RISONARE Atami is a Hoshino Resorts property built on a hillside above Atami, and the cobalt blue of Sagami Bay fills every room’s window. Every one of the hotel’s eight room types has an ocean view — this is not a detail reserved for premium categories but a design decision that applies across the property. The smallest room in the hotel, the Superior Japanese-Western Room, is 70 square metres. The largest, the Terrace Living Suite, is 123 square metres plus a 35-square-metre terrace. Hoshino Resorts operates under the concept “PLAY HARD,” and RISONARE Atami delivers on it across multiple dimensions: a renovated hot spring public bath with a Moon Road theme, a treehouse activity built on a 300-year-old camphor tree, a live-kitchen buffet where the fried horse mackerel prompted the reviewer to eat four servings, and sparklers provided in every room for evening use on the terrace. This is a resort hotel with a genuine point of view about what a stay should feel like, and it is executed with the consistency you expect from Hoshino Resorts.
Rooms & Amenities
The Terrace Living Suite in the Terrace Building was newly constructed in 2019 and accommodates up to six guests. The interior uses a white and blue ocean theme — a blue carpet that the reviewer described as resembling the sea, a comfortable sofa, a round table for card games, and two semi-double beds in a separate bedroom. A hidden room behind the living room functions as an additional sleeping area for larger groups. The 35-square-metre terrace extends directly from the living room and offers a panoramic view of Atami. A coffee machine and electric kettle are shelved alongside the room; cups and glasses are included. One memorable in-room detail: a lighter and sparklers are provided, along with a bucket, for evening use on the terrace — a quintessentially Japanese summer activity that most hotels do not provide as a room amenity.
The Superior Japanese-Western Room in Building B is described as the smallest room type and feels nothing like it at 70 square metres. The room uses a lighter blue palette — the designer noted that all rooms are themed on Atami’s specialities: fireworks and the sea. A tatami area with sliding door separation sits alongside two 120cm-wide beds; a HAY APEX-style floor lamp adds a design-forward note. The closet stocks loungewear in both adult and children’s sizes, a safe, and an ice bucket with glasses. A fridge stocked with drinks is provided. There is no bottled water in the rooms — a deliberate eco choice. Instead, water servers and ice makers are located on the 2nd and 10th floors of Building A and the 5th floor of the Terrace Building; tumblers are provided in every room to fill there. Yukata robes are available near the hot spring and may be worn in the restaurant and common areas throughout the property.
The bathroom in the Superior Room is fully white-tiled — clean and spacious in the washing area — with Japanese-made skincare toiletries selected for their gentle formulation. The Terrace Living Suite bathroom features a glass window with a sea view (with privacy blinds), separate from the toilet area, and two toilets — a practical consideration for a six-person room. Baby changing stations and baby beds are present at the hot spring facilities as well. Children’s amenity considerations are built into the property’s design rather than treated as an afterthought.
Onsen & Facilities
Atami Onsen Yura Yura is the hotel’s large public bath, renovated in March 2025. The theme is “Moon Road” — a reference to the path of moonlight reflected on the sea — and it is executed in midnight blue walls and ceiling with mirrors shaped after the phases of the moon. The water is a chloride spring, noted for warming the body effectively and retaining heat for an extended period after bathing. Custom hand-woven laundry baskets with individual patterns are a small detail that signals the property’s attention to material quality throughout. The facility includes a diaper changing station and baby bed, confirming that the onsen is genuinely accessible for families with infants.
The activity lounge on the 9th floor of Building A contains a parent-child climbing wall, a swinging hanging chair, pressed seaweed art activities, and a dedicated kids’ room (ball pool, kid-sized climbing wall, open 8:30-20:00, accompanied by a guardian). A sea-view workspace on the same floor offers Wi-Fi, power outlets, and a 24-hour drink server for guests who need to work during their stay. The Solano Beach Books & Cafe on the 11th floor of Building B is set on white sand with a weeping plum tree and a plum wine faucet growing from a tree trunk — the kind of installation that would not feel out of place in a design magazine. It operates as a books café from 10:00 to 21:00 and as an adults-only lounge from 21:00 to 22:30. A guest-exclusive pool with a children’s shallow section and an infant-friendly toddler pool (swim diapers permitted) is on the second floor, alongside coin laundry facilities.
The Forest Air Base Kusukusu is a treehouse activity zone built on a 300-year-old camphor tree. The treehouse itself is used for seasonal paid activities — during the March visit, an Easter party with egg tart decoration and children’s costume rental was running, with children able to borrow berets free of charge. Adjacent to the treehouse is an aerial athletic course at nine metres above ground level and 84.7 metres in length. A spa is also available on-site. Reservation and fees apply to the treehouse and athletic course; the kids’ room and pool are included with the stay.
Dining & Breakfast
Studio Buffet Mogumogu is the main dining venue and serves both dinner (additional charge) and breakfast (included with room). At dinner, the buffet runs more than 50 items across Japanese, Western, and Chinese preparations, with a live kitchen as the centrepiece. The fried horse mackerel — ajikatsu — was cooked fresh on the spot, and the reviewer described eating four of them, calling it “the most delicious thing I’ve ever had in my life.” A tuna and sashimi station, a Le Creuset curry, a raw whitebait rice bowl, and a Japanese soft serve ice cream with DIY toppings round out the dinner selection. Baby food made with safe ingredients is available for infants. All dinner venues require advance reservations.
Breakfast at Studio Buffet Mogumogu is included in the room rate and reflects the property’s commitment to local identity. A live kitchen prepares Guricha toast (made with Shizuoka green tea, the prefecture’s signature product), sea bream rice, and seafood morning ramen to order. The Mago Chazuke corner allows guests to build their own Izu Peninsula fisherman’s dish — piping hot rice topped with minced horse mackerel, bonito stock, pickled plum, and other toppings. A Danish bread corner offers more than ten varieties of original house-made bread available only at this property. The drink corner goes beyond standard orange juice and coffee with selections like apple lychee and green tea lime. Congestion levels at the buffet can be checked via QR code before visiting, allowing guests to enter without queuing. Breakfast is served 7:00 to 10:00.
The second dinner venue, Japanese Dining Hanabi, is decorated throughout with a motif referencing the Atami Seaside Fireworks Festival — table seating designed to make guests feel surrounded by fireworks, with individual firework-rod structural elements forming part of the décor. The kitchen serves creative kaiseki cuisine centred on local seafood, with golden-eye snapper and beef shabu-shabu among the courses. The reviewer noted the price is high but felt it represented good value for a full kaiseki course. The nursery service (children aged 6 months to preschool, 19:00-21:00) is provided free of charge to guests dining at Japanese Dining Hanabi, allowing parents to eat without arranging separate childcare — subject to advance reservation and capacity limits.
Location & Access
RISONARE Atami is located in Atami, Shizuoka Prefecture, approximately 40 minutes from Tokyo Station by Kodama Shinkansen. A free shuttle bus runs between Atami Station and the hotel every 30 minutes from 14:30 to 16:30 for arrivals; reservation for the return shuttle must be made at the hotel after check-in. The hotel sits on a hill above central Atami, which provides the elevated sea view that defines the property’s visual identity but means that walking into town requires effort. Atami’s year-round fireworks festival (held more than 10 times annually) is visible from the hotel terrace, and the Atami Plum Garden — one of Japan’s earliest-blooming plum blossom sites — is located nearby. The property is positioned as a destination stay rather than a base for wider sightseeing, and a two-night minimum is genuinely recommended by the hotel to make full use of the facilities.
Final Verdict
RISONARE Atami operates at the level of a full-service destination resort, and it earns that description across every category: rooms that would be considered generous by any standard, a freshly renovated hot spring public bath with a theatrical design, a breakfast buffet with live-kitchen dishes unique to the property, and a range of activities calibrated for families while remaining genuinely enjoyable for couples and solo travelers. The points worth noting before booking are real: dinner is an additional charge, most special activities involve fees, and the total cost of a stay adds up. Rates vary by season — check current prices on Agoda. But the quality at every touchpoint is consistent, and the Hoshino Resorts operational standard is visible in details as small as the hand-woven laundry baskets in the onsen and as significant as the nursery service that allows parents to enjoy a kaiseki dinner. This is one of the stronger resort options within practical range of Tokyo.
