Hi Mako-san, as Randy has corrected already I will just add some notes for clarity.

Favorite Muppet

The Elmo of Sesame Street has been my favorite since I was a little girl.
He is very cute.

He is at the Universal Studios Japan in Osaka.
He is a very popular there.
We must stand to take a photo with him.

must = we have no choice
can = we have a choice to do it or not

I live in the southern region of Kyushu in Japan.
It takes 2.5 hours by Shinkansen. Is a bit far.

"It is a bit far" is really too short for a complete sentence,
instead, join it to the previous one with a "so, and, but or because".

It takes 2.5 hours by Shinkansen so it is a bit far (for a day trip).

But I'm going to go play there next month.

In English, play is more usually used for children or organised games.
Ex. I can play igo. The children are outside playing. I am going to play basketball.

Adults are more likely to describe their activities as :
business or pleasure (pleasure may also be replaced with recreation).

Ex.
Person 1: I am going to Otemachi next week.
Person 2: Really, business or pleasure ?
Person 1: Business, I will be so busy I wont have time to see anything!
