I'm considering going to Tokyo with my toddler in November, and had a few questions after reading through the traveling with children discussions in this folder. My partner is visiting Meiji University for a week or so (Ikuta campus), and we're thinking of tagging along.

Our son's a pretty good traveler and we're experienced dealing with his jetlag, but the Japanese environment is, well, understandably foreign to me. I'm wondering what the public infrastructure is like for spending the day out and about with a not-quite-potty-trained boy. Are public restrooms plentiful as in the U.S. or harder to find? What sort of facilities can one expect for changing clothes/diapers/washing hands?

Are there public parks or playgrounds for a toddler to climb around and get some exercise? Or would those be a rarity?

Are there different expectations about how children behaving in public (noise levels, eating customs, etc.) that would be good to be more sensitive of?

I'm perhaps optimistically not worried about food or getting around. He's an omnivorous eater and we've been navigating non-stroller-accessible Old Europe for a couple of years now so I'm undaunted by such challenges. But I honestly don't know all that I don't know, so if others have tips for making the day to day travel easier, I'd appreciate it.
