The new stadium has many things to offer. It has a hotel, sauna, onsen (= Japanese style spa), etc.
This is about the hotel (you can enjoy watching the game from your room of the hotel)

Don't get me wrong, I don't hate baseball and baseball is still very popular here and many are obsessed with baseball. Baseball is a big culture here in Japan, so visiting a baseball stadium to see a baseball game will be a fun experience for people from abroad too. However, I want to see Japan...
I have a very mixed feeling on WBC. Baseball is quite popular here in Japan, and it's good that sports can entertain people here. However, baseball is an enemy seen from football fans like me. I mean, Japan is traditionally "baseball country", and most kids used to choose baseball, not football...
