Kansai Hotels With Pools for Kids: Indoor, Outdoor and Diaper-Friendly
Can you swim in winter, or only in summer? Are kids in diapers allowed? Is there a water slide? Compare Kansai hotels using the facility data we have collected.
14 areas ยท 369 hotels (total listings across these areas)
When you look for a hotel with a pool in Kansai (the region around Osaka, Kyoto, and Kobe), it's easy to wonder, "Is the pool only open in summer?" and "Can my child swim if they're not potty trained yet?" Many outdoor garden pools are open only in summer, so a fall or winter trip can mean a closed pool. Rules on swim diapers also differ from hotel to hotel, and some families find this out only after booking. The quickest way to narrow down Kansai hotels with kids is to check two things first: whether the pool is open year-round or only in summer, and whether children in diapers are allowed in.
Hotels with an indoor pool that is open all year include Spaworld Hotel & Resort, Kobe Arima Onsen Motoyu Ryusenkaku, Shirahama Coganoi Resort & Spa, Yumekaiyu Awajishima, Hotel Okura Kobe, and Kobe Portopia Hotel. Spaworld has both a kids' pool and water slides, and Ryusenkaku has a 4 m x 10 m heated indoor pool that guests can use as often as they like during their stay. The pools at Coganoi and Yumekaiyu are free for hotel guests. The indoor pool at Hotel Okura Kobe is for ages 4 and up, and Kobe Portopia Hotel has no children's pool, so neither suits very young kids.
For outdoor pools in summer, family-friendly choices include Hotel New Awaji and Grand Mercure Awaji Island on Awaji Island, Shiraraso Grand Hotel and Yanagiya in Nanki-Shirahama, and Biwako Hotel on Lake Biwa. Of the Kansai hotels we list, 19 have a pool that kids in diapers can use, and 6 have a water slide.
None of the Kansai hotels we list yet offers a private pool that your family can reserve for itself. For that kind of stay, see our private pool collection, which focuses mainly on Okinawa.

Lake Biwa: Spend the Summer at a Lakeside Garden Pool

Biwako Hotel has a pool divided into depths of 0.6 m and 1.2 m. Lake Biwa Otsu Prince Hotel has a pool about 90 m long with a separate children's pool that is 30 cm deep.
Awaji Island: Compare Shallow Pools and Pools With Slides
Awaji Island has hotels with summer outdoor pools, but also ones with year-round indoor pools or pools with slides. Which hotel works best depends on when you travel.
Awaji Island
Yumekaiyu has a shallow, heated indoor pool that is free for guests and open all year. Hotel New Awaji has a pool with a shallow slide for small children.
Tips for traveling with kids
- checkMany outdoor pools are open in summer only, so check first that your travel dates fall within the open season. That way you avoid arriving to find the pool closed.
- checkMost hotels ask kids in diapers to wear a swimsuit over swim diapers, and some do not allow regular diapers or swim pants alone. Bring extra swimsuits for changes, just in case.
- checkEven among year-round indoor pools, the rules differ: Hotel Okura Kobe is for ages 4 and up, and Kobe Portopia Hotel has no children's pool. If you are traveling with a baby, check the age rules first.
- checkHeight and weight limits and extra fees for slides differ by hotel. The slides in the indoor kids' pool at Nesta Resort Kobe require a height of 102 cm or more.
- checkThe summer sun is strong, so a hat and a rash guard help prevent sunburn and also keep kids from getting chilled after they leave the water. Our packing column has tips on choosing swim diapers.
