Fizzy the fun element is what I'm missing, I think. I mean, it's Japan, home of kawaii- but it's absent and everything seems a bit serious.
Can't even say it's the heat - they've had Olympics in hot countries before, with mascots.
I've just read that apparently, the mascots are robots- and they were meant to be the face of the games- but the public don't like them much.
I remember the 2012 mascots were a bit
at first, but everyone soon embraced them. We've got 2 somewhere (I think one of them met the dog when he was puppy, though).
