If the last time you’ve visited the Universal Studios Japan in Osaka was on 2014 or even way before, you might want to revisit soon. Their fairly newly opened division of The Wizarding World of Harry Potter is just breathtaking. My family and I had a blast going on the rides and buying every cute food we see. I’m quite a sucker for cute stuff. 😛
Park Hours are sometimes inconsistent. You can check the schedules through here.
The ticket to buy is the Studio Pass. There is such a thing as Express Pass. They have different kinds. There is one that let’s you ride the 7 rides that are in-demand or have the longest line. You can check out more details of this pass by clicking on this link. You would still need to buy the Studio Pass on top of the Express Pass. However, I’d advise against it. Not only because you’d be spending more money but you don’t need the Express Pass to be able to ride these rides. You just need to plan ahead where you need to get your Fast Passes and where you’d be willing to wait in line.
