Family-Friendly Hotels in Isawa Onsen (Hot Spring): Private Baths, Play Rooms

When you start looking for a family stay in Isawa Onsen, you find large hot spring ryokan (traditional Japanese inns) lined up side by side, and it is hard to tell which ones are genuinely easy with a baby. Isawa Onsen is a hot spring town in Fuefuki City, Yamanashi Prefecture, where the inns gather along the banks of the Fuefuki River. There is no Shinkansen (bullet train) station, but a limited express on the JR Chuo Main Line from Shinjuku Station reaches Isawa-Onsen Station with no transfers, and the town works well as a base for trips toward Mount Fuji, Lake Kawaguchi, and Kofu. This is also grape and peach country, so a trip that combines fruit picking with hot spring bathing comes together easily.

The 6 properties listed here are mostly inns with tatami-mat rooms, and 6 of them have a Japanese-style room. You can lay futons side by side on the floor, which suits families at the stage where falling out of a bed is a worry. The most thoroughly equipped for babies is Isawa Meitokan Itoyanagi, which has a baby plan reserved for families with children aged 0 to 3: it waives the facility admission fee and includes free use of a private bath, a children's futon, a diaper trash can, and even baby soap. Simple baby cribs, toilet seat inserts, and step stools can also be borrowed at no charge, but the numbers are limited, so it is safest to call ahead. Isawa Onsen Isawa View Hotel also keeps baby bathtubs, bath thermometers, and diaper-only trash cans on hand, and will let you bring baby food and warm it up. At Ooedo Onsen Monogatari Hotel Shinko, the restaurant has baby food along with children's tableware and high chairs, the large public bath's changing room has a baby changing bed, and the bathing area has a baby bathtub.

If your children are at the age where they need to move, Isawa Onsen Hotel Fuji is an easy pick. The kids play room on the first floor of the main building is reserved for children of elementary school age and younger, with a tatami-floored space holding a large slide and mini golf, and in summer the outdoor pool opens with a shallow pool for little ones. Swimsuits and float rings are not lent out, so bring your own. Chateraise Hotel Isawa has kids areas with play kitchens in two places, on the first and second floors, and dinner comes as a children's set meal for elementary schoolers and a smaller children's set for preschoolers. Hotel Shinko's lobby also has a kids space with picture books and toys plus a children's play corner with ring toss and other games, and you can feed the carp in the garden.

Under Yamanashi Prefecture's regulations, children aged 7 and over cannot use mixed-gender bathing, so if you want to soak as a whole family, it helps to secure one of the 3 inns with a private bath or the 4 with a bath in the room. Hotel Fuji's private view bath and Chateraise Hotel Isawa's private open-air bath both require a reservation and carry a fee, and Itoyanagi has a step-free family bath. Isawa Onsen Hanayagi no Sho Keizan is known for its own free-flowing hot spring source in the large public bath and its kaiseki dinners in private dining rooms, but guest rooms are smoking-permitted by default, and non-smoking rooms are limited to a few types such as those with a private open-air bath. It is also worth checking before you book that only children aged 0 to 2 can be registered as infants who need no meal or futon, and that children from age 3 through preschool are charged a facility use fee.
