If the younger members of the family are getting fidgety, make tracks to Hakone Toy Museum. With lots of hands-on exhibits and displays, this attraction makes learning exciting.
You'll be spoiled for sightseeing choice when visiting Yumoto. Hakone Toy Museum is an ideal place to begin here, but there are loads of other worthwhile places to consider. Lake Ashi, Hakone Kowakien Yunessun, and Hakone Shrine are close to the interactive exhibit for kids and will round out your day nicely.
