Kamogawa Sea World

Animal shows, feeding and huge open fields make this one of the better full day escapes when kids need countryside.

A Ferris wheel, swan boats, grass sledding, a children's zoo and nine holes of putting golf.

Four aquariums, including one in the open sea where you can catch a fish and eat it and a lagoon for touching sea creatures, next to a park of rides.

Hotel with a rooftop pool for swimming and a separate shallow pool just for toddlers.

A 112-meter Ferris wheel with a clock face and see-through gondolas, and a Kids Carnival zone of small rides, in a park that's free to walk into.

Design your own cup and pick its soup and toppings, make Chicken Ramen by hand, and climb through a giant play factory as if you were a noodle.
