On Wednesday, March 4 (the day after the Osaka Aquarium and Osaka Castle), we went to the Kids Plaza Osaka. This is basically an indoor park/playground/play area for kids. There is one area that’s a miniature town where kids can go “shopping” and pretend to be postal workers and actually deliver mail. In the very center of this two-story indoor park is a tower that the kids can climb into. There’s also a slide, a science section, a musical section where you can play drums and even a little room where you can dress in traditional Japanese clothing.
