forumWhat families say
Rakuten Travel rating 4.64 out of 5 (549 reviews). Guests praise the garden open-air bath fed by the ryokan's own source flowing straight from the spring, the new-wing rooms with an open-air bath that pair a 10-tatami Japanese-style room with a low-bed space. They value it as a place where families can enjoy the onsen on their own.

Overview
Hakone Yusakaso is a 13-room onsen ryokan in Hakone-Yumoto. It has the only mixed-gender garden open-air bath in Hakone, along with the private-hire semi-open-air bath Souun no Yu, whose changing room has a diaper-changing table, and both dinner and breakfast are served as in-room dining. On the baby plan, children under 2 stay free, and a diaper set and an insulated hot-water kettle are provided as well. Families can also use the kids' corner in the lobby lounge. Only 3 rooms have an open-air bath; they are on the 4th floor, and there is no elevator.
Rooms
All 13 rooms are Japanese-style tatami rooms, and 3 of them have their own open-air bath. The basic rooms are 8 to 10 tatami mats and sleep 2 to 5 guests, while the renovated two-room layout has 10 tatami mats plus 6 tatami mats and sleeps 2 to 6, which suits larger family trips. The rooms with an open-air bath are 50 sq m special rooms with a 10-tatami Japanese-style room plus a low-bed room, sleeping 2 to 4 guests, and there are only 3 of them. The low-bed space has futons laid out on it, so there is no worry about a child rolling off and no bother of laying out and putting away futons. These rooms are on the 4th floor and there is no elevator, so if going up and down stairs is difficult, checking with the ryokan in advance is recommended.
Dining
Dinner and breakfast are served as in-room dining on every plan, so your family can take its time together in private. For parties of 5 or more, meals are set up in a private dining room instead. The children's rate for ages 7 to 11 is 70% of the adult rate, and the preschool-age rate for ages 3 to 6 is 50% of the adult rate; in both cases the menu follows the adult one. Note that the children's rate does not apply when the stay is for 1 adult and 1 child.
Baths
The garden open-air bath is the only mixed-gender one in Hakone, and since you can enter it from both the men's and the women's indoor baths, couples and families can bathe together (women may use a bathing towel). If mixed bathing does not appeal to you, there is a women-only time from 8 p.m. to 9 p.m. The private-hire bath Souun no Yu is reserved at check-in and is free for 30 minutes per group, and its changing room has a diaper-changing table and baby soap. There are 2 communal baths as well.
Family-Friendly Features
On the baby plan, children under 2 stay free; if they use futon bedding, the charge is 3,000 yen before tax. The same plan provides one set per room of a diaper set (5 Pampers diapers), a diaper-only trash bin, a Bumbo baby chair and an insulated hot-water kettle that comes in handy for night feeds (there is a charge for a second or subsequent baby). Formula and baby food are not provided, but the staff will warm baby food you bring with you. The lobby lounge also has a kids' corner. The onsen is a colorless, odorless alkaline simple spring, a type of spring water that is gentle even on a baby's skin.
