Summer Vacation With Kids: 4 Ways to Pick a Family Hotel in Japan

A summer family trip raises worries long before you pick a destination. For small children, the biggest ones are the heat and the strain of getting around. Daytime outdoors saps their energy, and long transfers plus waits at popular attractions leave everyone tired for the rest of the trip. Decide which of those two you want to reduce, and your shortlist shrinks fast. There are four main ways to do it: get in the water and cool off at the sea, escape to a high-altitude plateau, stay at a hotel where the whole day can happen indoors, or base yourselves next to a theme park so you travel less.

If you choose the sea, the distance from the hotel to the beach and the depth of the pool are what matter. Grand Mercure Okinawa Cape Zanpa Resort sits right in front of Zanpa Beach. It has a 25 cm-deep Waraba pool for little ones, a lazy river that loops about 128 m, and three kinds of water slides. Because it is all-inclusive, your spending during the stay is easy to predict. Okinawa Kariyushi Beach Resort Ocean Spa has a private beach and an indoor play area called the Wonder Room. It also offers family rooms with bunk beds for children up to 40 kg, and sells baby food by age in months. In Izu, Hotel Katara Resort & Spa has an all-weather heated pool at about 33°C with a 50 cm-deep corner. There is no age limit, and children can swim with an adult as long as they wear swim diapers. At Inatori Ginsuiso, the Iso Sea Garden IKEJIRI, a rocky tide-pool play area with gentle waves, is about a 3-minute walk away, and the changing rooms have baby beds and baby baths. In Minamiboso's Shirahama Onsen area, Shirahama Ocean Resort has a round pool 8 m across and 50 cm deep. The women's large bath has a baby bed and both the men's and women's large baths have baby chairs, so getting everyone dressed after a soak goes quickly.

The highlands are for families who want to keep the heat at a distance and stretch out their time outside. Around the Fuji Five Lakes, Nasu Highlands, Karuizawa, and Yatsugatake, mornings and evenings are cooler than in the cities, so shade, lakeshores, and ranches stay comfortable for active play during the day. Pack one light jacket and you can still be outside on the chilly mornings and evenings.

If you want some days when you never leave the hotel, look for places with play areas, meals, and baths all under one roof. Grand Mercure Ise Shima Resort & Spa has a wooden kids' play space called Matoya no Mori, built with Mie Prefecture timber, and a 30 cm-deep kids' pool. A nursing room and two kinds of baby food, available from 5 months, lighten the load for families with babies. Grand Mercure Beppu Bay Resort & Spa has a picture book corner, a playroom, and a Hello Kitty room. In summer, its outdoor garden pool opens with depths from 35 cm to 110 cm, and infants can use it in swim pants. Beppu Onsen Ryochiku Bettei offers in-room dining, three private baths for family use, and an indoor play area for preschoolers, so you can plan the evening after the children fall asleep too.

If you are pairing your stay with a theme park, choose by how close you are to the park and how comfortable the room is when you return. Tokyo Disney Resort Toy Story Hotel is a 3-minute walk from Bayside Station on the Disney Resort Line, and its in-hotel baby care room is available for nursing and diaper changes. Standard checkout is a relaxed 12:00, so you won't have to rush on your last morning. Legoland Japan Hotel is a 1-minute walk to the park entrance, and every guest room follows a LEGO theme. Its indoor water play area, for hotel guests only and reservation required, includes a 25 cm-deep zone, so the fun continues indoors after a day at the park.

The number of loaner items and the ages they cover vary by hotel. For any hotel that interests you, check the verified amenities on its page, then confirm the latest conditions directly with the hotel.
