Sharing our experience in the hope others will find the information useful. We spent two nights here. Three key observations.
SERVICE
Bluntly the service was nowhere near good enough. Throughout the stay. A number of staff were clearly trying their best but it felt like we were being looked after by trainees. Three examples: on arrival we waited for 25 minutes in reception, with no one else waiting, no check outs or other check ins, with almost zero information or updates. The only contact with the sole member of staff was when she came over to us and said 'you have booked dinner for 7.30, it will be very busy, we advise you to re-book at 5.30pm'. We said no thanks, not least as it didn't suit us but also as we'd booked 7.30 many weeks before (as it turned out it was almost eerily quiet at 7.30 ... one wonders whether they were trying to get all guests seated in that single early sitting). She then returned 10 minutes later to ask if we were sure whether we wanted fresh towels every day (bear in mind we hadn't even checked in at this point). We asked to book a cab to the local (Odawara) station on departure. We were told it was 'very hard'. We were subsequently told it was taken care of, but then - over the following 6 hours, including twice at dinner that evening by two different hotel employees - we were asked, 'do you need a cab, today? tomorrow?'. These are the simple things, the small things that should be automatically removed from guests' list of worries. But they wer

“Exceptional service and facility.
A bit outside of Hakone but a great location for folks who need to stay away from the city and people. The small town/ Sengokuhara is also great - a ton of museums and good restaurants. All walking distance. ”
If you’re a foodie… this isn’t one to miss!

“A truly memorable short stay n Hakone. A great location for jumping on a bus on the Hakone loop… 15 / 20 mins (inc the walk from the hotel) and you are at the terminus for the Rope way and the Pirate boat trip across the lake.
The accommodation (with just 16 rooms) just oozes quality and tranquility with every room having its own private balcony with hot bath to soak in. Beds, whilst traditional, are so comfy!
Now… for the main event! The food…. OMG what a truly amazing experience… breakfast and dinner… and whilst super quality and beautifully (and privately) served in your own booth have a total quantity to blow even the biggest eaters!
Wonderful service and to close… I’m not sure where a couple of the ridiculous reviews have come from but they are obviously either an error or are trying it on…. Try for yourself - you won’t be disappointed.
Huge thank you to the staff for such a wonderful experience this week.”

“Beautiful room and facilities, the mealtimes are made very special by the attentive staff and the food is good. The meals are incredibly generous in size!
We found staff to be friendly and most spoke a good level of conversational English which was really helpful. The room and onsen was spotless and the beds really comfortable.
We found it easy to get around Hakone via the local bus and other modes of transport. The staff provided us with a timetable and directions to the correct stop If you have mobility issues the short walk to the bus stop is steep. My only criticism is that we were offered a taxi but then told there are no taxis and to get the bus to the station - fine by us but if we had a lot of luggage I think that would have been pretty stressful. Overall a great stay and I would definitely stay again!”

“Amazing room and hotel. Very close to the bus stop that allows for easy access to the Hakone free pass route (15 minutes away to the ropeway).
Meals were delicious (and massive!) and the staff went out their way to make us comfortable. The hot bath on the terrace was very relaxing but you also get the access to the main onsen with it's three baths. Well worth the trip!”

“A beautiful stay. The private onsens were our main draw and they did not disappoint. The room itself is huge with a large balcony. The decor is so calming. The shower is lovely. The staff and all the meals were so interesting with wonderful presentation. We loved our stay.”

“A great stay here at Kai Sengokuhara. Unfortunately it was cut short due to confusion between our agents and the hotel. That being said, the hotel were very friendly about it and apologetic.
They moved us to their sister hotel Kai Hakone for our 2nd night.
The staff, despite the lack of English did everything they could to make it up to us and I have to praise them for that!
The hotel itself is stunning, the room was beautiful with incredible views and a lovely in room onsen.
The communal onsen is nice, however not the best I’ve been to in Japan!
I think we were unprepared for the food. It’s a very Japanese hotel, whereby what you eat is fully Japanese in a small personal booth which is very bizzare. A great experience, but I wouldn’t say it’s the best meal I’ve ever had!
A great stay nonetheless. Wish it could’ve been the full 2 nights!”

“The service is exceptional. All employees are so attentive and friendly. The facilities are spot less. The room is very spacious, and private onsen in the room was very nice. ”
A friend recommend Hakone to us but we felt like we wasted our time and money by coming here and experiencing this stay.

“Not very friendly to foreigners because of lack of communication. Explaining and showing things about hotel is mandatory in a friendly way to a customer to make them feel comfortable in their stay. Overall, hotel as a building and facilities are nice but to have a better experience staff should be more friendly, informative and helpful to have their guests have a good experience at their stay. As we asked to have a taxi van to go to train station, response was not very helpful by saying that they can not guarantee to arrange big van at that time and didn’t offer any solution either. There are couple more experiences that I won’t mention but overall that made us feel uncomfortable and not very welcomed. I wouldn’t come back or advise anyone to stay at this hotel in Hakone. I am sure there are better alternatives.”

“This was the first time for my husband and I staying at a top notch Hoshino resort!
The experience of approaching and entering the building is a memorable experience by itself!
When we arrived by a taxi at the resort on Nov 14, we are greeted by the staff outside by the gate, and she helps me with my carry-on and lead us to the reception area upstairs with an impressive escalator.
The whole space inside the common areas, our assigned room and the garden outside are meticulously fantastic. As an architect myself, I could say the whole place is an amazing architectural experience which heightened your senses!
The staff is very courteous and the service is impeccable, which reflects the quality of such a resort.
It is without a doubt the best experience for such a highly rated resort!
The quietness of the place when experiencing the whole resort from the moment we arrived to incredible dinner and breakfast time, until we checked out, I believe it is due to the well planned and organized space and highest level of staff. From the moment you enter the reception area and waiting for our room to be ready, it is so quiet and peaceful.
Our apologies to only give you a 4 star, only to get your attention. The one star is taken off due to the fact that while everything else in our room is impeccably clean, the shower glass doors however was probably unintentionally forgotten to get cleaned, as those glass doors still showed water marks from previous use.

“It was an amazing stay at the Hoshino Resorts KAI Sengokuhara. If seclusion and privacy are what you are looking for, this is the place. The private outdoor onsen was incredible and so was the rest of the room. We had a nine-course pre-set dinner, which was delicious. If you are allergic to seafood, you should let them know ahead of time. The Pirate Ship cruise of Lake Ashi is only minutes away by public bus. There are a lot of restaurants and shops in that area.There was a bit of miscommunication during our checkA-our that delayed us for several minutes. This would normally be okay, but we checked out very early to catch a train and we’re almost late.”
