forumWhat families say

Rakuten Travel rating 4.29 out of 5 (850 reviews). On the Welcome Baby plan, families praise how parents can take turns bathing thanks to the Bettei annex and the in-room open-air baths, along with touches for families such as the bouncer available to borrow. Some also note that the beds are low, so there is less risk of a fall when sleeping beside a baby. As a caution, guests point out that the second-floor rooms involve a lot of stairs and there is no elevator, so first-floor rooms are recommended for families with young children.

An onsen ryokan in Sengokuhara, Hakone. It is about a 1-minute walk from the Shinanoki Hakone Highland Hotel-mae bus stop, with 40 rooms in total across the main building and the Bettei annex. The whole property is non-smoking, and because the buildings are two stories with stairs only, a stroller has to be carried up and down.

Rooms

This ryokan bills itself as having a wide choice of rooms with an open-air bath, and many rooms in both the main building and the Bettei annex come with an onsen open-air bath. One of the themed rooms renovated in spring 2023 is the Waku Waku Kids Room for children (first floor, 41 sq m, for up to 4 guests), which has a kids' space with a mini climbing wall and an open-air bath inside the room. Other options include the pink-toned Dreamy Room, the Loft Room, and Japanese-style tatami rooms with an open-air bath and sunken-floor (horigotatsu) seating. The Bettei annex has a two-story Hanare detached room (57.6 sq m, for up to 5 guests, with a Japanese-style tatami living room with sunken-floor seating on the first floor and a bedroom with low beds on the second), as well as a Japanese-Western room with an open-air bath and a living area (38 sq m, for up to 4 guests). The family room on the second floor of the main building has an open-air bath fed by a sulfur spring.

Dining

Dinner and breakfast are served in the first-floor restaurant of the main building and of the Bettei annex respectively, in two or three seatings. In-room dining is not available. Dinner centers on sukiyaki or shabu-shabu made with top-grade Yonezawa beef, and breakfast is a Japanese set meal that includes dried fish. There is a children's menu, with a kids' plate of dishes such as Hamburg steak and fried shrimp. On the Welcome Baby plan you may bring your own baby food, and the restaurant will warm it for you; there is also a shared microwave in the building. A free-drink corner is available throughout your stay, with alcohol served, though beer and wine are not yet offered. On plans that include meals, alcoholic and soft drinks are unlimited for 70 minutes at dinner, and there is also a post-bath ice cream service.

Baths and Onsen

The communal bath is on the second floor of the main building and is open from 1 p.m. to midnight and from 5 a.m. to 10 a.m. You can enjoy two types of spring water: an open-air bath drawing on Owakudani onsen and an indoor bath of alkaline simple onsen, in tubs lined with bakuhanseki stone. Mixed bathing for children is only for those who have not yet started elementary school, so from elementary school age children bathe in the separate men's and women's baths. A baby bath and baby shampoo are available to borrow, in limited quantities. The rooms with an open-air bath in the Bettei annex use Tonosawa onsen, so a stay in the annex gives you three types of onsen in all. There is a barrel sauna on the annex grounds, available by reservation, but no one under 18 may use it, even when accompanied by a guardian. A bathing tax of 150 yen per person applies.
