For parents, the biggest peace of mind comes from the room layout and dining arrangements. All guest rooms come with a private open-air bath, allowing you to soak with your kids as much as you want without worrying about public bath manners. They also provide private dining rooms, so we could relax and enjoy our gourmet meal even when the kids were being a bit restless.

Every room features a private open-air bath, but the infinity onsen on the top floor is a must-visit for its breathtaking views and sense of liberation. Since the hotel is part of the same group as Hakone Kowakien Yunessun, you can walk there in minutes. The kids loved the hot spring theme park and the game center, making it an ideal spot for a fun-filled family afternoon.

While rooms come with private baths, I strongly recommend visiting the public bath as well. The design is incredibly sophisticated, and the panoramic view of the landscape from the onsen is truly liberating. Before leaving, don’t forget to check the gift shop—we bought their Hinoki (Japanese cypress) soap, which is a wonderful memory of our stay.

Both the hot springs and the cuisine are absolutely flawless. You can expect a truly high-end stay where every detail is taken care of. The hospitality is exceptional, so you don’t have to worry about a thing—even when traveling with a toddler. It is a sanctuary where the high-quality service and peaceful environment live up to every expectation.

Beyond the pool, the resort is packed with family entertainment, including bowling, a game center, and an indoor sports space where I had a blast kicking a ball around with my 1.5-year-old son. Whether you drive from Tokyo or take the free shuttle bus from Odawara Station, the journey is smooth. It’s a perfect “all-in-one” destination where you don’t even need to leave the hotel to keep the kids fully entertained.

We stayed in a maisonette-style room with a spacious private open-air onsen. The level of privacy was incredible. While the room was refined and quiet, our kids had a blast treating the two floors like a playground, constantly running up and down the stairs! Most importantly, the staff provided a private dining room, which gave us huge peace of mind even when our 1.5-year-old daughter was crying.
