Overview
Uomisaki Hotel gives you a coastal hot spring stay directly opposite Atami Port. From the upper floors, baths, and dining rooms, you can look across Atami Bay, the surrounding hills, and the lights of the city after dark.
The hotel has 79 rooms and suits you when you want an easygoing stay with buffet dining, included drinks at dinner, natural hot springs, and free entertainment. Atami’s waterfront, ferry terminal, historic buildings, and sightseeing spots are also within easy reach.
You can spend the afternoon exploring the town, return for a rooftop bath overlooking the bay, and finish your evening with a buffet, karaoke, table tennis, or manga.
Accommodation
You can choose from Japanese rooms and Western rooms in the Main and South Wings. Room size, floor, view, and bathroom arrangement depend on the category you book.
Japanese rooms range from compact six-tatami layouts to rooms with as many as 20 tatami mats. You sit around a low table during the day and sleep on futons prepared on the floor at night. Larger two-room layouts give you more space when you travel with family or friends.
Western rooms include twin and triple categories for you when you prefer beds. Selected upper-floor rooms face the ocean and give you broader views across Atami Bay, while lower-priced categories may have restricted or no sea views.
The largest top-floor special room combines a 24-tatami Japanese area with a twin bedroom. It accommodates groups of up to ten people and looks across the sea and Atami’s night skyline. Reaching this room and some other areas requires stairs.
Your room includes a refrigerator, safe, hair dryer, towels, bath towels, yukata, toothbrushes, shampoo, conditioner, body soap, razor, comb, and brush. Free Wi-Fi is available in all rooms. Pets cannot stay at the hotel.
Dining
Dinner is served in an ocean-facing buffet venue on the upper floor of the South Wing. Large windows look across Atami Bay while you choose from around 40 Japanese, Western, and Chinese dishes.
The buffet changes with the season and may include sashimi, sushi, grilled dishes, fried food, noodles, curry, vegetables, salads, rice dishes, fruit, and desserts. Limited-time fairs add regional seafood and seasonal recipes to the regular selection.
Your dinner session lasts 90 minutes. Alcoholic and non-alcoholic drinks are included, allowing you to enjoy draft beer, sake, shochu, whisky, soft drinks, and other available choices without purchasing a separate drinks package. Your starting time depends on how busy the hotel is and is arranged when you arrive.
You can add a special dish when you want a more generous meal. Choices may include Shizuoka wagyu steak, abalone grilled with butter, or a whole simmered kinmedai. Advance ordering is recommended because quantities may be limited.
Breakfast is also served as a buffet and includes Japanese and Western food. You can choose rice, bread, fish, eggs, vegetables, side dishes, soup, and drinks according to your appetite. Breakfast normally runs from 7:30 AM to 9:00 AM, with a 60-minute dining period.
Onsen and Wellness
Uomisaki Hotel uses natural Atami Onsen water in its shared indoor and open-air baths. Both bathing areas overlook the sea, but they sit in different parts of the property.
The Main Wing’s eighth-floor observation baths are Taikan no Yu for men and Sazanami no Yu for women. Wide windows look across Atami Port and the bay, allowing you to enjoy the coastal view while remaining indoors.
The South Wing’s eleventh-floor rooftop bathing area includes Hoshi no Yu for men and Tsuki no Yu for women. These open-air baths look across the city lights and sea and include popular individual pot baths. A sauna is also available in the rooftop bathing area.
You need to use stairs to reach the open-air baths, which may be difficult when you have limited mobility. The indoor baths provide an easier option while still giving you a wide sea view.
The indoor baths use a calcium-sodium chloride spring classified as hypertonic, neutral, and high-temperature. The open-air baths use a calcium-sodium chloride spring classified as hypertonic, mildly alkaline, and high-temperature. Salt-rich water helps your body retain warmth after you leave the bath.
Traditional bathing indications include relief from joint discomfort, neuralgia, sensitivity to cold, tiredness, frozen shoulder, and minor cuts. Treat these as established onsen indications rather than medical treatment.
The indoor and open-air baths normally open from 3:00 PM to midnight and again from 5:00 AM to 10:00 AM. They close overnight between midnight and 5:00 AM for safety and maintenance.
Guests with Tattoos
If you have tattoos, you cannot use the shared indoor baths, rooftop open-air baths, or sauna. Uomisaki Hotel does not provide a reservable private onsen or family bath, so there is no private alternative for enjoying the natural hot spring water.
Facilities
Private karaoke rooms open from 1:00 PM to 10:00 PM and are free to use for one hour. You need to reserve your session at reception after 1:00 PM on the day of your stay. Advance reservations are not accepted, and popular times may fill quickly.
Free table tennis is available in the Main Wing from 1:00 PM to 10:00 PM without a reservation. The nearby game corner operates during similar hours and includes paid arcade machines.
The Main Wing’s eighth-floor manga corner holds around 1,700 titles and stays open 24 hours. You can read there free of charge, although books must remain inside the designated area.
The South Wing shop opens from 8:00 AM to 8:00 PM and sells Atami products, sweets, drinks, and travel souvenirs. You can also choose a yukata from the hotel’s yukata corner after arrival.
Four rental bicycles are available free of charge between 9:00 AM and 4:00 PM. Each session lasts up to one hour, giving you time for a short ride along the waterfront or through nearby streets. Go and shogi sets can also be borrowed for use in your room.
Activities
Atami Port is around five minutes away on foot. From here, you can board a ferry to Hatsushima, with the crossing taking about 30 minutes. The island offers coastal walks, fishing, diving, food stalls, and views back toward the Izu Peninsula.
Kiunkaku is around ten minutes away on foot. The former villa combines Japanese architecture with European and Asian decorative details and includes a landscaped garden.
You can reach Kinomiya Shrine in around five minutes by car and MOA Museum of Art in around ten minutes. Atami Castle, the ropeway, waterfront parks, shopping streets, and cafés also fit easily into a short stay.
The Atami Marine Fireworks Festival takes place on selected dates throughout the year. The hotel’s coastal position and upper floors provide strong views across the bay when an event is running.
Inside the hotel, you can create a simple evening around an onsen soak, buffet dinner, karaoke, table tennis, manga, and a walk beside the harbour.
