UMITO Atami Hontei (UMITO 熱海 本邸) is a five-room hotel on a hillside above Sogaura in Atami. Every room faces the ocean, and every room has its own hot-spring bath.
On the official booking site, a CABIN with breakfast for two adults came to ¥124,600 for Tuesday, November 17, and ¥135,600 for Tuesday, December 8, taxes and fees included (checked November 10).
Dates are released a month at a time. On the 1st of each month, bookings open through the end of the sixth month, counting the current one (on January 1, for example, through June 30).
With five rooms in total, there isn't much to go around. Through November, CABIN 4 is used for the ISHITAYA sleep plan, leaving three CABINs and the ORIGIN on the regular plans. Book as soon as your dates are set.
Hontei and Bettei: two separate hotels
Hontei is the former UMITO VOYAGE ATAMI, fully renovated and renamed. Its sister property, UMITO Atami Bettei (UMITO 熱海 別邸), opened nearby in August 2025, also in Kamitaga (上多賀). They are separate hotels: Hontei is at 1027-79, Bettei at 1027-83.
The mix-up is easy to make. Bettei is the one with private-pool suites. Hontei's rooms have no pool, and there's no sauna or shared public bath on the property.
Hontei's official booking page also carries a standing note pointing you to Bettei if your dates are full, with a button to check Bettei's availability. Before you pay, make sure the hotel name says Hontei.
The old name lingers, too. Rakuten Travel lists the hotel as "UMITO ATAMI HONTEI (formerly UMITO VOYAGE ATAMI)," and the map pin linked from the official site still shows the old name.

ORIGIN or CABIN: picking a room
There are two room types. The single ORIGIN has two bedrooms; the four CABINs have one bedroom each.
ORIGIN | CABIN 1–4 | |
|---|---|---|
Number of rooms | 1 | 4 |
Layout | 2 bedrooms | 1 bedroom |
Size | 117.58 m² room + 48.50 m² terrace | 54.12–62.20 m² room (CABIN 1–2) + 16.3–20.4 m² terrace |
Capacity | 4 (up to 6 with extra beds) | 2 (up to 3 with an extra bed) |
In-room bath | Open-air bath | Semi-open-air bath |
For a couple, a CABIN is the obvious pick. ORIGIN makes sense for a family or two couples traveling together, and it's the only room where you can ask to have restaurant meals served in-room.
The booking site sells each CABIN by number. Indoor sizes are published only for CABIN 1 (62.20 m² inside, 16.3 m² terrace) and CABIN 2 (54.12 m² inside, 20.4 m² terrace), and the two cost the same on November 17.
If you'll spend most of your time inside, take CABIN 1. If the terrace is the main draw, CABIN 2 and CABIN 3 each have a 20.4 m² terrace. CABIN 4's is 16.3 m², and indoor sizes for CABIN 3 and 4 aren't published.
Private onsen: no tattoo restrictions
The spring water is classified as sodium-calcium sulfate. Because every bath is attached to a room, you never share a bath with other guests.
That also settles the tattoo question: the hotel's FAQ says there are no tattoo restrictions. For the wider rules at shared baths, see our onsen and tattoo guide.
Rates and the cancellation policy
Here's what the official booking site showed on November 10 for Tuesday, November 17. Each figure is the total for two adults, one room, one night, with taxes and fees included.
Plan | CABIN | ORIGIN |
|---|---|---|
Breakfast included | ¥124,600 | ¥262,200 |
Champagne dinner plan (dinner + breakfast; stays through Dec 31) | ¥156,000 | ¥293,600 |
Rates vary by date: the Nov 17 and Dec 8 rates quoted at the top, both Tuesdays, differ by ¥11,000. Check weekends and holidays on the booking page; on the ISHITAYA plan, Saturday, Nov 28 was priced above the weekdays.
For three or more guests, enter your headcount on the booking page to see the rate.
The Champagne dinner plan is a limited-time relaunch offer, listed in Japanese as 「ウェルカムシャンパンで乾杯。割烹ディナーと和朝食付きプラン」. A half bottle of Champagne is placed in your room's fridge, and you can ask to swap it for a local craft beer or a premium juice.
In a CABIN, that plan costs ¥31,400 more for two than breakfast only, and the gap covers dinner plus the extras. Per person, that's ¥62,300 for breakfast only and ¥78,000 with dinner.
Dinner doesn't disappear after December. Rakuten Travel also lists a regular dinner-and-breakfast plan for stays through August 31, 2027.
Accommodation tax and the hot-spring tax are already included in these rates, so neither is added at check-in. You can pay at the hotel or online. Besides the official site, the hotel takes bookings through Rakuten Travel, Ikyu and Relux.
The plan pages linked below are in Japanese. Ikyu has an English-language page for the hotel with the breakfast plan, a regular dinner-and-breakfast plan and the ISHITAYA plan, but not the Champagne dinner plan. To book that one, use the official booking site.
The standard cancellation policy in the official FAQ:
- Up to 8 days before arrival: free
- 7 days to 2 days before: 30% of the total stay price
- The day before: 80%
- On the day, or a no-show: 100%
Some plans and booking sites set their own terms, so check the policy on your booking page before you confirm.

Relaunch offers: through Nov 30 and Dec 31
Two more relaunch offers run alongside the Champagne dinner plan.
First, the ISHITAYA plan. It's a sleep-themed plan created with ISHITAYA, a Kanazawa bedding brand that's been around for over a century, and includes dinner, breakfast and a sleep consultation.
The plan is offered in CABIN 4, one room a night, for two guests of junior-high-school age or older.
It covers stays through Monday, November 30, but booking closes Friday, November 27. On November 17 it came to ¥178,000 for two, ¥22,000 more than the Champagne dinner plan's CABIN rate that night.

Second, a gift: a set of three curries developed with Kyonaka (京中), a Kyoto butcher specializing in aged meat. It's one set per room for stays through December 31, while supplies last.
The official booking site mentions the curry on the ISHITAYA and Champagne dinner plan pages, but not on the breakfast-only page. If you're booking breakfast only, check with the hotel.
The guests-only restaurant
The sea-facing restaurant seats 20, including a 10-seat counter where the cooks finish dishes in front of you. UMITO's head chef for Japanese cuisine, Ryuichi Inoue, oversees the menu.
Dinner is a kappo course (counter-style Japanese cooking) featuring Shizuoka ingredients, with dishes such as sashimi, sushi, a meat course and clay-pot rice. You pick a start time between 6:00 and 8:00 p.m.
Breakfast is Japanese, with golden-eye snapper (kinmedai) and tororo-jiru (grated yam soup), served at 8:00 or 9:00 a.m.
The restaurant is for hotel guests only, with no meal-only bookings, and its page says both dinner and breakfast must be reserved by 11:00 a.m. three days ahead. The dress code is smart casual; room wear and the hotel's sandals aren't allowed.
House rules to know before booking
- No pets (guide and service dogs excepted).
- Children of elementary-school age or younger can share a bed with an adult, one child per adult.
- On dinner plans, check-in closes at 8:00 p.m. (10:00 p.m. on the breakfast plan).
- The hotel isn't set up for barrier-free access. If you use a wheelchair, contact the hotel in advance.
Getting there from Atami Station
It's about 13 minutes by car or taxi from Atami Station. There's no shuttle, but the hotel can call a taxi for you.
Searching by hotel name can bring up Bettei or the old name, so enter the full address (静岡県熱海市上多賀1027-79) into your navigation app instead.
By bus, take a Tokai Bus (東海バス) from bay 6 at the Atami Station bus terminal toward Ajiro (網代) and get off at Akao Forest (アカオフォレスト); the hotel is a 3-minute walk from the stop. Times are on the Tokai Bus timetable.
There are five parking spaces, free for guests. Rakuten Travel says they're first come, first served, so if you're driving, ask the hotel about space ahead of time.
Atami holds fireworks over the bay several times a year, and the dates are in our Atami fireworks guide.
