What kind of place is [Tokyo Dome City]? baseball Ground?

Tokyo Dome, home of the Yomiuri Giants in Bunkyo Ward, Tokyo
I've been walking around the area for nothing.
It seems that you can play all day long from the ballpark, amusement park, shopping to the off-track betting hall.

とても怖かったので、大絶叫でした…………。
