Private Onsen Resort for One Couple Only

A tranquil Japanese garden welcomes you. Only one building on a large plot of land is available, a one-story style inn with a tranquil atmosphere. With its well-groomed trees, beautiful garden stones, and other features, the spacious and serene Japanese garden makes you feel as if you are visiting your own private ryokan (Japanese inn).

When you open the door, you will find a high-ceilinged space. Walls made of soft-looking Ryukyu limestone. You are instantly enveloped in an atmosphere that elegantly blends the extraordinary feeling of a resort with the relaxation of Japanese style.

Thoughts on the inn

The ultimate private space. Hakone Kairai was created to allow guests to experience the true meaning of the word.

You may feel that it is a little too large for a single guest.

However, the moment you arrive and step inside, you will be mesmerized by the spaciousness of the inn.

You will wonder if you will have the resort all to yourself. With the concept of "relaxation," sofas and chairs are placed not only inside the rooms but also around the inn.

Whether you choose to enjoy the scenery or simply stand in silence, you can enjoy a moment of tranquility, relaxing in the rich nature that stretches 360 degrees around you, with the wind and trees playing in the background.
