Why children love it: A swimsuit-on onsen water park with themed baths (coffee, wine, green tea, sake), outdoor pools, water slides and a jungle-gym splash area for little ones, so the whole family bathes together.
Honest drawbacks: The swimsuit zone and traditional onsen are priced separately and it gets crowded and pricey; bring or hire swimwear for the water-park areas.
