the Okinawa Expressway (Ishikawa IC).

The Main Tower includes around 200 rooms, such as double, twin, and maisonette types, while the South Tower houses 46 spacious guestrooms of 50㎡ or more. All rooms have balconies and primarily offer ocean views. Main Tower rooms are equipped with rainfall showers, deep soaking bathtubs, flat-screen TVs, high-speed internet, and universal power outlets. South Tower rooms—all a generous 50㎡—feature layouts with ocean-view bathrooms, open-air semi-onsen tubs, or small garden-style courtyards, offering a more upscale resort ambiance.

The interiors combine bright white tones and wood textures with Okinawan textiles and traditional patterns. On the top floor of the Main Tower, maisonette-style rooms such as the “Ocean Suite” and “Ocean Maisonette” feature Japanese-style tatami spaces and can accommodate up to five guests, making them ideal for multigenerational and family travel. South Tower rooms are known for their expansive lanais (balconies) and open-style bathrooms, appealing to guests who prefer a more private and relaxed stay.

One of the resort’s defining strengths is its extensive lineup of activities. At the beach in front of the hotel, guests can enjoy kayaking, pedal boating, stand-up paddleboarding (SUP), snorkeling, and other marine sports. The outdoor garden pool includes two waterslides—including the 83-meter “Tornado” slide—along with a shallow children’s pool. Guests can use the garden pool and slides free of charge during their stay, and the hotel also offers a “Resort Pass” that bundles access to activities such as tennis and mini-golf.

The resort’s signature attraction is the approximately 250-meter “Mega Zip,” a sea-crossing zipline that sends guests gliding from the hotel grounds out over the water. The experience of soaring above white sand and ocean is rare even within Japan, making it a popular activity for families and groups looking to create memorable moments. Usage conditions such as weight restrictions apply.

The resort’s wellness area, named “Nuchigusui,” includes an indoor heated pool, jacuzzi, gym, large communal bath, sauna, private spa treatment rooms, and rental family baths, providing an all-weather sanctuary for relaxation. The fitness gym is open 24 hours and equipped with cardio and weight-training machines for guests who wish to stay active during their resort stay.

Dining options include an all-day buffet restaurant, a course-meal restaurant, and multiple bar-lounge venues. Okinawan cuisine, creative dishes, Western meals, and grill selections are all available. The breakfast buffet often features Okinawan soba, champuru dishes, and local vegetables. At the beachside or lobby-adjacent bars, guests can enjoy tropical cocktails and light snacks while taking in sunset or nighttime views.

The resort also caters well to families, offering baby cribs, children’s pajamas, kids’ amenities, family-friendly maisonette rooms, and Japanese-Western combination rooms. Indoor and outdoor play areas and kids’ activities ensure that children have ways to stay entertained regardless of weather conditions, a major advantage when selecting a resort.

Practical amenities include complimentary Wi-Fi throughout the property, laundry service, an on-site coin laundry, a convenience store and gift shop, and rental car and taxi arrangements. Parking is available on-site for ¥1,000 per night (with a maximum cap). The surrounding Onna Village area offers cafés and diving shops, and the resort is a convenient base for sightseeing spots such as Cape Manzamo, the Blue Cave (Maeda Point), and northern destinations like Okinawa Churaumi Aquarium.

In summary, Sheraton Okinawa Sunmarina Resort is ideal for guests who want “a resort where they can enjoy the beach, pools, and activities all in one place,” as well as families or groups looking for a lively, activity-rich stay with indoor facilities available even on rainy days. With all rooms featuring ocean-view balconies, spacious South Tower accommodations, indoor and outdoor pools, large baths, a sea-crossing zipline, and a wide range of marine activities, the resort stands as a top choice along Okinawa’s west-coast beach destinations.
