Enjoy Italian cuisine at a “restaurant to stay in” in Sengokuhara, Hakone

Surrounded by the Hakone Outer Rim Mountains, Hakone–Sengokuhara is a place where you can feel the breath of magnificent nature. Here stands Hiramatsu’s “restaurant to stay in,” offering exquisite cuisine and warm hospitality. Enjoy an Italian restaurant featuring fresh, seasonal ingredients delivered from the local area and beyond, along with a relaxing gourmet Accommodation where every room has free-flowing Onsen water direct from the source. The restaurant is also open for dinner to non-staying guests.

  • With more newly opened Hotels in Hakone, we have stayed at several, but after visiting Hiramatsu again for the first time in a while, we truly rediscovered how comfortable it is. My mother and I enjoyed a relaxing, unhurried stay, and we were very satisfied with both the quality and quantity of the meals. We will definitely return. Thank you again for everything.

  • I stayed here as an IKYU Diamond member. After returning from New York, I drove to Hakone myself and chose this Accommodation hoping to spend my limited time off in Japan at a relaxed pace. I will refrain from naming her, but the female staff member who assisted me showed thoughtful attention and flexible consideration, for which I am truly grateful. I will also refrain from naming him, but the male staff member who handled the payment was calm throughout, and his wording was consistently courteous and refined. He left me with a pleasant afterglow that was a perfect way to conclude my stay.In Sengokuhara, I have often stayed at other Accommodations in the past, but after spending time here this visit, I felt that the gentle atmosphere created by all of your staff is also part of what makes this Accommodation so special.I would love to return in another season. Thank you very much.
