Ashinoyu Onsen Kinokuniya

There are two detached rooms, Hibitei and Miyamatei, one of each. Both come with an open-air bath of naturally welling sulfur spring water, an indoor bath and a terrace. Hibitei is a Japanese-style tatami room with a tatami double bed; it takes 1 to 4 guests and has child rates. Depending on the number of guests, futons may be laid out in Hibitei's main room. Miyamatei has a main room of 8 tatami mats and a second room of 10 tatami mats, plus a lounge, and is sold through the ryokan's direct booking. On room-only plans, the futons are already laid out. No information is published about crib or baby futon rentals, so if you are traveling with a baby or young child, please check in advance.

The meals served at the child rate differ from the adult meals, and if you want your child to have the same meal as adults, you need to book them as an adult. The kitchen does not change or remove specific ingredients for allergies or religious dietary restrictions. If your child has a food allergy, you will need to check and judge the food's safety yourself.

The two private-hire baths are the Edo-style Shotoku and the semi-open-air Kotan. Each costs 2,000 yen per 30-minute session, reservations are taken at check-in, and the last session is at 10:30 p.m. Depending on how many guests want to use them, your preferred time may not be available. Some plans include free use of the private-hire baths. In the detached room Hibitei, you can enjoy the naturally welling sulfur spring in your room's own open-air bath.

The bath options include a family bath: families can use the private-hire baths Shotoku and Kotan. Whether children who are not yet out of diapers can get into the tubs of the communal bath is not stated, so please check in advance. Kisshotei rooms have no air conditioning, so take care choosing your room type if you are staying with children in the hot season. Table tennis is available in the building. No information is published about a playroom or baby-item rentals.
