Awaji Sumoto Onsen Kaigetsukan

Kaigetsukan is a baby-welcoming onsen ryokan on the seafront at Sumoto Onsen on Awaji Island, certified as a "Welcome Baby" inn by Mikihouse Child Care Research Institute. It has won the Rakuten Travel Gold Award multiple times, making it one of the most popular inns on Awaji Island.

Its standout feature is the "Baby's First Onsen Plan," created from feedback gathered from parents. The Japanese-Western room is set up as a special playroom, equipped with a crib, bouncer, Bumbo baby seat, baby futon, step stool, children's tableware, toys, picture books, and DVDs, along with safety measures such as outlet covers, door locks, and corner cushions already in place. Diapers (Pampers, up to 15 provided) and cube-type formula milk are supplied, and a nursing pillow, a dedicated diaper trash bin, and baby wipes are also on hand, greatly reducing the amount of luggage a family with a baby needs to bring.

Meals are kaiseki course cuisine featuring seafood and Awaji beef from Awaji Island, a region that has long carried Japan's food culture as a "Mikenokuni" (a region traditionally responsible for supplying food to the imperial court). With the baby plan, dinner is served as in-room dining (breakfast is a buffet at the restaurant), so families can enjoy their meal at a relaxed pace even if the children get lively, without worrying about those around them. The inn will also warm baby food and sterilize baby bottles, and the gift shop sells retort-pouch baby food and baby products.

For bathing, there is a communal bath overlooking the Kii Channel and an open-air bath in the sky, "Shiosai no Yu" (Sound of the Waves Bath), where you can soak while listening to the sound of the surf. A baby bed is set up in the communal bath's changing area, and Bumbo seats are also available to borrow, making it easier to manage the trip to the bath with a baby in tow. Some room types include family rooms with an in-room bath or a view bath, so families with babies too young to feel comfortable in the communal bath can bathe at leisure in their own room.

Just a 1-minute walk from the front of the inn is Ohama Beach, certified by the Ministry of the Environment as a "Pleasant Beach." Its shallow, calm waters make it a great choice for a child's first time swimming in the sea. In summer, Kaigetsukan also opens its own kids' pool. In addition, at the inn's own "Kaigetsu Farm," guests can enjoy a seasonal onion-harvesting experience - Awaji Island's famous specialty - with staff support.

Female staff members with childcare experience are stationed throughout the inn, and in the event of a sudden fever or similar, the inn can arrange transport to a nearby hospital or clinic (about a 5-minute drive to a pediatric hospital). Access is about 15 minutes by car from the Sumoto Interchange, or about a 5-minute walk from the Sumoto Kosoku Bus Center for highway buses, with a free shuttle available upon advance contact. Note that the baby-friendly equipment is tied to specific certified rooms and plans, so it's reassuring to confirm the plan details and applicable room type when booking.
