Santa Claus

Guess what?!
You'll never believe what happened!!
When I was coming to the classroom yesterday morning, I saw Santa Claus!! I am serious!!! This is not a joke!! I swear to God it's true!! He was standing on a bridge on Yostubashi Street, just over Tosabori River. He was an old guy, with a big white bread, and white hair, and he was wearing baggy red pants, or overalls (I couldn't tell which...) and a green long-sleeved shirt with some decorations on it. And he was holding a camera and taking a photo of a boat in the river. Why he was taking a photo of a boat?
Who is he?
Why is he wearing a Santa Claus suit and look exactly like Santa?
What was he doing on Yotsubashi Street in the morning?
Was he really Santa?

I have many questions, but I do not know the answer to any of them.
It is a complete mystery!!!

Anyway, my friends are coming to Japan in a few weeks, and they are going to be in Tokyo. But only for 2 days. Please answer the question below if you want.
"What would you suggest doing on a 48-hour stopover in Tokyo?"
