Nanki-Shirahama Marriott Hotel 南紀白浜マリオットホテル 南紀白浜萬豪酒店

Nanki-Shirahama Marriott Hotel is an ocean-view resort set on a hill overlooking Shirarahama Beach in Shirahama, Wakayama Prefecture. Operated under the Marriott brand, the hotel sits just a few minutes’ walk from the white-sand shores of Shirarahama and about 10–15 minutes by car from major attractions such as Adventure World, Senjojiki, and Sandanbeki. Access is convenient: around 15 minutes by car from JR Shirahama Station, 20 minutes from the Nanki-Shirahama IC on the Kisei Expressway, and approximately 7 minutes by taxi from Nanki-Shirahama Airport.

The hotel features 182 guest rooms, all offering a spacious floor area of 40 sqm or more. Room categories include oceanfront rooms, rooms with private in-room hot spring baths sourced from the renowned Shirahama Onsen, as well as Japanese-style and Japanese-Western rooms. Beds are Simmons-made, and interiors are designed in a coastal-inspired palette that reflects the cobalt-blue sea and sky along with the white beaches below, creating a relaxing resort atmosphere.

Even the standard rooms exceed 40 sqm, providing plenty of space to open suitcases comfortably. Ocean-view rooms on higher floors offer sweeping views of Shirarahama Beach and the Pacific Ocean, while mountain-side rooms overlook serene greenery and the surrounding townscape. Japanese-Western rooms that accommodate up to five guests are also available, making the hotel a strong option for families and group travelers.

The property draws from Shirahama Onsen—one of Japan’s Three Oldest Hot Springs—and the onsen facilities are located on the top floor (11th floor). The large communal bath and open-air bath offer panoramic views of the Pacific Ocean. The spring quality is a “sulfur-containing sodium chloride / sodium bicarbonate hot spring,” known for benefits related to burns, wounds, skin conditions, and neuralgia. With extended operating hours (5:00–10:00 / 12:00–24:00, with slight variation by day), guests can easily enjoy a soak before or after sightseeing. Private hot spring baths are also available for families and couples seeking a more personal experience.

Selected premium rooms and suites come with their own “Onsen View Bath,” allowing guests to enjoy Shirahama Onsen directly from their in-room tub with ocean views. This is especially appreciated by guests traveling with small children or elderly family members who may find communal baths less accessible.

Dining centers around the hotel’s main restaurant, Grill & Dining G. Breakfast is offered buffet-style with a selection of Japanese and Western dishes featuring local produce from Wakayama. For dinner, guests can enjoy grilled dishes and course menus that highlight locally sourced seafood, Kumano beef, and regional ingredients—paired with ocean and sunset views from the dining area. The lobby-level Greatroom serves light meals, drinks, and cocktails in a casual setting.

Resort facilities include the large onsen baths, an outdoor pool (seasonal), a fitness center, a spa, a chapel, a shop, and a spacious lobby lounge. The outdoor pool is open during summer, offering a resort-like atmosphere with sea breezes and sunshine. The fitness center is complimentary for guests and equipped with treadmills, weight machines, and essential workout gear.

The hotel is approximately a five-minute walk from Shirarahama Beach, with a simple downhill route that leads directly to the shore. Guests can enjoy swimming and marine activities in summer, as well as beach walks and sunset viewing throughout the year. By car, major sightseeing spots such as Adventure World, Engetsu Island, Senjojiki, and Sandanbeki are within about 10–20 minutes.

The entire hotel is equipped with free Wi-Fi, making it suitable for workations and extended weekday stays. Parking for around 150 cars is available free of charge. Standard check-in time is 3:00 p.m. and check-out is 11:00 a.m., and Marriott Bonvoy member benefits are honored.
