Umi no Naka Michi is a large park and there are a lot of grassy fields to have a picnic, run around, play sports, or wander around in. I chose to wander.
I loved it because it was so open and big that there was a lot of wandering for me to do. Mommy and Daddy liked it because they could keep an eye on me without having to chase after and tail me. They were impressed and worried about how bold and brave I was all on my own.
