“A beautiful property with stunning architecture and gardens, and exceptionally welcoming staff. Unfortunately, the cold”
+Beautiful architecture and garden. The staff were excellent at welcoming us on arrival and whenever we came and went.
−Unfortunately, far below our expectations for a 5-star hotel. We reported excessive humidity in our room on the first day. The staff reacted immediately, but their proposed solution did not help. The room remained freezing cold and damp, our bed linen felt wet, and all our clothes became damp. The entire hotel was cold, and even the carpets in the corridors made our socks feel damp. The room itself is tired and in need of renovation. There was dust in our room, and fx limescale across the windows throughout both the private and public onsen. This lack of attention to cleaning and maintenance is disappointing for a 5-star hotel. Virtually nobody spoke English, so even basic communication required Google Translate. I am genuinely surprised by the hotel’s 5-star rating and its place on the Top 100 Asia’s Hot Spring Hotel list. Beautiful surroundings and welcoming staff, but the overall standard was very disappointing.

+The hospitality was absolutely amazing. The staff was very friendly. The property was nice, and the private onsen was nice.
−Our room seemed to have a moisture problem. Our room smelled very strongly of mildew, the linens all felt slightly moist and the ceiling had mold / water damage

−I understand that this is a classic property, and I can certainly appreciate its history, character, and value. However, it simply wasn’t my style. I found the approach upon arrival somewhat intimidating, with staff waiting for us and directing us to a very specific parking spot rather than simply indicating the designated parking area. I also found it surprising that breakfast could not be adapted even slightly to something more Western , not even a simple option of fruit and coffee. Breakfast could also only be taken at a set time, and we had to choose between 8:00 or 8:30. Overall, I felt there were too many rules and too much formality for a place where guests are supposed to be on holiday and relaxing. The atmosphere felt almost military at times , and I know what I’m talking about, having grown up around that environment. I’m sure this style works very well for some guests, but personally, it made it difficult for me to fully relax and enjoy the stay.

+An amazing authentic Japanese style ryokan. We rented one of the rooms with an in-room Onsen and enjoyed the hot spring water.
−The beds are very firm but I believe that is a standard trait with most beds in Japan.

“Eine bedeutender Aufenthalt”
+Wir waren begeistert von der wunderbaren Tradition und Sorgfältigkeit die diese Unterkunft mit sich brachte. Ein wundervoller Ort. Sehr wertgeschätzt haben wir das unglaubliche Essen. (Rückblickend das Beste Dinner auf unserer Japanreise) An einem Mittag gingen wir spazieren und fanden ein tolles Café welches von einer herzlichen Frau betrieben wurde. In der Nähe ist außerdem der Izu Panorama Park. Im Resort selbst gibt es soviel zu entdecken. Eine kleine Ausstellung. Ruhe Räume, den Garten, das Onsen selbst, ein Café mit einer weiteren herzlichen Frau! Wie schön es doch war. Vielen Dank an das nette und diskrete Personal. Hoffentlich können wir zurückkehren und wir hoffen dass dieser Ort noch lange bestehen bleibt. /// Ich hatte vorher überlegt in einem günstigeren Ryokan zu übernachten, aber bin so froh dass wir hier waren. Alles Gute!
−Tatsächlich war unser Badezimmer von der Luftfeuchte etwas mitgenommen. Es ist auch ein älteres Anwesen. Ich muss sagen ich mochte es sehr, da ich mich in eine Zeit vor der Schnelllebigkeit der Welt zurückversetzt fühlte.
