Sheraton Okinawa Sunmarina Resort: Rooms, Pool & Chatan Access Review

Sheraton Okinawa Sunmarina Resort: What to Know

The Sheraton Okinawa Sunmarina Resort (シェラトン沖縄サンマリーナリゾート) is a 246-room beachfront resort in Onna-son on Okinawa's west coast. According to Marriott's official site, the property features a distinctive fan-shaped design that gives every room an ocean view — a genuine architectural advantage over resorts where only premium categories face the water.

The resort sits about an hour's drive from Naha Airport and 20-30 minutes from Chatan's American Village. It is a Marriott Bonvoy property, which matters if you collect points or hold elite status. For a broader look at Okinawa's accommodation options, see our Okinawa hotel guide.

Important: The main tower is closed for renovation from December 1, 2025 through May 31, 2026. Check the official site for reopening details before booking.

Room Categories and Ocean Views

Deluxe Ocean View and Premium Options

The standard room category is the Deluxe Ocean View, approximately 344 square feet (32 sqm) with a balcony facing the East China Sea. Premium rooms offer more space at approximately 538 square feet (50 sqm). Rates average $200-400 per night depending on season — October and November are the cheapest months, August the most expensive.

Many reviewers on TripAdvisor recommend booking high-floor Deluxe Ocean View rooms specifically for unobstructed sunset views. While all rooms technically face the ocean due to the fan-shaped design, lower floors may have partial views blocked by landscaping or pool structures.

South Tower Okinawan-Style Rooms

The South Tower offers rooms with Okinawan-inspired decor — a different aesthetic from the main tower's standard resort style. These are popular with travelers who want a local touch in their accommodation. Availability and pricing for South Tower rooms may differ from the main categories.

The property was last fully renovated in 2016, with the current 2025-2026 main tower renovation being the first major update since then.

Pool, Beach, and On-Site Facilities

The resort's infinity pool is the most photographed feature — designed to create a visual connection between the pool edge and the ocean beyond. The pool is free for hotel guests. Exact pool hours were not confirmed in our research; check with the front desk on arrival.

Beach access is direct from the resort — no road crossings or shuttle buses needed. The Sunmarina beach is a sheltered bay, and the resort offers various water activities during the swimming season.

Breakfast is a buffet at ¥4,200 (~$28) per adult if not included in your room rate. Check-in is at 15:00 and check-out at 12:00 — the late checkout is generous by Japanese resort standards.

Location and Getting to American Village

The Sheraton Sunmarina is in Onna-son (恩納村), on Okinawa's central west coast. This is the main resort strip of the island, with several other major properties along the same coastline.

American Village (アメリカンビレッジ) in Chatan — a popular dining and entertainment district — is approximately 20-30 minutes south by car. Public transport between the resort and American Village is limited, so a rental car is strongly recommended if visiting Chatan's restaurants and shops is part of your plan.

From Naha Airport: The drive is approximately 52 km, taking about 1 hour via the Okinawa Expressway. No direct shuttle bus was confirmed in our research — arrange a rental car at the airport or check with the hotel about transfer options.

Parking appears to be available on-site, though we could not confirm pricing through official sources.

Value Assessment and Who This Resort Suits

Marriott Bonvoy Benefits

As a Sheraton property, the Sunmarina participates in the Marriott Bonvoy loyalty program. Elite members can expect potential room upgrades (subject to availability), late checkout, and access to Bonvoy-tier benefits. If you are accumulating Marriott points or booking with points, this property offers resort-level redemption in Okinawa.

How It Compares to Other Okinawa Resorts

The Sheraton Sunmarina occupies the mid-to-upper range of Okinawa's resort market. At $200-400 per night, it is positioned below the island's ultra-luxury properties but above basic beach hotels.

For travelers who want a city base instead, the Hyatt Regency Naha offers a completely different experience near Kokusai Street. For a family-focused beach resort comparison, see our Renaissance Okinawa resort review. For a broader comparison of what each Okinawa resort area offers, see our Okinawa resorts and attractions overview.

The Sheraton suits couples and families who want a reliable international-brand beach resort with direct ocean access, Marriott Bonvoy integration, and a location on the central west coast that puts both Naha and the northern attractions within driving range.
