  • It was my first time in Hakone Gora, and I was able to relax at this quiet Accommodation surrounded by forest. From the welcome drink onward, the meals kept coming—an indulgent dinner with plenty of cheese and meat. It was a bit too much for me, but everything was delicious. Breakfast was wonderful as well, with freshly cooked rice, miso soup, and rice topped with an Onsen egg—I thoroughly enjoyed a Japanese-style breakfast for the first time in a while. It is a small-scale Accommodation with a calm atmosphere; the Room was spacious enough, and there was also an open-air bath, which made it very convenient to use. I was happy to wake up to birdsong. All of the staff were very kind and attentive—thank you very much.

  • The Room interior was stylish, and the jacuzzi was incredibly relaxing. The large public bath left my skin smooth and felt wonderful. Both dinner and breakfast were delicious, and I was very satisfied.\nI would love to stay again.
