Favorite thing: There were a lot of kids in the vicinity of Odawara castle, and there's no secret of why. There's a small zoo, free to all, and a small amusement park.
I didn't take a look at the amusement park at all, but here's an elephant for you.
Kid friendly place indeed.
Views from the top of the castle
Favorite thing: Odawara is on the coast, sandwiched between two peninsulas, meaning some good views from the top of the castle.
